+=head1 SYNOPSIS
+
+B<dh> I<sequence> [B<--with> I<addon>[B<,>I<addon> ...]] [B<--list>] [S<I<debhelper options>>]
+
+=head1 DESCRIPTION
+
+B<dh> runs a sequence of debhelper commands. The supported I<sequence>s
+correspond to the targets of a F<debian/rules> file: B<build-arch>,
+B<build-indep>, B<build>, B<clean>, B<install-indep>, B<install-arch>,
+B<install>, B<binary-arch>, B<binary-indep>, and B<binary>.
+
+=head1 OVERRIDE AND HOOK TARGETS
+
+A F<debian/rules> file using B<dh> can override the command that is run
+at any step in a sequence, by defining an override target. It is also
+possible to inject a command before or after any step without affecting
+the step itself.
+
+=head2 Injecting commands before or after a step
+
+I<Note>: This feature requires debhelper 12.8 or later plus the package must
+use compatibility mode 10 or later.
+
+To inject commands before I<dh_command>, add a target named
+B<execute_before_>I<dh_command> to the rules files. Similarly, if you
+want to inject commands after I<dh_command>, add the target
+B<execute_after_>I<dh_command>. Both targets can be used for the same
+I<dh_command> and also even if the command is overridden (as described in
+L</Overriding a command> below).
+
+When these targets are defined, B<dh> will call the targets respectively
+before or after it would invoke I<dh_command> (or its override target).
+
+=head2 Overriding a command
+
+To override I<dh_command>, add a target named B<override_>I<dh_command> to
+the rules file. When it would normally run I<dh_command>, B<dh> will
+instead call that target. The override target can then run the command with
+additional options, or run entirely different commands instead. See
+examples below.
+
+=head2 Architecture dependent/independent override and hook targets
+
+The override and hook targets can also be defined to run only
+when building architecture dependent or architecture independent
+packages. Use targets with names like B<override_>I<dh_command>B<-arch>
+and B<execute_after_>I<dh_command>B<-indep>.
+
+This feature is available since debhelper 8.9.7 (for override targets)
+and 12.8 (for hook targets).
+
+=head2 Completely empty targets
+
+As a special optimization, B<dh> will skip a target if it is
+completely empty and does not depend on any other target. This is
+mostly useful for override targets, where the command will simply be
+skipped without the overhead of invoking a dummy target.
+
+Note that the target has to be completely empty for this to work:
+
+ # Skip dh_bar - the good and optimized way
+ # Some rationale for skipping dh_bar goes here
+ override_dh_bar:
+
+
+ # Skip dh_foo - the slow way
+ override_dh_foo:
+ # Some rationale for skipping dh_foo goes here
+ # (these comments causes a dummy target to be run)
+
+=head2 Verifying targets are picked up by dh
+
+As of debhelper 13.10, you can use L<dh_assistant(1)> to see which override
+and hook targets will be seen by B<dh>. Here is an example run of L<dh_assistant(1)>
+along with its output:
+
+ $ dh_assistant detect-hook-targets
+ {
+ "commands-not-in-path": [
+ "dh_foo"
+ ],
+ "hook-targets": [
+ {
+ "command": "dh_strip_nondeterminism",
+ "is-empty": true,
+ "package-section-param": null,
+ "target-name": "override_dh_strip_nondeterminism"
+ },
+ {
+ "command": "dh_foo",
+ "is-empty": false,
+ "package-section-param": "-a",
+ "target-name": "override_dh_foo-arch"
+ }
+ ]
+ }
+
+The B<commands-not-in-path> is useful for spotting mistakes in the hook target
+names. A non-empty value implies one of more hook targets are related to a command
+that is either not installed or no command with that name exists at all. It is
+generally worth double checking these.
+
+Additionally, the B<is-empty> attribute for each hook target can be used for seeing
+whether a hook target triggers the L</Completely empty targets> optimization.
+
+If you are interested in the other attributes, please read the L<dh_assistant(1)>
+for the details.
+
+=head3 Verifying targets are picked up by dh (when debhelper is older than 13.10)
+
+
+
+On older versions of debhelper, you have to use B<dh> with B<--no-act>.
+You can use the following command as an example:
+
+ $ dh binary --no-act | grep dh_install | head -n5
+ dh_installdirs
+ dh_install
+ debian/rules execute_after_dh_install
+ dh_installdocs
+ dh_installchangelogs
+
+The B<debian/rules execute_after_dh_install> in the output, which signals
+that B<dh> registered a B<execute_after_dh_install> target and would
+run it directly after L<dh_install(1)>.
+
+Note that L</Completely empty targets> will be omitted in the listing above.
+This makes it a bit harder to spot as you are looking for the omission of
+a command name. But otherwise, the principle remains the same.
+
+=head2 Caveats with hook targets and makefile conditionals
+
+If you choose to wrap a hook target in makefile conditionals, please
+be aware that B<dh> computes all the hook targets a head of time and
+caches the result for that run. Furthermore, the conditionals will be
+invoked again when B<dh> calls the hook target later and will assume
+the answer did not change.
+
+The parsing and caching I<often> happens before B<dh> knows whether it
+will build arch:any (-a) or/and arch:all (-i) packages, which can
+produce confusing results - especially when L<dh_listpackages(1)> is
+part of the conditional.
+
+Most of the problems can be avoided by making the hook target
+unconditional and then have the "body" be partially or completely
+conditional. As an example:
+
+ # SIMPLE: It is well-defined what happens. The hook target
+ # is always considered. The "maybe run this" bit is
+ # conditional but dh_foo is definitely skipped.
+ #
+ # Note: The conditional is evaluated "twice" where its
+ # influences what happens. Once when dh check which hook
+ # targets exist and once when the override_dh_foo hook target
+ # is run. If *either* times return false, "maybe run this"
+ # is skipped.
+ override_dh_foo:
+ ifneq (...)
+ maybe run this
+ endif
+
+ # SIMPLE: This is also well-defined. The hook target is always
+ # run and dh_bar is skipped. The "maybe run this" bit is
+ # conditional as one might expect.
+ #
+ # Note: The conditional is still evaluated multiple times (in
+ # different process each time). However, only the evaluation
+ # that happens when the hook target is run influences what
+ # happens.
+ override_dh_bar:
+ : # Dummy command to force the target to always be run
+ ifneq (...)
+ maybe run this
+ endif
+
+
+ # COMPLICATED: This case can be non-trivial and have sharp edges.
+ # Use at your own peril if dh_listpackages in the conditional.
+ #
+ # Here, either dh_baz is run normally OR "maybe run this" is run
+ # instead.
+ #
+ # And it gets even more complicated to reason about if dh needs to
+ # recurse into debian/rules because you have an "explicit"
+ # standard target (e.g. a "build-arch:" target separate from "%:").
+ ifneq (...)
+ override_dh_baz:
+ maybe run this
+ endif
+
+These recipes are also relevant for conditional dependency targets,
+which are often seen in a variant of the following example:
+
+ COND_TASKS =
+ ifneq (...)
+ COND_TASKS += maybe-run-this
+ endif
+ ...
+
+ maybe-run-this:
+ ...
+
+ # SIMPLE: It is well-defined what happens. Either the
+ # $(COND_TASKS) are skipped or run.
+ #
+ # Note: The conditional is evaluated "twice" where its
+ # influences what happens. Once when dh check which hook
+ # targets exist and once when the override_dh_foo hook target
+ # is run. If *either* times return false, $(COND_TASKS)
+ # is skipped.
+ override_dh_foo: $(COND_TASKS)
+
+
+ # SIMPLE: This is also well-defined. The hook target is always
+ # run and dh_bar is skipped. The $(COND_TASKS) bit is
+ # conditional as one might expect.
+ #
+ # Note: The conditional is still evaluated multiple times (in
+ # different process each time). However, only the evaluation
+ # that happens when the hook target is run influences what
+ # happens.
+ override_dh_bar: $(COND_TASKS)
+ : # Dummy command to force the target to always be run
+
+ # COMPLICATED: This case can be non-trivial and have sharp edges.
+ # Use at your own peril if dh_listpackages in the conditional.
+ #
+ ifneq (...)
+ override_dh_baz: $(COND_TASKS)
+ endif
+
+
+When in doubt, pick the relevant B<SIMPLE> case in the examples above
+that match your need.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--with> I<addon>[B<,>I<addon> ...]
+
+Add the debhelper commands specified by the given addon to appropriate places
+in the sequence of commands that is run. This option can be repeated more
+than once, or multiple addons can be listed, separated by commas.
+This is used when there is a third-party package that provides
+debhelper commands. See the F<PROGRAMMING> file for documentation about
+the sequence addon interface.
+
+A B<Build-Depends> relation on the package B<dh-sequence->I<addon>
+implies a B<--with> I<addon>. This avoids the need for an explicit
+B<--with> in F<debian/rules> that only duplicates what is already
+declared via the build dependencies in F<debian/control>. The
+relation can (since 12.5) be made optional via e.g.
+build-profiles. This enables you to easily disable an addon that
+is only useful with certain profiles (e.g. to facilitate
+bootstrapping).
+
+Since debhelper 12.5, addons can also be activated in B<indep>-only
+mode (via B<Build-Depends-Indep>) or B<arch>-only mode (via
+B<Build-Depends-Arch>). Such addons are only active in the particular
+sequence (e.g. B<binary-indep>) which simplifies dependency
+management for cross-builds.
+
+Please note that addons activated via B<Build-Depends-Indep> or
+B<Build-Depends-Arch> are subject to additional limitations to
+ensure the result is deterministic even when the addon is
+unavailable (e.g. during clean). This implies that some addons
+are incompatible with these restrictions and can only be used via
+B<Build-Depends> (or manually via F<debian/rules>). Currently,
+such addons can only add commands to sequences.
+
+=item B<--without> I<addon>
+
+The inverse of B<--with>, disables using the given addon. This option
+can be repeated more than once, or multiple addons to disable can be
+listed, separated by commas.
+
+=item B<--list>, B<-l>
+
+List all available addons.
+
+When called only with this option, B<dh> can be called from any
+directory (i.e. it does not need access to files from a source
+package).
+
+=item B<--no-act>
+
+Prints commands that would run for a given sequence, but does not run them.
+
+Note that dh normally skips running commands that it knows will do nothing.
+With --no-act, the full list of commands in a sequence is printed.
+
+=back
+
+Other options passed to B<dh> are passed on to each command it runs. This
+can be used to set an option like B<-v> or B<-X> or B<-N>, as well as for more
+specialised options.
+
+=head1 EXAMPLES
+
+To see what commands are included in a sequence, without actually doing
+anything:
+
+ dh binary-arch --no-act
+
+This is a very simple rules file, for packages where the default sequences of
+commands work with no additional options.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+Often you'll want to pass an option to a specific debhelper command. The
+easy way to do with is by adding an override target for that command.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+ override_dh_strip:
+ dh_strip -Xfoo
+
+ override_dh_auto_configure:
+ dh_auto_configure -- --with-foo --disable-bar
+
+Sometimes the automated L<dh_auto_configure(1)> and L<dh_auto_build(1)>
+can't guess what to do for a strange package. Here's how to avoid running
+either and instead run your own commands.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+ override_dh_auto_configure:
+ ./mondoconfig
+
+ override_dh_auto_build:
+ make universe-explode-in-delight
+
+Another common case is wanting to do something manually before or
+after a particular debhelper command is run.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+ # Example assumes debhelper/12.8 and compat 10+
+ execute_after_dh_fixperms:
+ chmod 4755 debian/foo/usr/bin/foo
+
+If you are on an older debhelper or compatibility level, the above
+example would have to be written as.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+ # Older debhelper versions or using compat 9 or lower.
+ override_dh_fixperms:
+ dh_fixperms
+ chmod 4755 debian/foo/usr/bin/foo
+
+Python tools are not run by dh by default, due to the continual change
+in that area. Here is how to use B<dh_python2>.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --with python2
+
+Here is how to force use of Perl's B<Module::Build> build system,
+which can be necessary if debhelper wrongly detects that the package
+uses MakeMaker.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --buildsystem=perl_build
+
+Here is an example of overriding where the B<dh_auto_>I<*> commands find
+the package's source, for a package where the source is located in a
+subdirectory.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --sourcedirectory=src
+
+And here is an example of how to tell the B<dh_auto_>I<*> commands to build
+in a subdirectory, which will be removed on B<clean>.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --builddirectory=build
+
+If your package can be built in parallel, please either use compat 10 or
+pass B<--parallel> to dh. Then B<dpkg-buildpackage -j> will work.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --parallel
+
+If your package cannot be built reliably while using multiple threads,
+please pass B<--no-parallel> to dh (or the relevant B<dh_auto_>I<*>
+command):
+
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --no-parallel
+
+Here is a way to prevent B<dh> from running several commands that you don't
+want it to run, by defining empty override targets for each command.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+ # Commands not to run:
+ override_dh_auto_test override_dh_compress override_dh_fixperms:
+
+A long build process for a separate documentation package can
+be separated out using architecture independent overrides.
+These will be skipped when running build-arch and binary-arch sequences.
+
+ #!/usr/bin/make -f
+ %:
+ dh $@
+
+ override_dh_auto_build-indep:
+ $(MAKE) -C docs
+
+ # No tests needed for docs
+ override_dh_auto_test-indep:
+
+ override_dh_auto_install-indep:
+ $(MAKE) -C docs install
+
+Adding to the example above, suppose you need to chmod a file, but only
+when building the architecture dependent package, as it's not present
+when building only documentation.
+
+ # Example assumes debhelper/12.8 and compat 10+
+ execute_after_dh_fixperms-arch:
+ chmod 4755 debian/foo/usr/bin/foo
+
+=head1 DEBHELPER PROVIDED DH ADDONS
+
+The primary purpose of B<dh> addons is to provide easy integration with
+third-party provided features for debhelper. However, debhelper itself
+also provide a few sequences that can be useful in some cases. These
+are documented in this list:
+
+=over 4
+
+=item build-stamp
+
+A special addon for controlling whether B<dh> (in compat 10 or later)
+will create stamp files to tell whether the build target has been run
+successfully. See L</INTERNALS> for more details.
+
+This addon is active by default but can disabled by using
+B<dh $@ --without build-stamp>
+
+=item dwz (obsolete)
+
+Adds L<dh_dwz(1)> to the sequence in compat level 11 or below. Obsolete
+in compat 12 or later.
+
+=item elf-tools
+
+This addon adds tools related to ELF files to the sequence such as
+L<dh_strip(1)> and L<dh_shlibdeps(1)>
+
+This addon is I<conditionally> active by default for architecture
+specific packages - that is, it is skipped for arch:all packages.
+In the special case where you need these tools to work on arch:all
+packages, you can use B<--with elf-tools> to activate it
+unconditionally.
+
+=item installinitramfs (obsolete)
+
+Adds L<dh_installinitramfs(1)> to the sequence in compat level 11 or below.
+Obsolete in compat 12 or later.
+
+=item root-sequence (internal)
+
+This is reserved for internal usage.
+
+=item single-binary
+
+A special-purpose addon that makes debhelper run in "single binary" mode.
+
+When active, it will pass B<< --destdir=debian/I<package>/ >> to
+L<dh_auto_install(1)>. This makes every file "installed" by the upstream
+build system part of the (only) binary package by default without having
+to use other helpers such as L<dh_install(1)>.
+
+The addon will refuse to activate when the source package lists 2 or more
+binary packages in F<debian/control> as a precaution.
+
+Before compat 15. this behaviour was the default when there was only a single
+binary package listed in F<debian/control>. In compat 15 and later, this
+addon must explicitly be activated for this feature to work.
+
+The rationale for requiring this as an explicit choice is that if it is
+implicit then debhelper will silently change behaviour on adding a new
+binary package. This has caused many RC bugs when maintainers renamed
+a binary and added transitional packages with the intention of supporting
+seamless upgrades. The result would often be two empty binary packages that
+were uploaded to archive with users frustrated as their "upgrade" removed
+their programs.
+
+=item systemd (obsolete)
+
+Adds L<dh_systemd_enable(1)> and L<dh_systemd_start(1)> to the sequence in
+compat level 10 or below. Obsolete in compat 11 or later.
+
+=back
+
+=head1 INTERNALS
+
+If you're curious about B<dh>'s internals, here's how it works under the hood.
+
+In compat 10 (or later), B<dh> creates a stamp file
+F<debian/debhelper-build-stamp> after the build step(s) are complete
+to avoid re-running them. It is possible to avoid the stamp file by
+passing B<--without=build-stamp> to B<dh>. This makes "no clean"
+builds behave more like what some people expect at the expense of
+possibly running the build and test twice (the second time as root or
+under L<fakeroot(1)>).
+
+Inside an override target, B<dh_*> commands will create a log file
+F<debian/package.debhelper.log> to keep track of which packages the
+command(s) have been run for. These log files are then removed once
+the override target is complete.
+
+In compat 9 or earlier, each debhelper command will record
+when it's successfully run in F<debian/package.debhelper.log>. (Which
+B<dh_clean> deletes.) So B<dh> can tell which commands have already
+been run, for which packages, and skip running those commands again.
+
+Each time B<dh> is run (in compat 9 or earlier), it examines the log,
+and finds the last logged command that is in the specified
+sequence. It then continues with the next command in the sequence.
+
+A sequence can also run dependent targets in debian/rules. For
+example, the "binary" sequence runs the "install" target.
+
+B<dh> uses the B<DH_INTERNAL_OPTIONS> environment variable to pass information
+through to debhelper commands that are run inside override targets. The
+contents (and indeed, existence) of this environment variable, as the name
+might suggest, is subject to change at any time.
+
+Commands in the B<build-indep>, B<install-indep> and B<binary-indep>
+sequences are passed the B<-i> option to ensure they only work on
+architecture independent packages, and commands in the B<build-arch>,
+B<install-arch> and B<binary-arch> sequences are passed the B<-a>
+option to ensure they only work on architecture dependent packages.

