+=head1 NAME
+
+mk-build-deps - build a package satisfying a package's build-dependencies
+
+=head1 SYNOPSIS
+
+B<mk-build-deps> B<--help>|B<--version>
+
+B<mk-build-deps> [I<options>] I<control file> | I<package name> ...
+
+=head1 DESCRIPTION
+
+Given a I<package name> and/or I<control file>, B<mk-build-deps>
+will use B<equivs> to generate a binary package which may be installed to
+satisfy all the build dependencies of the given package.
+
+If B<--build-dep> and/or B<--build-indep> are given, then the resulting binary
+package(s) will depend solely on the Build-Depends/Build-Depends-Indep
+dependencies, respectively.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-i>, B<--install>
+
+Install the generated packages and its build-dependencies.
+
+=item B<-t>, B<--tool>
+
+When installing the generated package use the specified tool.
+(default: B<apt-get -o Debug::pkgProblemResolver=yes --no-install-recommends>)
+
+=item B<-r>, B<--remove>
+
+Remove the package file after installing it. Ignored if used without
+the B<--install> switch.
+
+=item B<-a> I<foo>, B<--arch> I<foo>
+
+Set the architecture of the produced binary package to I<foo>. If this option
+is not given, fall back to the value given by B<--host-arch>. If neither this
+option nor B<--host-arch> are given but the Build-Depends contain architecture
+restrictions, use the value printed by `dpkg-architecture -qDEB_HOST_ARCH`.
+Otherwise, use I<all>.
+
+The package architecture must be equal to the host architecture except if the
+package architecture is I<all>.
+
+The package architecture cannot be I<all> if the build and host architecture
+differ.
+
+=item B<--host-arch> I<foo>
+
+Set the host architecture the binary package is built for. This defaults to
+the value printed by `dpkg-architecture -qDEB_HOST_ARCH`. Use this option to
+create a binary package that is able to satisfy crossbuild dependencies.
+
+If this option is used together with B<--arch>, then they must be equal except
+if the value of B<--arch> is I<all>.
+
+If B<--arch> is not given, then this option also sets the package architecture.
+
+=item B<--build-arch> I<foo>
+
+Set the build architecture the binary package is built for. This defaults to
+the value printed by `dpkg-architecture -qDEB_BUILD_ARCH`. Use this option to
+create a binary package that is able to satisfy crossbuild dependencies.
+
+=item B<-B>, B<--build-dep>
+
+Generate a package which only depends on the source package's Build-Depends
+dependencies.
+
+=item B<-A>, B<--build-indep>
+
+Generate a package which only depends on the source package's
+Build-Depends-Indep dependencies.
+
+=item B<-P>, B<--build-profiles> I<profile[,...]>
+
+Generate a package which only depends on build dependencies
+with the build profile(s), given as a comma-separated list.
+The default behavior is to use no specific profile.
+Setting this option will override the B<DEB_BUILD_PROFILES>
+environment variable.
+
+=item B<-h>, B<--help>
+
+Show a summary of options.
+
+=item B<-v>, B<--version>
+
+Show version and copyright information.
+
+=item B<-s>, B<--root-cmd>
+
+Use the specified tool to gain root privileges before installing.
+Ignored if used without the B<--install> switch.
+
+=back
+
+=head1 ENVIRONMENT
+
+=head2 External environment
+
+=over 4
+
+=item B<DEB_BUILD_PROFILES>
+
+If set, it will be used as the active build profile(s) for the
+build dependencies to be installed.
+It is a space separated list of profile names.
+Overridden by the B<-P> option.
