+.SH NAME
+dpkg\-architecture \- set and determine the architecture for package building
+.
+.SH SYNOPSIS
+.B dpkg\-architecture
+.RI [ option "...] [" command ]
+.PP
+.
+.SH DESCRIPTION
+.B dpkg\-architecture
+provides a facility to determine and set the build and
+host architecture for package building.
+.PP
+The build architecture is always determined by an external call to
+\fBdpkg\fP(1), and cannot be set at the command line.
+.PP
+You can specify the host architecture by providing one or both of the options
+\fB\-\-host\-arch\fR and \fB\-\-host\-type\fR. The default is determined by
+an external call to
+.BR gcc (1),
+or the same as the build architecture if \fBCC\fP or gcc are both not
+available. One out of \fB\-\-host\-arch\fR and \fB\-\-host\-type\fR is
+sufficient, the value of the
+other will be set to a usable default. Indeed, it is often better to only
+specify one, because \fBdpkg\-architecture\fP will warn you if your choice
+does not match the default.
+.
+.SH COMMANDS
+.TP
+.BR \-l ", " \-\-list
+Print the environment variables, one each line, in the format
+\fIVARIABLE=value\fP. This is the default action.
+.TP
+.BR \-e ", " \-\-equal " \fIarchitecture\fP"
+Check for equality of architecture (since dpkg 1.13.13).
+It compares the current or specified Debian host architecture against
+\fIarchitecture\fP, to check if they are equal.
+This action will not expand the architecture wildcards.
+Command finishes with an exit status of 0 if matched, 1 if not matched.
+
+.TP
+.BR \-i ", " \-\-is " \fIarchitecture-wildcard\fP"
+Check for identity of architecture (since dpkg 1.13.13).
+It compares the current or specified Debian host architecture against
+\fIarchitecture-wildcard\fP after having expanded it as an architecture
+wildcard, to check if they match.
+Command finishes with an exit status of 0 if matched, 1 if not matched.
+.TP
+.BR \-q ", " \-\-query " \fIvariable-name\fP"
+Print the value of a single variable.
+.TP
+.BR \-s ", " \-\-print\-set
+Print an export command. This can be used to set the environment variables
+using eval.
+.TP
+.BR \-u ", " \-\-print\-unset
+Print a similar command to \fB\-\-print\-unset\fP but to unset all variables.
+.TP
+.BR \-c ", " \-\-command " \fIcommand-string\fP"
+Execute a \fIcommand-string\fP in an environment which has all variables
+set to the determined value.
+.TP
+.BR \-L ", " \-\-list\-known
+Print a list of valid architecture names.
+Possibly restricted by one or more of the matching options
+\fB\-\-match\-wildcard\fP, \fB\-\-match\-bits\fP or \fB\-\-match\-endian\fP
+(since dpkg 1.17.14).
+.TP
+.BR \-? ", " \-\-help
+Show the usage message and exit.
+.TP
+.B \-\-version
+Show the version and exit.
+.
+.SH OPTIONS
+.TP
+.BR \-a ", " \-\-host\-arch " \fIarchitecture\fP"
+Set the host Debian architecture.
+.TP
+.BR \-t ", " \-\-host\-type " \fIgnu-system-type\fP"
+Set the host GNU system type.
+.TP
+.BR \-A ", " \-\-target\-arch " \fIarchitecture\fP"
+Set the target Debian architecture (since dpkg 1.17.14).
+.TP
+.BR \-T ", " \-\-target\-type " \fIgnu-system-type\fP"
+Set the target GNU system type (since dpkg 1.17.14).
+.TP
+.BR \-W ", " \-\-match\-wildcard " \fIarchitecture-wildcard\fP"
+Restrict the architectures listed by \fB\-\-list\-known\fP to ones matching
+the specified architecture wildcard (since dpkg 1.17.14).
+.TP
+.BR \-B ", " \-\-match\-bits " \fIarchitecture-bits\fP"
+Restrict the architectures listed by \fB\-\-list\-known\fP to ones with the
+specified CPU bits (since dpkg 1.17.14). Either \fB32\fP or \fB64\fP.