+
+=head1 SYNOPSIS
+
+B<dh_assistant> B<I<command>> [S<I<additional options>>]
+
+=head1 DESCRIPTION
+
+B<dh_assistant> is a debhelper program that provides introspection into the
+debhelper stack to assist third-party tools (e.g. linters) or third-party
+debhelper implementations not using the debhelper script API (e.g., because
+they are not written in Perl).
+
+=head1 COMMANDS
+
+The B<dh_assistant> supports the following commands:
+
+=head2 active-compat-level (JSON)
+
+B<Synopsis>: B<dh_assistant> B<active-compat-level>
+
+Outputs information about which compat level the package is using.
+
+For packages without valid debhelper compatibility information (whether missing, ambiguous,
+not supported or simply invalid), this command operates on a "best effort" basis and may abort
+when error instead of providing data.
+
+The returned JSON dictionary contains the following key-value pairs:
+
+=over 4
+
+=item active-compat-level
+
+The compat level that debhelper will be using. This is the same as B<DH_COMPAT> when present
+or else B<declared-compat-level>. This can be B<null> when no compat level can be detected.
+
+=item declared-compat-level
+
+The compat level that the package declared as its default compat level. This can be B<null>
+if the package does not declare any compat level at all.
+
+=item declared-compat-level-source
+
+Defines how the compat level was declared. This is null (for the same reason as
+B<declared-compat-level>) or one of:
+
+=over 4
+
+=item debian/compat
+
+The compatibility level was declared in the first line F<debian/compat> file.
+
+=item Build-Depends: debhelper-compat (= <C>)
+
+The compatibility was declared in the F<debian/control> via a build dependency on the
+B<< debhelper-compat (= <C>) >> package in the B<Build-Depends> field. In the output,
+the B<C> is replaced by the actual compatibility level. A full example value would be:
+
+ Build-Depends: debhelper-compat (= 13)
+
+=back
+
+=back
+
+=head2 supported-compat-levels (JSON, CRFA)
+
+B<Synopsis>: B<dh_assistant> B<supported-compat-levels>
+
+Outputs information about which compat levels, this build of debhelper knows
+about.
+
+This command accepts no options or arguments.
+
+=head2 which-build-system (JSON)
+
+B<Synopsis>: B<dh_assistant> B<which-build-system> [S<I<build step>>] [S<I<build system options>>]
+
+Output information about which build system would be used for a particular build step. The build step
+must be one of B<configure>, B<build>, B<test>, B<install> or B<clean> and must be the first argument
+after B<which-build-system> when provided. If omitted, it defaults to B<configure> as it is the
+most reliable step to use auto-detection on in a clean source directory. Note that build steps do not
+always agree when using auto-detection - particularly if the B<configure> step has not been run.
+
+Additionally, the B<clean> step can also provide "surprising" results for builds that rely on
+a separate build directory. In such cases, debhelper will return the first build system that
+uses a separate build directory rather than the one build system that B<configure> would detect.
+This is generally a cosmetic issue as both build systems are all basically a glorified
+B<rm -fr builddir> and more precise detection is functionally irrelevant as far as debhelper is
+concerned.
+
+The option accepts all debhelper build system arguments - i.e., options you can pass to all of
+the B<dh_auto_*> commands plus (for the B<install> step) the B<--destdir> option. These options
+affect the output and auto-detection in various ways. Passing B<-S> or B<--buildsystem>
+overrides the auto-detection (as it does for B<dh_auto_*>) but it still provides introspection
+into the chosen build system.
+
+Things that are useful to know about the output:
+
+=over 4
+
+=item *
+
+The key B<build-system> is the build system that would be used by debhelper for the given
+step (with the given options, debhelper compat level, environment variables and the given
+working directory). When B<-S> and B<--buildsystem> are omitted, this is the result of
+debhelper's auto-detection logic.
+
+The value is valid as a parameter for the B<--buildsystem> option.
+
+The special value B<none> is used to denote that no build system would be used. This value
+is not present in B<--list> parameter for the B<dh_auto_*> commands, but since debhelper/12.9
+the value is accepted for the B<--buildsystem> option.
+
+Note that auto-detection is subject to limitations in regards to third-party build systems.
+While debhelper I<does> support auto-detecting some third-party build systems, they must be
+installed for the detection to work. If they are not installed, the detection logic silently
+skips that build system (often resulting in B<build-system> being B<none> in the output).
+
+=item *
+
+The B<build-directory> and B<buildpath> values serve different but related purposes. The
+B<build-directory> generally mirrors the B<--builddirectory> option where as B<buildpath>
+is the output directory that debhelper will use. Therefore the former will often be null
+when B<--builddirectory> has not been passed while the latter will generally not be null
+(except when B<build-system> is B<none>).
+
+=item *
+
+The B<dest-directory> (B<--destdir>) is undefined for all build steps except the B<install> build
+step (will be output as null or absent). For the same reason, B<--destdir> should only be
+passed for B<install> build step.
+
+Note that if not specified, this value is currently null by default.
+
+=item *
+
+The B<parallel> value is subject to B<DEB_BUILD_OPTIONS>. Notably, if that does not include
+the B<parallel> keyword, then B<parallel> field in the output will always be 1.
+
+=item *
+
+Most fields in the output I<can> be null. Particular if there is no build system is detected
+(or when B<--buildsystem=none>). Additionally, many of the fields can be null even if there
+is a build system if the build system does not use/set/define that variable.
+
+=back
+
+=head2 detect-hook-targets (JSON)
+
+B<Synopsis>: B<dh_assistant> B<detect-hook-targets>
+
+Detects possible override targets and hook targets that L<dh(1)> might use (provided that the
+relevant command is in the sequence).
+
+The detection is based on scanning the rules file for any target that I<might look> like a hook
+target and can therefore list targets that are in fact not hook targets (or are but will never
+be triggered for other reasons).
+
+The detection uses a similar logic for scanning the rules file and is therefore subject to
+makefile conditionals (i.e., the truth value of makefile conditionals can change whether a hook
+target is visible in the output of this command). In theory, you would have to setup up the
+environment to look like it would during a build for getting the most accurate output. Though,
+a lot of packages will not have conditional hook targets, so the "out of the box" behaviour
+will work well in most cases.
+
+The output looks something like this:
+
+ {
+ "commands-not-in-path": [
+ "dh_foo"
+ ],
+ "hook-targets": [
+ {
+ "command": "dh_strip_nondeterminism",
+ "is-empty": true,
+ "package-section-param": null,
+ "target-name": "override_dh_strip_nondeterminism"
+ },
+ {
+ "command": "dh_foo",
+ "is-empty": false,
+ "package-section-param": "-a",
+ "target-name": "override_dh_foo-arch"
+ }
+ ]
+ }
+
+In more details:
+
+=over 4
+
+=item commands-not-in-path
+
+This attribute lists all the commands related to hook targets, which B<dh_assistant> could B<not>
+find in PATH. These are usually caused by either the command not being installed on the system
+where B<dh_assistant> is run or by the command not existing at all.
+
+If you are using this command to verify an hook target is present, please double check that the
+command is spelled correctly.
+
+=item hook-targets
+
+List over hook targets found along with additional information about them.
+
+=over 4
+
+=item command
+
+Attribute that lists which command this hook target is related too.
+
+=item target-name
+
+The actual target name detected in the F<debian/rules> file.
+
+=item is-empty
+
+A boolean that determines whether L<dh(1)> will optimize the hook out at runtime (see "Completely empty targets" in
+L<dh(1)>). Note that empty override targets will still cause L<dh(1)> to skip the original command.
+
+=item package-section-param
+
+This attribute defines what package selection parameter should be passed to B<dh_*> commands used
+in the hook target. It can either be B<-a>, B<-i> or (if no parameter should be used) C<null>.
+
+=back
+
+=back
+
+This command accepts no options or arguments.
+
+=head2 log-installed-files
+
+B<Synopsis>: B<dh_assistant> B<< -pI<pkg> >> I<[--on-behalf-of-cmd=dh_foo]> B<path ...>
+
+Mark one or more paths as installed for a given package. This is useful for telling L<dh_missing(1)> that the
+paths have been installed manually.
+
+The B<--on-behalf-of-cmd> option can be used by third-party tools to have B<dh_assistant> list them as the
+installer of the provided paths. The convention is to use the basename of the tool itself as its name
+(e.g. B<dh_install>).
+
+Please keep in mind that:
+
+=over 4
+
+=item *
+
+B<No> glob or substitution expansion is done by B<dh_assistant> on the provided paths. If you want to use globs,
+have the shell perform the expansion first.
+
+=item *
+
+Paths must be given as relative to the source root directory (e.g., F<debian/tmp/...>)
+
+=item *
+
+You I<can> provide a directory. If you do, the directory and anything recursively below it will be considered
+as installed. Note that it is fine to provide the directory even if paths inside of it has been excluded as long
+as the directory is fully "covered".
+
+=item *
+
+Do not worry about providing the same filename twice in different invocations to B<dh_assistant> due to B<-arch> /
+B<-indep> overrides. While it will be recorded multiple internally, L<dh_missing(1)> will deduplicate when it
+parses the records.
+
+=back
+
+Note this command only I<marks> paths as installed. It does not actually install them - the caller should ensure
+that the paths are in fact handled (or installed).
+
+=head1 COMMAND TAGS
+
+Most commands have one or more of the following "tags" associated with them. Their
+meaning is defined here.
+
+=over 4
+
+=item JSON
+
+The command provides JSON output. See L</JSON OUTPUT> for details.
+
+=item CRFA
+
+I<Mnemonic "Can be Run From Anywhere">
+
+Most commands must be run inside a source package root directory (a directory
+containing F<debian/control>) because debhelper will need the package metadata
+to lookup the information. Any command with this tag are exempt from this
+requirement and is expected to work regardless of where they are run.
+
+=back
+
+=head1 JSON OUTPUT
+
+Most commands uses JSON format as output. Consumers need to be aware that:
+
+=over 4
+
+=item *
+
+Additional keys may be added at any time. For backwards compatibility, the absence
+of a key should in general be interpreted as null unless another default is documented
+or would be "obvious" for that case.
+
+=item *
+
+Many keys can be null/undefined in special cases. As an example, some information may
+be unavailable when this command is run directly from the debhelper source (git repository).
+
+=back
+
+The output will be prettified when stdout is detected as a terminal. If
+you need to pipe the output to a pager/file (etc.) and still want it
+prettified, please use an external JSON formatter. An example of this:
+
+ dh_assistant supported-compat-levels | json_pp | less
+
+=cut
+
+my $JSON_ENCODER = JSON::PP->new->utf8;
+
+# Prettify if we think the user is reading this.

+B<dh_auto_configure> is a debhelper program that tries to automatically

+For example, it looks for and runs a F<./configure> script, F<Makefile.PL>,

+need a configure step; for these B<dh_auto_configure> will exit without
+doing anything.
+
+This is intended to work for about 90% of packages. If it doesn't work,

+
+=head1 DESCRIPTION
+
+B<dh_auto_install> is a debhelper program that tries to automatically install
+built files. It does so by running the appropriate command for the build
+system it detects the package uses. For example, if there's a F<Makefile> and
+it contains a B<install> target, then this is done by running B<make> (or B<MAKE>,
+if the environment variable is set). If there is a F<setup.py> or F<Build.PL>,
+it is used. Note that the Ant build system does not support installation,
+so B<dh_auto_install> will not install files built using Ant.
+
+In compat 15 or later, B<dh_auto_install> will use F<debian/tmp> as the default
+B<--destdir> and should be moved from there to the appropriate package build
+directory using L<dh_install(1)> or similar tools. Though if the B<single-binary>
+addon for L<dh(1)> is activated, then it will pass an explicit
+B<< --destdir=debian/I<package>/ >> to B<dh_auto_install>.
+
+For earlier compat levels then unless B<--destdir> option is
+specified, the files are installed into debian/I<package>/ if there is only one
+binary package. In the multiple binary package case, the files are instead
+installed into F<debian/tmp/>, and should be moved from there to the
+appropriate package build directory using L<dh_install(1)> or similar tools.
+
+B<DESTDIR> is used to tell make where to install the files.
+If the Makefile was generated by MakeMaker from a F<Makefile.PL>, it will
+automatically set B<PREFIX=/usr> too, since such Makefiles need that.
+
+This is intended to work for about 90% of packages. If it doesn't work, or
+tries to use the wrong install target, you're encouraged to skip using
+B<dh_auto_install> at all, and just run make install manually.

+B<dh_clean> [S<I<debhelper options>>] [B<-k>] [B<-d>] [B<-X>I<item>] [S<I<path> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_clean> is a debhelper program that is responsible for cleaning up. It should
+be the last step of the B<clean> target and other debhelper commands generally
+assume that B<dh_clean> will clean up after them.
+
+It removes the package build directories, and removes some other files including
+F<debian/files>, and any detritus left behind by other debhelper commands. It
+also removes common files that should not appear in a Debian diff:
+ #*# *~ DEADJOE *.orig *.rej *.SUMS TAGS .deps/* *.P *-stamp
+
+It does not run "make clean" to clean up after the build process. Use
+L<dh_auto_clean(1)> to do things like that.

+to the new files.
+
+By default, B<dh_compress> compresses files that Debian policy mandates should
+be compressed, namely all files in F<usr/share/info>, F<usr/share/man>,
+files in F<usr/share/doc> that are larger than 4k in size,
+(except the F<copyright> file, F<.html> and other web files, image files, and files
+that appear to be already compressed based on their extensions), and all
+F<changelog> files. Plus PCF fonts underneath F<usr/share/fonts/X11/>

+outputs will be compressed. The shell script will be run from inside the
+package build directory. Note though that using B<-X> is a much better idea in

+B<dh_dwz> [S<I<debhelper options>>] [B<-X>I<item>] [S<B<--> I<params>>]
+
+=head1 DESCRIPTION
+
+B<dh_dwz> is a debhelper program that will optimize the (uncompressed)
+size of the DWARF debug information in ELF binaries. It does so by
+running L<dwz(1)> on all the ELF binaries in the package.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--dwz-multifile>, B<--no-dwz-multifile>
+
+Whether L<dwz(1)> should generate a I<multifile> from the ELF binaries
+in the same package. When enabled, if a package ships at least 2 ELF
+binaries, B<dh_dwz> will instruct L<dwz(1)> to generate a multifile
+for the package.
+
+By default, B<dh_dwz> will attempt to create a multifile but will
+continue without if L<dwz(1)> does not create one (but succeeds anyway).
+This commonly happens when the debug files do not contain debug
+symbols (e.g. a missing -g to the compiler) or when the debug
+symbols are compressed (see Debian bug #931891). If B<--dwz-multifile>
+is passed, then B<dh_dwz> will abort with an error if L<dwz(1)> does
+not create a multifile.
+
+Note this options may not work if a package contains more ELF binaries
+than can fit on a single command line. If this becomes a problem,
+please pass B<--no-dwz-multifile> to work around the issue.
+
+The generated multifile will be compressed with B<objcopy
+--compress-debug-sections>.
+
+Note for B<udeb> packages: B<dh_dwz> will never generate multifiles
+for B<udeb> packages. It will still use B<dwz> to reduce the
+file size of debug files if it finds any.
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename from being
+stripped. You may use this option multiple times to build up a list of
+things to exclude.
+
+=item B<--> I<params>
+
+Pass I<params> to L<dwz(1)> when it processes ELF binaries. This is
+mostly useful for setting memory related parameters (e.g. -l and -L).
+
+=back
+
+=head1 NOTES
+
+If the B<DEB_BUILD_OPTIONS> environment variable contains B<nostrip>,
+nothing will be stripped, in accordance with Debian policy (section
+10.1 "Binaries").
+
+While this tool technically does not remove debug information from
+binaries, it is still skipped when the B<DEB_BUILD_OPTIONS>
+environment variable contains B<nostrip>. This is because B<nostrip>
+is often used to optimize build times (e.g. for "build and
+test"-cycles) rather than optimizing for size.

+
+B<dh_fixperms> [S<I<debhelper options>>] [B<-X>I<item>]
+
+=head1 DESCRIPTION
+
+B<dh_fixperms> is a debhelper program that is responsible for setting the
+permissions of files and directories in package build directories to a
+sane state -- a state that complies with Debian policy.
+
+B<dh_fixperms> makes all files in F<usr/share/doc> in the package
+build directory (excluding files in the F<examples/> directory) be
+mode 644. It also changes the permissions of all man pages to mode
+644. It removes group and other write permission from all files. It
+removes execute permissions from any libraries, headers, Perl modules,
+or desktop files that have it set. It makes all files in the standard
+F<bin> and F<sbin> directories, F<usr/games/> and F<etc/init.d>
+executable (since v4). Finally, it removes the setuid and setgid bits
+from all files in the package.
+
+When the I<Rules-Requires-Root> field has the (effective) value of
+I<binary-targets>, B<dh_fixperms> will also reset the ownership of
+all paths to "root:root".
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-X>I<item>, B<--exclude> I<item>
+
+Exclude files that contain I<item> anywhere in their filename from having
+their permissions changed. You may use this option multiple times to build
+up a list of things to exclude.

+
+B<dh_gencontrol> is a debhelper program that is responsible for generating
+control files, and installing them into the I<DEBIAN> directory with the
+proper permissions.
+
+This program is merely a wrapper around L<dpkg-gencontrol(1)>, which
+calls it once for each package being acted on (plus related dbgsym
+packages), and passes in some additional useful flags.
+
+B<Note> that if you use B<dh_gencontrol>, you must also use
+L<dh_builddeb(1)> to build the packages. Otherwise, your build may
+fail to build as B<dh_gencontrol> (via L<dpkg-gencontrol(1)>) declares
+which packages are built. As debhelper automatically generates dbgsym
+packages, it some times adds additional packages, which will be built
+by L<dh_builddeb(1)>.

+B<dh_install> [B<-X>I<item>] [B<--autodest>] [B<--sourcedir=>I<dir>] [S<I<debhelper options>>] [S<I<file|dir> ... I<destdir>>]
+
+=head1 DESCRIPTION
+
+B<dh_install> is a debhelper program that handles installing files into package
+build directories. There are many B<dh_install>I<*> commands that handle installing
+specific types of files such as documentation, examples, man pages, and so on,
+and they should be used when possible as they often have extra intelligence for
+those particular tasks. B<dh_install>, then, is useful for installing everything
+else, for which no particular intelligence is needed. It is a replacement for
+the old B<dh_movefiles> command.
+
+This program may be used in one of two ways. If you just have a file or two
+that the upstream Makefile does not install for you, you can run B<dh_install>
+on them to move them into place. On the other hand, maybe you have a large
+package that builds multiple binary packages. You can use the upstream
+F<Makefile> to install it all into F<debian/tmp>, and then use B<dh_install> to copy
+directories and files from there into the proper package build directories.
+
+From debhelper compatibility level 7 on, B<dh_install> will fall back to
+looking in F<debian/tmp> for files, if it does not find them in the current
+directory (or wherever you've told it to look using B<--sourcedir>).
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.install
+
+List the files to install into each package and the directory they should be
+installed to. The format is a set of lines, where each line lists a file or
+files to install, and at the end of the line tells the directory it should be
+installed in. The name of the files (or directories) to install should be given
+relative to the current directory, while the installation directory is given
+relative to the package build directory. You may use wildcards in the names of
+the files to install.
+
+Note that if you list exactly one filename or wildcard-pattern on a line by
+itself, with no explicit destination, then B<dh_install>
+will automatically guess the destination to use, the same as if the
+--autodest option were used.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.
+
+=item debian/not-installed
+
+Used with the deprecated B<--list-missing> and B<--fail-missing> options.
+Please refer to L<dh_missing(1)> for the documentation of this file.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--list-missing>
+
+B<Deprecated>: Please use B<dh_missing --list-missing> instead. If you use
+this option, B<dh_install> will call B<dh_missing> with that option after it has
+processed all the files. Please see L<dh_missing(1)> for the documentation of
+this option.
+
+This option is removed in compat 12.
+
+=item B<--fail-missing>
+
+B<Deprecated>: Please use B<dh_missing --fail-missing> instead. If you use
+this option, B<dh_install> will call B<dh_missing> with that option after it has
+processed all the files. Please see L<dh_missing(1)> for the documentation of
+this option.
+
+This option is removed in compat 12.
+
+=item B<--sourcedir=>I<dir>
+
+Look in the specified directory for files to be installed.
+
+Note that this is not the same as the B<--sourcedirectory> option used
+by the B<dh_auto_>I<*> commands. You rarely need to use this option, since
+B<dh_install> automatically looks for files in F<debian/tmp> in debhelper
+compatibility level 7 and above.
+
+=item B<--autodest>
+
+Guess as the destination directory to install things to. If this is
+specified, you should not list destination directories in
+F<debian/package.install> files or on the command line. Instead, B<dh_install>
+will guess as follows:
+
+Strip off F<debian/tmp> (or the sourcedir if one is given) from the front of
+the filename, if it is present, and install into the dirname of the
+filename. So if the filename is F<debian/tmp/usr/bin>, then that directory
+will be copied to F<debian/package/usr/>. If the filename is
+F<debian/tmp/etc/passwd>, it will be copied to F<debian/package/etc/>.
+
+=item I<file|dir> ... I<destdir>
+
+Lists files (or directories) to install and where to install them to.
+The files will be installed into the first package F<dh_install> acts on.

+
+=head1 LIMITATIONS
+
+B<dh_install> cannot rename files or directories, it can only install them
+with the names they already have into wherever you want in the package
+build tree.
+
+However, renaming can be achieved by using B<dh-exec> with compatibility level 9 or
+later. An example debian/I<package>.install file using B<dh-exec>
+could look like:
+
+ #!/usr/bin/dh-exec
+ debian/default.conf => /etc/my-package/start.conf
+
+Please remember the following three things:
+
+=over 4
+
+=item * The package must be using compatibility level 9 or later (see L<debhelper(7)>)
+
+=item * The package will need a build-dependency on dh-exec.
+
+=item * The install file must be marked as executable.

+
+Catalogs will be registered in a supercatalog, in
+F</etc/sgml/I<package>.cat>.
+
+This command automatically adds maintainer script snippets for
+registering and unregistering the catalogs and supercatalogs (unless
+B<-n> is used). These snippets are inserted into the maintainer
+scripts and the B<triggers> file by B<dh_installdeb>; see
+L<dh_installdeb(1)> for an explanation of Debhelper maintainer script
+snippets.
+
+A dependency on B<sgml-base> will be added to B<${misc:Depends}>, so be
+sure your package uses that variable in F<debian/control>.