+.TP
+.BR \-E ", " \-\-match\-endian " \fIarchitecture-endianness\fP"
+Restrict the architectures listed by \fB\-\-list\-known\fP to ones with the
+specified endianness (since dpkg 1.17.14). Either \fBlittle\fP or \fBbig\fP.
+.TP
+.BR \-f ", " \-\-force
+Values set by existing environment variables with the same name as used by
+the scripts are honored (i.e. used by \fBdpkg\-architecture\fP), except if
+this force flag is present. This allows the user
+to override a value even when the call to \fBdpkg\-architecture\fP is buried
+in some other script (for example \fBdpkg\-buildpackage\fP(1)).
+.
+.SH TERMS
+.IP "build machine" 4
+The machine the package is built on.
+.IP "host machine" 4
+The machine the package is built for.
+.IP "target machine" 4
+The machine the compiler is building for.
+This is only needed when building a cross-toolchain, one that will be built
+on the build architecture, to be run on the host architecture, and to build
+code for the target architecture.
+.IP "Debian architecture" 4
+The Debian architecture string, which specifies the binary tree in the
+FTP archive. Examples: i386, sparc, hurd\-i386.
+.IP "Debian architecture tuple" 4
+A Debian architecture tuple is the fully qualified architecture with all its
+components spelled out.
+This differs with Debian architectures in that at least the \fIcpu\fP
+component does not embed the \fIabi\fP.
+The current tuple has the form \fIabi\fP\-\fIlibc\fP\-\fIos\fP\-\fIcpu\fP.
+Examples: base\-gnu\-linux\-amd64, eabihf\-musl\-linux\-arm.
+.IP "Debian architecture wildcard" 4
+A Debian architecture wildcard is a special architecture string that will
+match any real architecture being part of it.
+The general form is a Debian architecture tuple with four or less elements,
+and with at least one of them being \fBany\fP.
+Missing elements of the tuple are prefixed implicitly as \fBany\fP, and thus
+the following pairs are equivalent:
+.nf
+    \fBany\fP\-\fBany\fP\-\fBany\fP\-\fBany\fP = \fBany\fP
+    \fBany\fP\-\fBany\fP\-\fIos\fP\-\fBany\fP = \fIos\fP\-\fBany\fP
+    \fBany\fP\-\fIlibc\fP\-\fBany\fP\-\fBany\fP = \fIlibc\fP\-\fBany\fP\-\fBany\fP
+.fi
+Examples: linux\-any, any\-i386, hurd\-any, eabi\-any\-any\-arm,
+musl\-any\-any.
+.IP "GNU system type" 4
+An architecture specification string consisting of two parts separated by
+a hyphen: cpu and system.
+Examples: i586\-linux\-gnu, sparc\-linux\-gnu, i686\-gnu, x86_64\-netbsd.
+.IP "multiarch triplet" 4
+The clarified GNU system type, used for filesystem paths.
+This triplet does not change even when the baseline ISA gets bumped,
+so that the resulting paths are stable over time.
+The only current difference with the GNU system type is that the CPU part
+for i386 based systems is always i386.
+Examples: i386\-linux\-gnu, x86_64\-linux\-gnu.
+Example paths: /lib/powerpc64le-linux-gnu/, /usr/lib/i386-kfreebsd-gnu/.

+.SH FILES
+.SS Architecture tables
+All these files have to be present for \fBdpkg\-architecture\fP to
+work. Their location can be overridden at runtime with the environment
+variable \fBDPKG_DATADIR\fP.
+These tables contain a format \fBVersion\fP pseudo-field on their first
+line to mark their format, so that parsers can check if they understand
+it, such as "# Version=1.0".
+.TP
+.I %PKGDATADIR%/cputable
+Table of known CPU names and mapping to their GNU name.
+Format version 1.0 (since dpkg 1.13.2).