+B<dh_installchangelogs> [S<I<debhelper options>>] [B<-k>] [B<-X>I<item>] [B<--no-trim>] [I<upstream>]
+
+=head1 DESCRIPTION
+
+B<dh_installchangelogs> is a debhelper program that is responsible for
+installing changelogs into package build directories.
+
+An upstream F<changelog> file may be specified as an option. If none
+is specified, B<dh_installchangelogs> may look for files with names
+that seem likely to be changelogs as described in the next paragraphs.
+
+In non-native packages, B<dh_installchangelogs> will first look for
+changelog files installed by the upstream build system into F<<
+usr/share/doc/I<package> >> (of the package build directory) and
+rename the most likely candidate (if any) to F<<
+usr/share/doc/I<package>/changelog >>. Note that
+B<dh_installchangelogs> does I<not> look into any source directory
+(such as F<debian/tmp>). Otherwise, B<dh_installchangelogs> (at
+compatibility level 7 or any later) will look for changelog files in
+the source directory (e.g. the root or the F<docs> subdirectory). It
+will look for F<changelog>, F<changes> and F<history> optionally with
+common extensions (such as F<.txt>, F<.md> and F<.rst>).
+
+If a changelog file is specified and is an F<html> file (determined by file
+extension), it will be installed as F<usr/share/doc/package/changelog.html>
+instead. If the html changelog is converted to plain text, that variant
+can be specified as a second parameter. When no plain text variant is
+specified, a short F<usr/share/doc/package/changelog> is generated,
+pointing readers at the html changelog file.
+
+The B<debchange>-style Debian changelogs are trimmed to include only
+entries more recent than the release date of I<oldstable>.
+No trimming will be performed if the B<--no-trim> option is passed or
+if the B<DEB_BUILD_OPTIONS> environment variable contains B<notrimdch>.

+Use the package specific name if I<package> needs a different
+F<NEWS> or F<changelog> file.

+Keep the original name of the upstream changelog. This will be accomplished

+
+B<dh_installdeb> [S<I<debhelper options>>]
+
+=head1 DESCRIPTION
+
+B<dh_installdeb> is a debhelper program that is responsible for installing
+files into the F<DEBIAN> directories in package build directories with the
+correct permissions.
+
+=head1 FILES
+
+=over 4
+
+=item I<package>.postinst
+
+=item I<package>.preinst
+
+=item I<package>.postrm
+
+=item I<package>.prerm
+
+These maintainer scripts are installed into the F<DEBIAN> directory.
+
+B<dh_installdeb> will perform substitution of known tokens of
+the pattern B<#TOKEN#>. In generally, scripts will want to
+include the B<#DEBHELPER#> to benefit from the shell scripts
+generated by debhelper commands (including those from
+B<dh_installdeb> when it processes I<package>.maintscript files).
+
+The B<#DEBHELPER#> token should be placed on its own line as it is
+often replaced by a multi-line shell script.
+
+=item I<package>.triggers
+
+=item I<package>.shlibs
+
+These control files are installed into the F<DEBIAN> directory.
+
+Note that I<package>.shlibs is only installed in compat level 9 and
+earlier. In compat 10, please use L<dh_makeshlibs(1)>.
+
+=item I<package>.conffiles
+
+This file will be installed into the F<DEBIAN> directory. The
+provided file will be enriched by debhelper to include all the
+B<conffiles> auto-detected by debhelper (the maintainer should
+not list there as debhelper assumes it should handle that part).
+
+This file is primarily useful for using "special" entries such as
+the B<< remove-on-upgrade >> feature from dpkg.
+
+=item I<package>.maintscript
+
+Lines in this file correspond to L<dpkg-maintscript-helper(1)>
+commands and parameters. However, the "maint-script-parameters"
+should I<not> be included as debhelper will add those automatically.
+
+Example:
+
+ # Correct
+ rm_conffile /etc/obsolete.conf 0.2~ foo
+ # INCORRECT
+ rm_conffile /etc/obsolete.conf 0.2~ foo -- "$@"
+
+In compat 10 or later, any shell metacharacters will be escaped, so
+arbitrary shell code cannot be inserted here. For example, a line
+such as C<mv_conffile /etc/oldconffile /etc/newconffile> will insert
+maintainer script snippets into all maintainer scripts sufficient to
+move that conffile.
+
+It was also the intention to escape shell metacharacters in previous
+compat levels. However, it did not work properly and as such it was
+possible to embed arbitrary shell code in earlier compat levels.
+
+The B<dh_installdeb> tool will do some basic validation of some of
+the commands listed in this file to catch common mistakes. The
+validation is enabled as a warning since compat 10 and as a hard
+error in compat 12.
+
+Where possible, B<dh_installdeb> may choose to rewrite some or all
+of the entries into equivalent features supported in dpkg without
+relying on maintainer scripts at its sole discretion (examples
+include rewriting B<rm_conffile> into dpkg's B<remove-on-upgrade>).
+The minimum requirement for activating this feature is that debhelper
+runs in compat 10 or later.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-D>I<TOKEN=VALUE>, B<--define> I<TOKEN=VALUE>
+
+Define tokens to be replaced inside the maintainer scripts when
+it is generated. Please note that the limitations described in
+L</Limitations in token names> also applies to tokens defined
+on the command line. Invalid token names will trigger an error.
+
+In the simple case, this parameter will cause B<< #I<TOKEN># >>
+to be replaced by I<VALUE>. If I<VALUE> starts with a literal
+I<@>-sign, then I<VALUE> is expected to point to a file
+containing the actual value to insert.
+
+An explicit declared token with this parameter will replace built-in
+tokens.
+
+Test examples to aid with the understanding:
+
+ cat >> debian/postinst <<EOF
+ #SIMPLE#
+ #FILEBASED#
+ EOF
+ echo -n "Complex value" > some-file
+ dh_installdeb --define SIMPLE=direct --define FILEBASED=@some-file
+
+In this example, B<#SIMPLE#> will expand to B<direct> and B<#FILEBASED#>
+will expand to B<Complex value>.
+
+It is also possible to set package-specific values for a given
+token. This is useful when B<dh_installdeb> is acting on multiple
+packages that need different values for the same token. This is
+done by prefixing the token name with B<< pkg.I<package-name>. >>.
+
+This can be used as in the following example:
+
+ cat >> debian/foo.postinst <<EOF
+ # Script for #PACKAGE#
+ #TOKEN#
+ EOF
+ cat >> debian/bar.postinst <<EOF
+ # Script for #PACKAGE#
+ #TOKEN#
+ EOF
+ cat >> debian/baz.postinst <<EOF
+ # Script for #PACKAGE#
+ #TOKEN#
+ EOF
+ dh_installdeb -pfoo -pbar -pbaz --define TOKEN=default --define pkg.bar.TOKEN=unique-bar-value \
+ --define pkg.baz.TOKEN=unique-baz-value
+
+In this example, B<#TOKEN#> will expand to B<default> in F<debian/foo.postinst>,
+to B<unique-bar-value> in F<debian/bar.postinst> and to B<unique-baz-value>
+in F<debian/baz.postinst>.
+
+Note that the B<#pkg.*#> tokens will be visible in all scripts acted on. E.g.
+you can refer to B<#pkg.bar.TOKEN#> inside F<debian/foo.postinst> and it will
+be replaced by B<unique-bar-value>.
+
+=back
+
+=head1 SUBSTITUTION IN MAINTAINER SCRIPTS
+
+The B<dh_installdeb> will automatically replace the following tokens
+inside a provided maintainer script (if not replaced via B<-D>/B<--define>):
+
+=over 4
+
+=item #DEBHELPER#
+
+This token is by default replaced with generated shell snippets debhelper
+commands. This includes the snippets generated by
+B<dh_installdeb> from I<package>.maintscript file (if present).
+
+=item #DEB_HOST_I<NAME>#, #DEB_BUILD_I<NAME>#, #DEB_TARGET_I<NAME>#
+
+These tokens are replaced with the respective variable from
+L<dpkg-architecture(1)>. In almost all cases, you will want
+use the B<< #DEB_HOST_I<NAME> >> variant in a script to ensure
+you get the right value when cross-building.
+
+On a best effort, tokens of this pattern that do not match
+a variable in L<dpkg-architecture(1)> will be left as-is.
+
+=item #ENV.I<NAME>#
+
+These tokens of this form will be replaced with value of the
+corresponding environment variable. If the environment
+variable is unset, the token is replaced with the empty
+string.
+
+Note that there are limits on which names can be used (see
+L</Limitations in token names>).
+
+=item #PACKAGE#
+
+This token is by default replaced by the package name, which will contain
+the concrete script.
+
+=back
+
+=head2 Limitations in token names
+
+All tokens intended to be substituted must match the regex: #[A-Za-z0-9_.+]+#
+
+Tokens that do not match that regex will be silently ignored if found in the
+script template. Invalid token names passed to B<-D> or B<--define> will
+cause B<dh_installdeb> to reject the command with an error in most cases.

+=head1 SYNOPSIS
+
+B<dh_installdebconf> [S<I<debhelper options>>] [B<-n>] [S<B<--> I<params>>]
+
+=head1 DESCRIPTION
+
+B<dh_installdebconf> is a debhelper program that is responsible for installing
+files used by debconf into package build directories.
+
+It also automatically generates the F<postrm> commands needed to interface
+with debconf. The commands are added to the maintainer scripts by
+B<dh_installdeb>. See L<dh_installdeb(1)> for an explanation of how that
+works.
+
+Note that if you use debconf, your package probably needs to depend on it
+(it will be added to B<${misc:Depends}> by this program).
+
+Note that for your config script to be called by B<dpkg>, your F<postinst>
+needs to source debconf's confmodule. B<dh_installdebconf> does not
+install this statement into the F<postinst> automatically as it is too
+hard to do it right.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.config
+
+This is the debconf F<config> script, and is installed into the F<DEBIAN>
+directory in the package build directory.
+
+Inside the script, the token B<#DEBHELPER#> is replaced with
+shell script snippets generated by other debhelper commands.
+
+=item debian/I<package>.templates
+
+This is the debconf F<templates> file, and is installed into the F<DEBIAN>
+directory in the package build directory.
+
+=item F<debian/po/>
+
+If this directory is present, this program will automatically use
+L<po2debconf(1)> to generate merged templates
+files that include the translations from there.
+
+For this to work, your package should build-depend on F<po-debconf>.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--no-scripts>
+
+Do not modify F<postrm> script.
+
+=item B<--> I<params>
+
+Pass the params to B<po2debconf>.
+
+=item B<-D>I<TOKEN=VALUE>, B<--define> I<TOKEN=VALUE>
+
+Define tokens to be replaced inside the maintainer scripts when
+it is generated. Please note that the limitations described in
+L</Limitations in token names> also applies to tokens defined
+on the command line. Invalid token names will trigger an error.
+
+In the simple case, this parameter will cause B<< #I<TOKEN># >>
+to be replaced by I<VALUE>. If I<VALUE> starts with a literal
+I<@>-sign, then I<VALUE> is expected to point to a file
+containing the actual value to insert.
+
+An explicit declared token with this parameter will replace built-in
+tokens.
+
+Test examples to aid with the understanding:
+
+ cat >> debian/config <<EOF
+ #SIMPLE#
+ #FILEBASED#
+ EOF
+ echo -n "Complex value" > some-file
+ dh_installdeb --define SIMPLE=direct --define FILEBASED=@some-file
+
+In this example, B<#SIMPLE#> will expand to B<direct> and B<#FILEBASED#>
+will expand to B<Complex value>.
+
+It is also possible to set package-specific values for a given
+token. This is useful when B<dh_installdebconf> is acting on multiple
+packages that need different values for the same token. This is
+done by prefixing the token name with B<< pkg.I<package-name>. >>.
+
+This can be used as in the following example:
+
+ cat >> debian/foo.config <<EOF
+ # Script for #PACKAGE#
+ #TOKEN#
+ EOF
+ cat >> debian/bar.config <<EOF
+ # Script for #PACKAGE#
+ #TOKEN#
+ EOF
+ cat >> debian/baz.config <<EOF
+ # Script for #PACKAGE#
+ #TOKEN#
+ EOF
+ dh_installdebconf -pfoo -pbar -pbaz --define TOKEN=default --define pkg.bar.TOKEN=unique-bar-value \
+ --define pkg.baz.TOKEN=unique-baz-value
+
+In this example, B<#TOKEN#> will expand to B<default> in F<debian/foo.config>,
+to B<unique-bar-value> in F<debian/bar.config> and to B<unique-baz-value>
+in F<debian/baz.config>.
+
+Note that the B<#pkg.*#> tokens will be visible in all scripts acted on. E.g.
+you can refer to B<#pkg.bar.TOKEN#> inside F<debian/foo.config> and it will
+be replaced by B<unique-bar-value>.
+
+=back
+
+=head1 SUBSTITUTION IN MAINTAINER SCRIPTS
+
+The B<dh_installdebconf> will automatically replace the following tokens
+inside a provided maintainer script (if not replaced via B<-D>/B<--define>):
+
+=over 4
+
+=item #DEB_HOST_I<NAME>#, #DEB_BUILD_I<NAME>#, #DEB_TARGET_I<NAME>#
+
+These tokens are replaced with the respective variable from
+L<dpkg-architecture(1)>. In almost all cases, you will want
+use the B<< #DEB_HOST_I<NAME> >> variant in a script to ensure
+you get the right value when cross-building.
+
+On a best effort, tokens of this pattern that do not match
+a variable in L<dpkg-architecture(1)> will be left as-is.
+
+=item #ENV.I<NAME>#
+
+These tokens of this form will be replaced with value of the
+corresponding environment variable. If the environment
+variable is unset, the token is replaced with the empty
+string.
+
+Note that there are limits on which names can be used (see
+L</Limitations in token names>).
+
+=item #PACKAGE#
+
+This token is by default replaced by the package name, which will contain
+the concrete script.
+
+=back
+
+=head2 Limitations in token names
+
+All tokens intended to be substituted must match the regex: #[A-Za-z0-9_.+]+#
+
+Tokens that do not match that regex will be silently ignored if found in the
+script template. Invalid token names passed to B<-D> or B<--define> will
+cause B<dh_installdebconf> to reject the command with an error in most cases.

+
+B<dh_installdocs> is a debhelper program that is responsible for installing
+documentation into F<usr/share/doc/package> in package build directories.
+
+In compat 10 and earlier, L<dh_install(1)> may be a better tool for handling
+the upstream documentation, when upstream's own build system installs all the desired documentation
+correctly. In this case, B<dh_installdocs> is still useful for installing
+packaging related documentation (e.g. the F<debian/copyright> file).
+
+From debhelper compatibility level 11 on, B<dh_install> will fall back to
+looking in F<debian/tmp> for files, if it does not find them in the current
+directory (or wherever you've told it to look using B<--sourcedir>).
+
+In compat 11 and later, B<dh_installdocs> offers many of the features that
+L<dh_install(1)> also has. Furthermore, B<dh_installdocs> also supports
+the B<nodoc> build profile to exclude documentation (regardless of compat
+level).
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.docs
+
+List documentation files to be installed into I<package>.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.
+
+=item F<debian/copyright>
+
+The copyright file is installed into all packages, unless a more
+specific copyright file is available.
+
+=item debian/I<package>.copyright
+
+=item debian/I<package>.README.Debian
+
+=item debian/I<package>.TODO
+
+Each of these files is automatically installed if present for a
+I<package>.
+
+=item F<debian/README.Debian>
+
+=item F<debian/TODO>
+
+These files are installed into the first binary package listed in
+debian/control.
+
+Note that F<README.debian> files are also installed as F<README.Debian>,
+and F<TODO> files will be installed as F<TODO.Debian> in non-native packages.
+
+=item debian/I<package>.doc-base
+
+Installed as doc-base control files. Note that the doc-id will be
+determined from the B<Document:> entry in the doc-base control file in
+question. In the event that multiple doc-base files in a single source
+package share the same doc-id, they will be installed to
+usr/share/doc-base/package instead of usr/share/doc-base/doc-id.
+
+=item debian/I<package>.doc-base.*
+
+If your package needs to register more than one document, you need
+multiple doc-base files, and can name them like this. In the event
+that multiple doc-base files of this style in a single source package
+share the same doc-id, they will be installed to
+usr/share/doc-base/package-* instead of usr/share/doc-base/doc-id.
+
+Please be aware that this deduplication is currently done in memory
+only, so for now it requires B<dh_installdocs> to be called no more
+than once during the package build. Calling B<dh_installdocs
+-p>I<package> in combination with using
+F<debian/>I<package>F<.doc-base.*> files can lead to uninstallable
+packages. See L<https://bugs.debian.org/980903> for details.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-A>, B<--all>
+
+Install all files specified by command line parameters in ALL packages
+acted on.
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename from
+being installed. Note that this includes doc-base files.
+
+=item B<--sourcedir=>I<dir>
+
+Look in the specified directory for files to be installed. This option
+requires compat 11 or later (it is silently ignored in compat 10 or earlier).
+
+Note that this is not the same as the B<--sourcedirectory> option used
+by the B<dh_auto_>I<*> commands. You rarely need to use this option, since
+B<dh_installman> automatically looks for files in F<debian/tmp> in debhelper
+compatibility level 11 and above.
+
+=item B<--doc-main-package=>I<main-package>
+
+Set the main package for a documentation package. This is used to
+install the documentation of the documentation package in F<<
+/usr/share/doc/I<main-package> >> as recommended by the Debian policy
+manual 3.9.7 in §12.3.
+
+In compat 11 (or later), this option is only useful if debhelper's
+auto-detection of the main package is wrong. The option can also be
+used to silence a warning from debhelper when the auto-detection fails
+but the default happens to be correct.
+
+This option cannot be used when B<dh_installdocs> is instructed to act
+on multiple packages. If you need this option, you will generally
+need to combine it with B<-p> to ensure exactly one package is acted
+on.
+
+Please keep in mind that some documentation (the copyright file,
+README.Debian, etc.) will be unaffected by this option.
+
+=item B<--link-doc=>I<package>
+
+Make the documentation directory of all packages acted on be a symlink to
+the documentation directory of I<package>. This has no effect when acting on
+I<package> itself, or if the documentation directory to be created already
+exists when B<dh_installdocs> is run. To comply with policy, I<package> must
+be a binary package that comes from the same source package.
+
+debhelper will try to avoid installing files into linked documentation
+directories that would cause conflicts with the linked package. The B<-A>
+option will have no effect on packages with linked documentation
+directories, and F<copyright>, F<changelog>, F<README.Debian>, and F<TODO> files will
+not be installed.
+
+(An older method to accomplish the same thing, which is still supported,
+is to make the documentation directory of a package be a dangling symlink,
+before calling B<dh_installdocs>.)
+
+Please note that this option only applies to the documentation
+directory for the package itself. When the package ships
+documentation for another package (e.g. see B<--doc-main-package>), it
+will not use a symlink for the documentation of the other package.
+
+
+B<CAVEAT 1>: If a previous version of the package was built without this
+option and is now built with it (or vice-versa), it requires a "dir to
+symlink" (or "symlink to dir") migration. Since debhelper has no
+knowledge of previous versions, you have to enable this migration
+itself.
+
+This can be done by providing a "debian/I<package>.maintscript" file
+and using L<dh_installdeb(1)> to provide the relevant maintainer
+script snippets.
+
+B<CAVEAT 2>: The use of B<--link-doc> should only be done when the
+packages have same "architecture" type. A link from an architecture
+independent package to an architecture dependent package (or vice
+versa) will not work. Since compat 10, debhelper will actively reject
+unsupported combinations.
+
+=item I<file> ...
+
+Install these files as documentation into the first package acted on. (Or
+in all packages if B<-A> is specified).

+
+=head1 NOTES
+
+Note that B<dh_installdocs> will happily copy entire directory hierarchies if
+you ask it to (similar to B<cp -a>). If it is asked to install a
+directory, it will install the complete contents of the directory.

+
+=head1 DESCRIPTION
+
+B<dh_installexamples> is a debhelper program that is responsible for
+installing examples into F<usr/share/doc/package/examples> in package
+build directories.
+
+From debhelper compatibility level 11 on, B<dh_install> will fall back to
+looking in F<debian/tmp> for files, if it does not find them in the current
+directory (or wherever you've told it to look using B<--sourcedir>).
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.examples
+
+Lists example files or directories to be installed.
+
+If upstream provides an F<examples> directory, you will often want to use B<examples/*> rather
+than B<examples> in this file. The latter would create
+F<< /usr/share/doc/I<package>/examples/examples >>, which is rarely what you want.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-A>, B<--all>
+
+Install any files specified by command line parameters in ALL packages
+acted on.
+
+=item B<--sourcedir=>I<dir>
+
+Look in the specified directory for files to be installed. This option
+requires compat 11 or later (it is silently ignored in compat 10 or earlier).
+
+Note that this is not the same as the B<--sourcedirectory> option used
+by the B<dh_auto_>I<*> commands. You rarely need to use this option, since
+B<dh_installexamples> automatically looks for files in F<debian/tmp> in debhelper
+compatibility level 11 and above.
+
+=item B<--doc-main-package=>I<main-package>
+
+Set the main package for a documentation package. This is used to
+install the documentation of the documentation package in F<<
+/usr/share/doc/I<main-package> >> as recommended by the Debian policy
+manual 3.9.7 in §12.3.
+
+In compat 11 (or later), this option is only useful if debhelper's
+auto-detection of the main package is wrong. The option can also be
+used to silence a warning from debhelper when the auto-detection fails
+but the default happens to be correct.
+
+This option cannot be used when B<dh_installexamples> is instructed to act
+on multiple packages. If you need this option, you will generally
+need to combine it with B<-p> to ensure exactly one package is acted
+on.
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename from
+being installed.
+
+=item I<file> ...
+
+Install these files (or directories) as examples into the first package
+acted on. (Or into all packages if B<-A> is specified.)
+
+=back
+
+=head1 NOTES
+
+Note that B<dh_installexamples> will happily copy entire directory hierarchies
+if you ask it to (similar to B<cp -a>). If it is asked to install a
+directory, it will install the complete contents of the directory.

+
+=head1 DESCRIPTION
+
+B<dh_installinfo> is a debhelper program that is responsible for installing
+info files into F<usr/share/info> in the package build directory.
+
+From debhelper compatibility level 11 on, B<dh_install> will fall back to
+looking in F<debian/tmp> for files, if it does not find them in the current
+directory (or wherever you've told it to look using B<--sourcedir>).
+

+
+=item debian/I<package>.info
+
+List info files to be installed.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.

+
+=item B<-A>, B<--all>
+
+Install all files specified by command line parameters in ALL packages

+
+=item B<--sourcedir=>I<dir>
+
+Look in the specified directory for files to be installed. This option
+requires compat 11 or later (it is silently ignored in compat 10 or earlier).
+
+Note that this is not the same as the B<--sourcedirectory> option used
+by the B<dh_auto_>I<*> commands. You rarely need to use this option, since
+B<dh_installinfo> automatically looks for files in F<debian/tmp> in debhelper
+compatibility level 11 and above.
+
+=item I<file> ...
+
+Install these info files into the first package acted on. (Or in
+all packages if B<-A> is specified).

+B<dh_installinit> [S<I<debhelper options>>] [B<--name=>I<name>] [B<-n>] [B<-R>] [B<-r>] [B<-d>] [S<B<--> I<params>>]
+
+=head1 DESCRIPTION
+
+B<dh_installinit> is a debhelper program that is responsible for
+installing init scripts with associated defaults files. In
+compatibility levels up to and including 10, B<dh_installinit> will
+also install some systemd related files provided by the debian
+packaging (see the L</FILES> section below). In compatibility levels
+up to and including 11, B<dh_installinit> will also handle upstart
+jobs provided in the debian packaging (see the L</FILES> for more
+information on this as well).
+
+It also automatically generates the F<postinst> and F<postrm> and F<prerm>
+commands needed to set up the symlinks in F</etc/rc*.d/> to start and stop
+the init scripts.
+
+In compat 10 or earlier: If a package only ships a systemd service
+file and no sysvinit script is provided, you may want to exclude the
+call to dh_installinit for that package (e.g. via B<-N>). Otherwise,
+you may get warnings from lintian about init.d scripts not being
+included in the package.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.init
+
+If this exists, it is installed into etc/init.d/I<package> in the package
+build directory.
+
+=item debian/I<package>.default
+
+If this exists, it is installed into etc/default/I<package> in the package
+build directory.
+
+=item debian/I<package>.upstart
+
+In compatibility level 11, this file will trigger an error with a reminder
+about ensuring the proper removal of the upstart file in the previous package
+version. Please consider using the "rm_conffile" feature from
+L<dh_installdeb(1)> to ensure the proper removal of previous upstart files.
+
+In compatibility level 10, if this file exists, it is installed into
+etc/init/I<package>.conf in the package build directory.
+
+=item debian/I<package>.service
+
+If this exists, it is installed into F<< lib/systemd/system/I<package>.service >> in
+the package build directory. Only used in compat levels 10 and below.
+
+=item debian/I<package>.tmpfile
+
+If this exists, it is installed into usr/lib/tmpfiles.d/I<package>.conf in the
+package build directory. Only used in compat levels 10 and below.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--no-scripts>
+
+Do not modify F<postinst>/F<postrm>/F<prerm> scripts.
+
+=item B<-o>, B<--only-scripts>
+
+Only modify F<postinst>/F<postrm>/F<prerm> scripts, do not actually install
+any init script, default files, upstart job or systemd service file. May be
+useful if the file is shipped and/or installed by upstream in a way that
+doesn't make it easy to let B<dh_installinit> find it.
+
+B<Caveat>: This will bypass all the regular checks and
+I<unconditionally> modify the scripts. You will almost certainly want
+to use this with B<-p> to limit, which packages are affected by the
+call. Example:
+
+ override_dh_installinit:
+ dh_installinit -pfoo --only-scripts
+ dh_installinit --remaining
+
+=item B<-R>, B<--restart-after-upgrade>
+
+Do not stop the init script until after the package upgrade has been
+completed. This is the default behaviour in compat 10.
+
+In early compat levels, the default was to stop the script in the
+F<prerm>, and starts it again in the F<postinst>.
+
+This can be useful for daemons that should not have a possibly long
+downtime during upgrade. But you should make sure that the daemon will not
+get confused by the package being upgraded while it's running before using
+this option.
+
+=item B<--no-restart-after-upgrade>
+
+Undo a previous B<--restart-after-upgrade> (or the default of compat
+10). If no other options are given, this will cause the service to be
+stopped in the F<prerm> script and started again in the F<postinst>
+script.
+
+=item B<-r>, B<--no-stop-on-upgrade>, B<--no-restart-on-upgrade>
+
+Do not stop init script on upgrade. This has the side-effect of not
+restarting the service as a part of the upgrade.
+
+If you want to restart the service with minimal downtime, please use
+B<--restart-after-upgrade> (default in compat 10 or later). If you want
+the service to be restarted but be stopped during the upgrade, then please
+use B<--no-restart-after-upgrade> (note the "after-upgrade").
+
+Note that the B<--no-restart-on-upgrade> alias is deprecated and will
+be removed in compat 12. This is to avoid confusion with the
+B<--no-restart-after-upgrade> option. The B<--no-stop-on-upgrade>
+variant was introduced in debhelper 10.2 (included in Debian stretch).
+
+=item B<--no-start>
+
+Do not start the init script on install or upgrade, or stop it on removal.
+Only call B<update-rc.d>. Useful for rcS scripts.
+
+=item B<--no-enable>
+
+Disable the init script on purge, but do not enable them on install.
+This implies a versioned dependency on B<< init-system-helpers (E<gt>=
+1.51) >> as it is the first (functional) version that supports
+B<< update-rc.d E<lt>scriptE<gt> defaults-disabled >>.
+
+B<Note> that this option does not affect whether the services are
+started. Please remember to also use B<--no-start> if the service
+should not be started.
+
+Cannot be combined with B<-u>I<params>,
+B<--update-rcd-params=>I<params>, or B<--> I<params>.
+
+=item B<-d>, B<--remove-d>
+
+Remove trailing B<d> from the name of the package, and use the result for the
+filename the upstart job file is installed as in F<etc/init/> , and for the
+filename the init script is installed as in etc/init.d and the default file
+is installed as in F<etc/default/>. This may be useful for daemons with names
+ending in B<d>. (Note: this takes precedence over the B<--init-script> parameter
+described below.)
+
+=item B<-u>I<params> B<--update-rcd-params=>I<params>
+
+=item B<--> I<params>
+
+Pass I<params> to L<update-rc.d(8)>. If not specified, B<defaults> (or
+B<defaults-disabled> with B<--no-enable>) will be passed to
+L<update-rc.d(8)>.
+
+Cannot be combined with B<--no-enable>.
+
+=item B<--name=>I<name>
+
+Install the init script (and default file) as well as upstart job file
+using the filename I<name> instead of the default filename, which is
+the package name. When this parameter is used, B<dh_installinit> looks
+for and installs files named F<debian/package.name.init>,
+F<debian/package.name.default> and F<debian/package.name.upstart>
+instead of the usual F<debian/package.init>, F<debian/package.default> and
+F<debian/package.upstart>.
+
+=item B<--init-script=>I<scriptname>
+
+Use I<scriptname> as the filename the init script is installed as in
+F<etc/init.d/> (and also use it as the filename for the defaults file, if it
+is installed). If you use this parameter, B<dh_installinit> will look to see
+if a file in the F<debian/> directory exists that looks like
+F<package.scriptname> and if so will install it as the init script in
+preference to the files it normally installs.
+
+This parameter is deprecated, use the B<--name> parameter instead. This
+parameter is incompatible with the use of upstart jobs.
+
+=item B<--error-handler=>I<function>
+
+Call the named shell I<function> if running the init script fails. The
+function should be provided in the F<prerm> and F<postinst> scripts, before the
+B<#DEBHELPER#> token.
+
+=back
+
+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.

+=head1 SYNOPSIS
+
+B<dh_installman> [S<I<debhelper options>>] [S<I<manpage> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_installman> is a debhelper program that handles installing man
+pages into the correct locations in package build directories.
+
+In compat 10 and earlier, this program was primarily for when
+upstream's build system does not properly install them as a part of
+its install step (or it does not have an install step). In compat 11
+and later, it also supports the default searchdir plus --sourcedir
+like dh_install(1) and has the advantage that it respects the nodoc
+build profile (unlike dh_install(1)).
+
+Even if you prefer to use L<dh_install(1)> for installing the manpages,
+B<dh_installman> can still be useful for converting the manpage encoding
+to UTF-8 and for converting F<.so> links (as described below). However,
+that part happens automatically without any explicit configuration.
+
+
+You tell B<dh_installman> what man pages go in your packages, and it figures out
+where to install them based on the section field in their B<.TH> or
+B<.Dt> line. If you have a properly formatted B<.TH> or B<.Dt> line,
+your man page will be installed into the right directory, with the
+right name (this includes proper handling of pages with a subsection,
+like B<3perl>, which are placed in F<man3>, and given an extension of
+F<.3perl>). If your B<.TH> or B<.Dt> line is incorrect or missing, the
+program may guess wrong based on the file extension.
+
+It also supports translated man pages, by looking for extensions
+like F<.ll.8> and F<.ll_LL.8>, or by use of the B<--language> switch.
+
+If B<dh_installman> seems to install a man page into the wrong section or with
+the wrong extension, this is because the man page has the wrong section
+listed in its B<.TH> or B<.Dt> line. Edit the man page and correct the
+section, and B<dh_installman> will follow suit. See L<man(7)> for details
+about the B<.TH> section, and L<mdoc(7)> for the B<.Dt> section. If
+B<dh_installman> seems to install a man page into a directory
+like F</usr/share/man/pl/man1/>, that is because your program has a
+name like F<foo.pl>, and B<dh_installman> assumes that means it is translated
+into Polish. Use B<--language=C> to avoid this.
+
+After the man page installation step, B<dh_installman> will check to see if
+any of the man pages in the temporary directories of any of the packages it
+is acting on contain F<.so> links. If so, it changes them to symlinks.
+
+Also, B<dh_installman> will use man to guess the character encoding of each
+manual page and convert it to UTF-8. If the guesswork fails for some
+reason, you can override it using an encoding declaration. See
+L<manconv(1)> for details.
+
+From debhelper compatibility level 11 on, B<dh_install> will fall back to
+looking in F<debian/tmp> for files, if it does not find them in the current
+directory (or wherever you've told it to look using B<--sourcedir>).
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.manpages
+
+Lists man pages to be installed.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-A>, B<--all>
+
+Install all files specified by command line parameters in ALL packages
+acted on.
+
+=item B<--language=>I<ll>
+
+Use this to specify that the man pages being acted on are written in the
+specified language.
+
+=item B<--sourcedir=>I<dir>
+
+Look in the specified directory for files to be installed. This option
+requires compat 11 or later (it is silently ignored in compat 10 or earlier).
+
+Note that this is not the same as the B<--sourcedirectory> option used
+by the B<dh_auto_>I<*> commands. You rarely need to use this option, since
+B<dh_installman> automatically looks for files in F<debian/tmp> in debhelper
+compatibility level 11 and above.
+
+=item I<manpage> ...
+
+Install these man pages into the first package acted on. (Or in all
+packages if B<-A> is specified).
+
+=back
+
+=head1 EXAMPLES
+
+An example F<debian/manpages> file could look like this:
+
+ doc/man/foo.1
+ # Translations
+ doc/man/foo.da.1
+ doc/man/foo.de.1
+ doc/man/foo.fr.1
+ # NB: The following line is considered a polish translation
+ # of "foo.1" (and not a manpage written in perl called "foo.pl")
+ doc/man/foo.pl.1
+ # ...
+
+=head1 NOTES
+
+An older version of this program, L<dh_installmanpages(1)>, is still used
+by some packages, and so is still included in debhelper.
+It is, however, deprecated, due to its counterintuitive and inconsistent
+interface. Use this program instead.

+
+B<dh_installmanpages> is a debhelper program that is responsible for
+automatically installing man pages into F<usr/share/man/>
+in package build directories.
+
+This is a DWIM-style program, with an interface unlike the rest of
+debhelper. It is deprecated, and you are encouraged to use
+L<dh_installman(1)> instead.
+
+B<dh_installmanpages> scans the current directory and all subdirectories for
+filenames that look like man pages. (Note that only real files are looked
+at; symlinks are ignored.) It uses L<file(1)> to verify that the files are
+in the correct format. Then, based on the files' extensions, it installs
+them into the correct man directory.
+
+All filenames specified as parameters will be skipped by B<dh_installmanpages>.
+This is useful if by default it installs some man pages that you do not
+want to be installed.
+
+After the man page installation step, B<dh_installmanpages> will check to see
+if any of the man pages are F<.so> links. If so, it changes them to symlinks.
+
+=head1 OPTIONS

+
+Do not install these files as man pages, even if they look like valid man

+=head1 BUGS
+
+B<dh_installmanpages> will install the man pages it finds into B<all> packages
+you tell it to act on, since it can't tell what package the man
+pages belong in. This is almost never what you really want (use B<-p> to work
+around this, or use the much better L<dh_installman(1)> program instead).
+
+Files ending in F<.man> will be ignored.

+Files specified as parameters that contain spaces in their filenames will
+not be processed properly.

+
+=head1 DESCRIPTION
+
+B<dh_installsystemd> is a debhelper program that is responsible for
+installing package maintainer supplied systemd unit files.
+
+It also finds the service files installed by a package and generates
+F<preinst>, F<postinst>, and F<prerm> code blocks for enabling,
+disabling, starting, stopping, and restarting the corresponding
+systemd services, when the package is installed, updated, or
+removed. These snippets are added to the maintainer scripts by
+L<dh_installdeb(1)>.
+
+L<deb-systemd-helper(1)> is used to enable and disable systemd units,
+thus it is not necessary that the machine actually runs systemd during
+package installation time, enabling happens on all machines in order
+to be able to switch from sysvinit to systemd and back.
+
+B<dh_installsystemd> operates on all unit files installed by a
+package. For only generating blocks for specific unit files, pass them
+as arguments, C<dh_installsystemd quota.service>. Specific unit files
+can be excluded from processing using the B<-X> common L<debhelper(1)>
+option.
+

+

+Only used in compat 12 or earlier. In compat 13+, this file is
+handled by L<dh_installtmpfiles(1)> instead.
+
+If this exists, it is installed into F<usr/lib/tmpfiles.d/> in the
+package build directory. Note that the C<tmpfiles.d> mechanism is
+currently only used by systemd.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--no-enable>
+
+Disable the service(s) on purge, but do not enable them on install.
+
+B<Note> that this option does not affect whether the services are
+started. Please remember to also use B<--no-start> if the service
+should not be started.
+
+=item B<--name=>I<name>
+
+This option controls several things.
+
+It changes the name that B<dh_installsystemd> uses when it looks for
+maintainer provided systemd unit files as listed in the L</FILES>
+section. As an example, B<dh_installsystemd --name foo> will look for
+F<<< I<debian/package.>B<< I<foo> >>I<.service> >>> instead of
+F<< I<debian/package.service> >>). These unit files are installed as F<<
+I<name.unit-extension> >> (in the example, it would be installed as
+F<<< B<< I<foo> >>I<.service> >>>).
+
+Furthermore, if no unit files are passed explicitly as command line
+arguments, B<dh_installsystemd> will only act on unit files called
+I<name> (rather than all unit files found in the package).
+
+=item B<--restart-after-upgrade>
+
+Do not stop the unit file until after the package upgrade has been completed.
+This is the default behaviour in compat 10.
+
+In earlier compat levels the default was to stop the unit file in the
+F<prerm>, and start it again in the F<postinst>.
+
+This can be useful for daemons that should not have a possibly long
+downtime during upgrade. But you should make sure that the daemon will not
+get confused by the package being upgraded while it's running before using
+this option.
+
+=item B<--no-restart-after-upgrade>
+
+Undo a previous B<--restart-after-upgrade> (or the default of compat
+10). If no other options are given, this will cause the service to be
+stopped in the F<prerm> script and started again in the F<postinst>
+script.
+
+=item B<-r>, B<--no-stop-on-upgrade>, B<--no-restart-on-upgrade>
+
+Do not stop service on upgrade. This has the side-effect of not
+restarting the service as a part of the upgrade.
+
+If you want to restart the service with minimal downtime, please use
+B<--restart-after-upgrade> (default in compat 10 or later). If you want
+the service to be restarted but be stopped during the upgrade, then please
+use B<--no-restart-after-upgrade> (note the "after-upgrade").
+
+Note that the B<--no-restart-on-upgrade> alias is deprecated and will
+be removed in compat 14. This is to avoid confusion with the
+B<--no-restart-after-upgrade> option.
+
+=item B<--no-start>
+
+Do not start the unit file after upgrades and after initial installation (the
+latter is only relevant for services without a corresponding init script).
+
+B<Note> that this option does not affect whether the services are
+enabled. Please remember to also use B<--no-enable> if the services
+should not be enabled.
+
+=item S<B<unit file> ...>
+
+Only process and generate maintscripts for the installed unit files
+with the (base)name I<unit file>.
+
+Note: B<dh_installsystemd> will still install unit files from
+F<debian/> but it will not generate any maintscripts for them unless
+they are explicitly listed in S<B<unit file> ...>
+

+This command is not idempotent. L<dh_prep(1)> should be called between

+
+B<dh_installsystemduser> [S<I<debhelper options>>] [B<--no-enable>] [B<--name=>I<name>] [S<I<unit file> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_installsystemduser> finds the systemd user instance service files
+installed by a package and generates F<preinst>, F<postinst>, and F<prerm>
+code blocks for enabling, disabling, starting, stopping, and restarting the
+corresponding systemd user instance services, when the package is installed,
+updated, or removed. These snippets are added to the maintainer scripts by
+L<dh_installdeb(1)>.
+
+L<deb-systemd-helper(1)> is used to enable and disable the systemd
+units, thus it is not necessary that the machine actually runs systemd
+during package installation time, enabling happens on all machines.
+
+B<dh_installsystemduser> operates on all user instance unit files
+installed by a package. For only generating blocks for specific unit
+files, pass them as arguments. Specific unit files can be excluded
+from processing using the B<-X> common L<debhelper(1)> option.

+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--name=>I<name>
+
+Install the service file as I<name.service> instead of the default
+filename I<package.service>. When this parameter is used,
+B<dh_installsystemd> looks for and installs files named
+F<debian/package.name.user.service> instead of the usual
+F<debian/package.user.service>. Moreover, maintainer scripts are only
+generated for units that match the given I<name>.
+
+=item B<--no-enable>
+
+Disable the service(s) on purge, but do not enable them on install.
+
+=back
+
+=head1 NOTES
+
+This command is not idempotent. L<dh_prep(1)> should be called between
+invocations of this command (with the same arguments). Otherwise, it
+may cause multiple instances of the same text to be added to
+maintainer scripts.

+
+B<dh_installxfonts> is a debhelper program that is responsible for
+registering X fonts, so their corresponding F<fonts.dir>, F<fonts.alias>,
+and F<fonts.scale> be rebuilt properly at install time.
+
+Before calling this program, you should have installed any X fonts provided
+by your package into the appropriate location in the package build
+directory, and if you have F<fonts.alias> or F<fonts.scale> files, you should
+install them into the correct location under F<etc/X11/fonts> in your
+package build directory.
+
+Your package should depend on B<xfonts-utils> so that the
+B<update-fonts->I<*> commands are available. (This program adds that dependency to
+B<${misc:Depends}>.)
+
+This program automatically generates the F<postinst> and F<postrm> commands needed
+to register X fonts. These commands are inserted into the maintainer
+scripts by B<dh_installdeb>. See L<dh_installdeb(1)> for an explanation of how
+this works.
+
+=head1 NOTES
+
+See L<update-fonts-alias(8)>, L<update-fonts-scale(8)>, and
+L<update-fonts-dir(8)> for more information about X font installation.
+
+See Debian policy, section 11.8.5. for details about doing fonts the Debian
+way.

+
+=head1 DESCRIPTION
+
+B<dh_link> is a debhelper program that creates symlinks in package build
+directories.
+
+B<dh_link> accepts a list of pairs of source and destination
+files. The source files are the already existing files that will be
+symlinked from (called B<target> by L<ln(1)>). The destination files
+are the symlinks that will be created (called B<link name> by
+L<ln(1)>). There B<must> be an equal number of source and destination
+files specified.
+
+Be sure you B<do> specify the absolute path to both the source and
+destination files (unlike you would do if you were using something
+like L<ln(1)>). Please note that the leading slash is optional.
+
+B<dh_link> will generate symlinks that comply with Debian policy - absolute
+when policy says they should be absolute, and relative links with as short
+a path as possible. It will also create any subdirectories it needs to put
+the symlinks in.
+
+Any pre-existing destination files will be replaced with symlinks.
+
+B<dh_link> also scans the package build tree for existing symlinks which do not
+conform to Debian policy, and corrects them (v4 or later).
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.links
+
+Lists pairs of source and destination files to be symlinked. Each pair
+should be put on its own line, with the source and destination separated by
+whitespace.
+
+In each pair the source file (called B<target> by L<ln(1)>) comes
+first and is followed by the destination file (called B<link name> by
+L<ln(1)>). Thus the pairs of source and destination files in each line
+are given in the same order as they would be given to L<ln(1)>.
+
+In contrast to L<ln(1)>, source and destination paths must be absolute
+(the leading slash is optional).

+
+=head1 DESCRIPTION
+
+B<dh_makeshlibs> is a debhelper program that automatically scans for shared
+libraries, and generates a shlibs file for the libraries it finds.
+
+It will also ensure that ldconfig is invoked during install and removal when
+it finds shared libraries. Since debhelper 9.20151004, this is done via a
+dpkg trigger. In older versions of debhelper, B<dh_makeshlibs> would
+generate a maintainer script for this purpose.
+
+Since debhelper 12.3, B<dh_makeshlibs> will by default add an additional
+I<udeb> line for udebs in the shlibs file, when the udeb has the same
+name as the deb followed by a "-udeb" suffix (e.g. if the deb is called
+"libfoo1", then debhelper will auto-detect the udeb if it is named
+"libfoo1-udeb"). Please use the B<--add-udeb> and B<--no-add-udeb> options
+below when this auto-detection is insufficient.
+
+If you previously used B<--add-udeb> and are considering to migrate to
+using the new auto-detection feature in 12.3, then
+please remember to test that the resulting F<DEBIAN/shlibs> files are
+as expected. There are some known corner cases, where the
+auto-detection is insufficient. These include when the udeb contains
+library files from multiple regular deb packages or when the packages
+do not follow the expected naming convention.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.shlibs
+
+Installs this file, if present, into the package as DEBIAN/shlibs. If
+omitted, debhelper will generate a shlibs file automatically if it
+detects any libraries.
+
+Note in compat levels 9 and earlier, this file was installed by
+L<dh_installdeb(1)> rather than B<dh_makeshlibs>.
+
+=item debian/I<package>.symbols
+
+=item debian/I<package>.symbols.I<arch>
+
+These symbols files, if present, are passed to L<dpkg-gensymbols(1)> to
+be processed and installed. Use the I<arch> specific names if you need
+to provide different symbols files for different architectures.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-m>I<major>, B<--major=>I<major>
+
+Instead of trying to guess the major number of the library with objdump,
+use the major number specified after the -m parameter. This is much less
+useful than it used to be, back in the bad old days when this program
+looked at library filenames rather than using objdump.
+
+=item B<-V>, B<-V>I<dependencies>
+
+=item B<--version-info>, B<--version-info=>I<dependencies>
+
+If a shlibs file is generated by this program, this option controls
+what version will be used in the dependency relation.
+
+In compat 12 and later, B<dh_makeshlibs> defaults to B<-VUpstream-Version>.
+In compat 11 and earlier the default behaved like B<-VNone>.
+
+The B<dh_makeshlibs> tool can generate dependencies in three variants:
+
+=over 4
+
+=item B<-VUpstream-Version>
+
+The dependency will be "I<packagename> B<(E<gt>>= I<packageversion>B<)>".
+Note that I<Upstream-Version> is case-sensitive and must be written
+exactly as shown here.
+
+This is a conservative setting that always ensures that other packages'
+shared library dependencies are at least as tight as they need to be
+(unless the library is prone to changing ABI without updating the
+upstream version number).
+
+The flip side is that packages might end up with dependencies that are
+too tight in some cases (note a symbols file can mitigate this issue).
+This is often of minor temporary inconvenience and usually a lot
+better than the fall out caused by forgetting to bump the dependency
+information.
+
+This explicit form was added in debhelper/11.3. In previous versions,
+a B<-V> without any dependency information was used instead (and that
+form still works)
+
+=item B<-VNone>
+
+The dependency will be "I<packagename>". Note that I<None> is
+case-sensitive and must be written exactly as shown here.
+
+This form is generally unsafe with the only exception being if upstream
+does not extend the ABI in any way. However, most upstreams improve their
+interfaces over time and packagers are recommended to use
+B<-VUpstream-Version> (or one of the other forms of B<-V>I<dependencies>).
+
+Alternatively, this may be sufficient if (and only if) the package uses
+symbol versioning (see L<dpkg-gensymbols(1)>) and does I<not> build any
+udeb packages. Note that symbols are not supported for udeb packages,
+which solely relies on shlibs for dependency handling.
+
+=item B<-V>I<package-relation>
+
+In this case, the value passed to B<-V> will be used as a dependency
+relation. The I<package-relation> should generally be of the form
+"I<some-package-name> B<(E<gt>>= I<some-package-version>B<)>". Remember
+to include the package name.
+
+Note that debhelper will use the value I<as it is> with no sanity
+checking or modification. In I<rare special> cases, this is needed to
+generate a dependency on a different package than the one containing
+the library.

+When choosing a value for this option, please keep mind that if the

+
+=item B<-n>, B<--no-scripts>
+
+Do not add the "ldconfig" trigger even if it seems like the package
+might need it. The option is called B<--no-scripts> for historical
+reasons as B<dh_makeshlibs> would previously generate maintainer
+scripts that called B<ldconfig>.
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename or directory
+from being treated as shared libraries.
+
+=item B<--add-udeb=>I<udeb>
+
+Create an additional line for udebs in the shlibs file and use I<udeb> as the
+package name for udebs to depend on instead of the regular library package.
+
+This option is only useful for special cases such as when debhelper
+cannot auto-detect package name of the udeb package, when the udeb
+will contain libraries from multiple deb packages, or when the udeb
+contains libraries B<not> present in the deb package.
+
+=item B<--no-add-udeb>
+
+Do not add any udeb lines to the shlibs file. This can be used to disable the
+default auto-detection of udebs.
+
+This may be useful in case you do not want a shlibs file at all for the udeb
+because no package will depend on it. E.g. because adding a udeb package
+for the library was "overkill" and the library is embedded in a different
+udeb package.

+These files are used by B<dpkg --verify> or the L<debsums(1)> program.
+
+All files in F<DEBIAN/> are omitted from the F<md5sums> file, as are all

+=head1 SYNOPSIS
+
+B<dh_missing> [B<-X>I<item>] [B<--sourcedir=>I<dir>] [S<I<debhelper options>>]
+
+=head1 DESCRIPTION
+
+B<dh_missing> compares the list of installed files with the files in
+the source directory. If any of the files (and symlinks) in the source
+directory were not installed to somewhere, it will warn on stderr
+about that (B<--list-missing>) or fail (B<--fail-missing>).
+
+Please note that in compat 11 and earlier without either of these
+options, B<dh_missing> will silently do nothing. In compat 12,
+B<--list-missing> is the default In compat 13 and later,
+B<--fail-missing> is the default.
+
+This may be useful if you have a large package and want to make sure that
+you don't miss installing newly added files in new upstream releases.
+
+Remember to test different kinds of builds (dpkg-buildpackage -A/-B/...) as
+you may experience varying results when only a subset of the packages are
+built.
+
+=head1 FILES
+
+=over 4
+
+=item debian/not-installed
+
+List the files that are deliberately not installed in I<any> binary
+package. Paths listed in this file are ignored by B<dh_missing>.
+However, it is B<not> a method to exclude files from being installed
+by any of the debhelper tool. If you want a tool to not install a
+given file, please use its B<--exclude> option (where available).
+
+B<dh_missing> will expand wildcards in this file (since debhelper 11.1).
+Wildcards without matches will be ignored.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--list-missing>
+
+Warn on stderr about source files not installed to somewhere.
+
+Note that many dh-tools acting on a path will mark the path as
+installed even if it has been excluded via B<-X> or B<--exclude>.
+This is also seen when a dh-tool is acting on a directory and
+exclusion is used to ignore some files in the directory. In either
+case, this will make B<dh_missing> silently assume the excluded files
+have been handled.
+
+This is the default in compat 12.
+
+=item B<--fail-missing>
+
+This option is like B<--list-missing>, except if a file was missed, it will
+not only list the missing files, but also fail with a nonzero exit code.

+
+B<dh_movefiles> [S<I<debhelper options>>] [B<--sourcedir=>I<dir>] [B<-X>I<item>] [S<I<file> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_movefiles> is a debhelper program that is responsible for moving files
+out of F<debian/tmp> or some other directory and into other package build
+directories. This may be useful if your package has a F<Makefile> that installs
+everything into F<debian/tmp>, and you need to break that up into subpackages.
+
+Note: B<dh_install> is a much better program, and you are recommended to use
+it instead of B<dh_movefiles>.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.files
+
+Lists the files to be moved into a package, separated by whitespace. The
+filenames listed should be relative to F<debian/tmp/>. You can also list
+directory names, and the whole directory will be moved.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--sourcedir=>I<dir>
+
+Instead of moving files out of F<debian/tmp> (the default), this option makes
+it move files out of some other directory. Since the entire contents of
+the sourcedir is moved, specifying something like B<--sourcedir=/> is very
+unsafe, so to prevent mistakes, the sourcedir must be a relative filename;
+it cannot begin with a `B</>'.
+
+=item B<-Xitem>, B<--exclude=item>
+
+Exclude files that contain B<item> anywhere in their filename from
+being installed.
+
+=item I<file> ...
+
+Lists files to move. The filenames listed should be relative to
+F<debian/tmp/>. You can also list directory names, and the whole directory will
+be moved. It is an error to list files here unless you use B<-p>, B<-i>, or B<-a> to
+tell B<dh_movefiles> which subpackage to put them in.
+
+=back
+
+=head1 NOTES
+
+Note that files are always moved out of F<debian/tmp> by default (even if you
+have instructed debhelper to use a compatibility level higher than one,
+which does not otherwise use debian/tmp for anything at all). The idea
+behind this is that the package that is being built can be told to install
+into F<debian/tmp>, and then files can be moved by B<dh_movefiles> from that
+directory. Any files or directories that remain are ignored, and get
+deleted by B<dh_clean> later.

+
+B<dh_perl> [S<I<debhelper options>>] [B<-d>] [S<I<library dirs> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_perl> is a debhelper program that is responsible for generating
+the B<${perl:Depends}> substitutions and adding them to substvars files.
+
+The program will look at Perl scripts and modules in your package,
+and will use this information to generate a dependency on B<perl> or
+B<perlapi>. The dependency will be substituted into your package's F<control>
+file wherever you place the token B<${perl:Depends}>.
+
+B<dh_perl> also cleans up empty directories that MakeMaker can generate when
+installing Perl modules.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-d>
+
+In some specific cases you may want to depend on B<perl-base> rather than the
+full B<perl> package. If so, you can pass the -d option to make B<dh_perl> generate
+a dependency on the correct base package. This is only necessary for some
+packages that are included in the base system.
+
+Note that this flag may cause no dependency on B<perl-base> to be generated at
+all. B<perl-base> is Essential, so its dependency can be left out, unless a
+versioned dependency is needed.
+
+=item B<-V>
+
+By default, scripts and architecture independent modules don't depend
+on any specific version of B<perl>. The B<-V> option causes the current
+version of the B<perl> (or B<perl-base> with B<-d>) package to be specified.
+
+=item I<library dirs>
+
+If your package installs Perl modules in non-standard
+directories, you can make B<dh_perl> check those directories by passing their
+names on the command line. It will only check the F<vendorlib> and F<vendorarch>
+directories by default.

+
+=head1 DESCRIPTION
+
+B<dh_shlibdeps> is a debhelper program that is responsible for calculating
+shared library dependencies for packages.
+
+This program is merely a wrapper around L<dpkg-shlibdeps(1)> that calls it
+once for each package listed in the F<control> file, passing it
+a list of ELF executables and shared libraries it has found.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain F<item> anywhere in their filename from being
+passed to B<dpkg-shlibdeps>. This will make their dependencies be ignored.
+This may be useful in some situations, but use it with caution. This option
+may be used more than once to exclude more than one thing.
+
+=item B<--> I<params>
+
+Pass I<params> to L<dpkg-shlibdeps(1)>.
+
+=item B<-u>I<params>, B<--dpkg-shlibdeps-params=>I<params>
+
+This is another way to pass I<params> to L<dpkg-shlibdeps(1)>.
+It is deprecated; use B<--> instead.
+
+=item B<-l>I<directory>[B<:>I<directory> ...]
+
+With recent versions of B<dpkg-shlibdeps>, this option is generally not
+needed.
+
+It tells B<dpkg-shlibdeps> (via its B<-l> parameter), to look for private
+package libraries in the specified directory (or directories -- separate
+with colons). With recent
+versions of B<dpkg-shlibdeps>, this is mostly only useful for packages that
+build multiple flavors of the same library, or other situations where
+the library is installed into a directory not on the regular library search
+path.
+
+=item B<-L>I<package>, B<--libpackage=>I<package>
+
+With recent versions of B<dpkg-shlibdeps>, this option is generally not
+needed, unless your package builds multiple flavors of the same library
+or is relying on F<debian/shlibs.local> for an internal library.
+
+It tells B<dpkg-shlibdeps> (via its B<-S> parameter) to look first in the package
+build directory for the specified package, when searching for libraries,
+symbol files, and shlibs files.
+
+If needed, this can be passed multiple times with different package
+names.
+
+=back
+
+=head1 EXAMPLES
+
+Suppose that your source package produces libfoo1, libfoo-dev, and
+libfoo-bin binary packages. libfoo-bin links against libfoo1, and should
+depend on it. In your rules file, first run B<dh_makeshlibs>, then B<dh_shlibdeps>:
+
+ dh_makeshlibs
+ dh_shlibdeps
+
+This will have the effect of generating automatically a shlibs file for
+libfoo1, and using that file and the libfoo1 library in the
+F<debian/libfoo1/usr/lib> directory to calculate shared library dependency
+information.
+
+If a libbar1 package is also produced, that is an alternate build of
+libfoo, and is installed into F</usr/lib/bar/>, you can make libfoo-bin depend
+on libbar1 as follows:
+
+ dh_shlibdeps -Llibbar1 -l/usr/lib/bar

+
+B<dh_strip> [S<I<debhelper options>>] [B<-X>I<item>] [B<--dbg-package=>I<package>] [B<--keep-debug>]
+
+=head1 DESCRIPTION
+
+B<dh_strip> is a debhelper program that is responsible for stripping
+out debug symbols in executables, shared libraries, and static
+libraries that are not needed during execution.
+
+This program examines your package build directories and works out what
+to strip on its own. It uses L<file(1)> and file permissions and filenames
+to figure out what files are shared libraries (F<*.so>), executable binaries,
+and static (F<lib*.a>) and debugging libraries (F<lib*_g.a>, F<debug/*.so>), and
+strips each as much as is possible. (Which is not at all for debugging
+libraries.) In general it seems to make very good guesses, and will do the
+right thing in almost all cases.
+
+Since it is very hard to automatically guess if a file is a
+module, and hard to determine how to strip a module, B<dh_strip> does not
+currently deal with stripping binary modules such as F<.o> files.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename from being
+stripped. You may use this option multiple times to build up a list of
+things to exclude.
+
+=item B<--dbg-package=>I<package>
+
+B<This option is a now special purpose option that you normally do not
+need>. In most cases, there should be little reason to use this
+option for new source packages as debhelper automatically generates
+debug packages ("dbgsym packages"). B<If you have a manual
+--dbg-package> that you want to replace with an automatically
+generated debug symbol package, please see the B<--dbgsym-migration>
+option.
+
+Causes B<dh_strip> to save debug symbols stripped from the packages it acts on
+as independent files in the package build directory of the specified debugging
+package.
+
+For example, if your packages are libfoo and foo and you want to include a
+I<foo-dbg> package with debugging symbols, use B<dh_strip --dbg-package=>I<foo-dbg>.
+
+This option implies B<--no-automatic-dbgsym> and I<cannot> be used
+with B<--automatic-dbgsym> or B<--dbgsym-migration>.
+
+=item B<-k>, B<--keep-debug>
+
+B<This option is a now special purpose option that you normally do not
+need>. In most cases, there should be little reason to use this
+option for new source packages as debhelper automatically generates
+debug packages ("dbgsym packages"). B<If you have a manual
+--dbg-package> that you want to replace with an automatically
+generated debug symbol package, please see the B<--dbgsym-migration>
+option.
+
+Debug symbols will be retained, but split into an independent
+file in F<usr/lib/debug/> in the package build directory. B<--dbg-package>
+is easier to use than this option, but this option is more flexible.
+
+This option implies B<--no-automatic-dbgsym> and I<cannot> be used
+with B<--automatic-dbgsym>.
+
+=item B<--dbgsym-migration=>I<package-relation>
+
+This option is used to migrate from a manual "-dbg" package (created
+with B<--dbg-package>) to an automatic generated debug symbol
+package. This option should describe a valid B<Replaces>- and
+B<Breaks>-relation, which will be added to the debug symbol package to
+avoid file conflicts with the (now obsolete) -dbg package.
+
+This option implies B<--automatic-dbgsym> and I<cannot> be used with
+B<--keep-debug>, B<--dbg-package> or B<--no-automatic-dbgsym>.
+
+Examples:
+
+ dh_strip --dbgsym-migration='libfoo-dbg (<< 2.1-3~)'
+
+ dh_strip --dbgsym-migration='libfoo-tools-dbg (<< 2.1-3~), libfoo2-dbg (<< 2.1-3~)'
+
+=item B<--automatic-dbgsym>, B<--no-automatic-dbgsym>
+
+Control whether B<dh_strip> should be creating debug symbol packages
+when possible.
+
+The default is to create debug symbol packages.
+
+=item B<--ddebs>, B<--no-ddebs>
+
+Historical name for B<--automatic-dbgsym> and B<--no-automatic-dbgsym>.
+
+=item B<--ddeb-migration=>I<package-relation>
+
+Historical name for B<--dbgsym-migration>.
+
+=back
+
+=head1 NOTES
+
+If the B<DEB_BUILD_OPTIONS> environment variable contains B<nostrip>,
+nothing will be stripped, in accordance with Debian policy (section
+10.1 "Binaries"). This will also inhibit the automatic creation of
+debug symbol packages.
+
+The automatic creation of debug symbol packages can also be prevented
+by adding B<noautodbgsym> to the B<DEB_BUILD_OPTIONS> environment
+variable. However, B<dh_strip> will still add debuglinks to ELF
+binaries when this flag is set. This is to ensure that the regular
+deb package will be identical with and without this flag (assuming it
+is otherwise "bit-for-bit" reproducible).

+B<dh_systemd_enable> [S<I<debhelper options>>] [B<--no-enable>] [B<--name=>I<name>] [S<I<unit file> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_systemd_enable> is a debhelper program that is responsible for enabling
+and disabling systemd unit files.
+
+In the simple case, it finds all unit files installed by a package (e.g.
+bacula-fd.service) and enables them. It is not necessary that the machine
+actually runs systemd during package installation time, enabling happens on all
+machines in order to be able to switch from sysvinit to systemd and back.
+
+In the complex case, you can call B<dh_systemd_enable> and B<dh_systemd_start>
+manually (by overwriting the debian/rules targets) and specify flags per unit
+file. An example is colord, which ships colord.service, a dbus-activated
+service without an [Install] section. This service file cannot be enabled or
+disabled (a state called "static" by systemd) because it has no
+[Install] section. Therefore, running dh_systemd_enable does not make sense.
+
+For only generating blocks for specific service files, you need to pass them as
+arguments, e.g. B<dh_systemd_enable quota.service> and B<dh_systemd_enable
+--name=quotarpc quotarpc.service>.

+
+=item B<--no-enable>
+
+Disable the service(s) on purge, but do not enable them on install.
+
+B<Note> that this option does not affect whether the services are

+B<--no-start> option).
+
+=item B<--name=>I<name>
+
+Install the service file as I<name.service> instead of the default filename,
+which is the I<package.service>. When this parameter is used,
+B<dh_systemd_enable> looks for and installs files named
+F<debian/package.name.service> instead of the usual F<debian/package.service>.

+
+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command (with the same arguments). Otherwise, it
+may cause multiple instances of the same text to be added to maintainer
+scripts.
+
+Note that B<dh_systemd_enable> should be run before B<dh_installinit>.

+
+B<dh_systemd_start> [S<I<debhelper options>>] [B<--restart-after-upgrade>] [B<--no-stop-on-upgrade>] [S<I<unit file> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_systemd_start> is a debhelper program that is responsible for
+starting/stopping or restarting systemd unit files in case no corresponding
+sysv init script is available.
+
+As with B<dh_installinit>, the unit file is stopped before
+upgrades and started afterwards (unless B<--restart-after-upgrade> is
+specified, in which case it will only be restarted after the upgrade).
+This logic is not used when there is a corresponding SysV init script
+because invoke-rc.d performs the stop/start/restart in that case.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--restart-after-upgrade>
+
+Do not stop the unit file until after the package upgrade has been completed.
+This is the default behaviour in compat 10.
+
+In earlier compat levels the default was to stop the unit file in the
+F<prerm>, and start it again in the F<postinst>.
+
+This can be useful for daemons that should not have a possibly long
+downtime during upgrade. But you should make sure that the daemon will not
+get confused by the package being upgraded while it's running before using
+this option.
+
+=item B<--no-restart-after-upgrade>
+
+Undo a previous B<--restart-after-upgrade> (or the default of compat
+10). If no other options are given, this will cause the service to be
+stopped in the F<prerm> script and started again in the F<postinst>
+script.
+
+=item B<-r>, B<--no-stop-on-upgrade>, B<--no-restart-on-upgrade>
+
+Do not stop service on upgrade.
+
+=item B<--no-start>
+
+Do not start the unit file after upgrades and after initial installation (the
+latter is only relevant for services without a corresponding init script).
+
+=back
+
+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command (with the same arguments). Otherwise, it
+may cause multiple instances of the same text to be added to maintainer
+scripts.
+
+Note that B<dh_systemd_start> should be run after B<dh_installinit> so that it
+can detect corresponding SysV init scripts. The default sequence in B<dh> does
+the right thing, this note is only relevant when you are calling
+B<dh_systemd_start> manually.

+B<dh_testroot> [S<I<debhelper options>>]
+
+=head1 DESCRIPTION
+
+B<dh_testroot> is used to determine if the target is being run with
+suffient access to root(-like) features.
+
+The definition of sufficient access depends on whether the builder
+(the tool invoking the F<debian/rules> target) supports the
+I<Rules-Requires-Root> (R³) field. If the builder supports R³, then
+it will set the environment variable I<DEB_RULES_REQUIRES_ROOT> and
+B<dh_testroot> will validate that the builder followed the minimum
+requirements for the given value of I<DEB_RULES_REQUIRES_ROOT>.
+
+If the builder does not support I<Rules-Requires-Root>, then it will
+not set the I<DEB_RULES_REQUIRES_ROOT> environment variable. This
+will in turn make B<dh_testroot> (and the rest of debhelper) fall back
+to assuming that (fake)root is implied.
+
+The following is a summary of how B<dh_testroot> behaves based on the
+I<DEB_RULES_REQUIRES_ROOT> environment variable (leading and trailing
+whitespace in the variable is ignored).
+
+=over 4
+
+=item -
+
+If unset, or set to C<binary-targets>, then B<dh_testroot> asserts
+that it is run as root or under L<fakeroot(1)>.

+
+If set to C<no>, then B<dh_testroot> returns successfully (without
+performing any additional checks).
+
+=item -
+
+If set to any other value than the above, then B<dh_testroot> asserts
+that it is either run as root (or under L<fakeroot(1)>) or the builder
+has provided the B<DEB_GAIN_ROOT_CMD> environment variable (e.g. via
+dpkg-buildpackage -r).
+
+=back
+
+Please note that B<dh_testroot> does I<not> read the
+I<Rules-Requires-Root> field. Which implies that B<dh_testroot> may
+produce incorrect result if the builder lies in
+I<DEB_RULES_REQUIRES_ROOT>. On the flip side, it also enables things
+like testing for what will happen when I<DEB_RULES_REQUIRES_ROOT> is

+=head1 SYNOPSIS
+
+B<dh_usrlocal> [S<I<debhelper options>>] [B<-n>]
+
+=head1 DESCRIPTION
+
+B<dh_usrlocal> is a debhelper program that can be used for building packages
+that will provide a subdirectory in F</usr/local> when installed.
+
+It finds subdirectories of F<usr/local> in the package build directory, and
+removes them, replacing them with maintainer script snippets (unless B<-n>
+is used) to create the directories at install time, and remove them when
+the package is removed, in a manner compliant with Debian policy. These
+snippets are inserted into the maintainer scripts by B<dh_installdeb>. See
+L<dh_installdeb(1)> for an explanation of debhelper maintainer script
+snippets.
+
+When the I<DEB_RULES_REQUIRES_ROOT> environment variable is not (effectively)
+I<binary-targets>, the directories in F</usr/local> will be handled as if
+they were owned by root:root (see below).
+
+When the I<DEB_RULES_REQUIRES_ROOT> environment variable has an effective value of
+I<binary-targets>, the owners, groups and permissions will be
+preserved with the sole exception where the directory is owned by root:root.
+
+If a directory is owned by root:root, then ownership will be determined
+at install time. The ownership and permission bits will either be root:root
+mode 0755 or root:staff mode 02775. The actual choice depends on whether
+the system has F</etc/staff-group-for-usr-local> (as documented in the Debian
+Policy Manual §9.1.2 since version 4.1.4)

+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