+.TP
+.I %PKGDATADIR%/ostable
+Table of known operating system names and mapping to their GNU name.
+Format version 2.0 (since dpkg 1.18.11).
+.TP
+.I %PKGDATADIR%/tupletable
+Mapping between Debian architecture tuples and Debian architecture
+names.
+Format version 1.0 (since dpkg 1.18.11).
+.TP
+.I %PKGDATADIR%/abitable
+Table of Debian architecture ABI attribute overrides.
+Format version 2.0 (since dpkg 1.18.11).
+.SS Packaging support
+.TP
+.I %PKGDATADIR%/architecture.mk
+Makefile snippet that properly sets and exports all the variables that
+\fBdpkg\-architecture\fP outputs (since dpkg 1.16.1).
+.
+.SH EXAMPLES
+\fBdpkg\-buildpackage\fP accepts the \fB\-a\fR option and passes it to
+\fBdpkg\-architecture\fP. Other examples:
+.IP
+CC=i386\-gnu\-gcc dpkg\-architecture \-c debian/rules build
+.IP
+eval \`dpkg\-architecture \-u\`
+.PP
+Check if the current or specified host architecture is equal to an
+architecture:
+.IP
+dpkg\-architecture \-elinux\-alpha
+.IP
+dpkg\-architecture \-amips \-elinux\-mips
+.PP
+Check if the current or specified host architecture is a Linux system:
+.IP
+dpkg\-architecture \-ilinux\-any
+.IP
+dpkg\-architecture \-ai386 \-ilinux\-any
+.
+.SS Usage in debian/rules
+The environment variables set by \fBdpkg\-architecture\fP are passed to
+\fIdebian/rules\fP as make variables (see make documentation). However,
+you should not rely on them, as this breaks manual invocation of the
+script. Instead, you should always initialize them using
+\fBdpkg\-architecture\fP with the \fB\-q\fP option. Here are some examples,
+which also show how you can improve the cross compilation support in your
+package:
+.PP
+Retrieving the GNU system type and forwarding it to ./configure:
+.PP
+.RS 4
+.nf
+DEB_BUILD_GNU_TYPE ?= $(shell dpkg\-architecture \-qDEB_BUILD_GNU_TYPE)
+DEB_HOST_GNU_TYPE ?= $(shell dpkg\-architecture \-qDEB_HOST_GNU_TYPE)
+[...]
+ifeq ($(DEB_BUILD_GNU_TYPE), $(DEB_HOST_GNU_TYPE))
+  confflags += \-\-build=$(DEB_HOST_GNU_TYPE)
+else
+  confflags += \-\-build=$(DEB_BUILD_GNU_TYPE) \\
+               \-\-host=$(DEB_HOST_GNU_TYPE)
+endif
+[...]
+\&./configure $(confflags)
+.fi
+.RE
+.PP
+Doing something only for a specific architecture:
+.PP
+.RS 4
+.nf
+DEB_HOST_ARCH ?= $(shell dpkg\-architecture \-qDEB_HOST_ARCH)
+
+ifeq ($(DEB_HOST_ARCH),alpha)
+  [...]
+endif
+.fi
+.RE
+.PP
+or if you only need to check the CPU or OS type, use the
+\fBDEB_HOST_ARCH_CPU\fP or \fBDEB_HOST_ARCH_OS\fP variables.
+.PP
+Note that you can also rely on an external Makefile snippet to properly
+set all the variables that \fBdpkg\-architecture\fP can provide:
+.PP
+.RS 4
+.nf
+include %PKGDATADIR%/architecture.mk
+
+ifeq ($(DEB_HOST_ARCH),alpha)
+  [...]
+endif
+.fi
+.RE
+.PP
+In any case, you should never use \fBdpkg \-\-print\-architecture\fP to get
+architecture information during a package build.
+.
+.SH ENVIRONMENT
+.TP
+.B DPKG_DATADIR
+If set, it will be used as the \fBdpkg\fP data directory, where the
+architecture tables are located (since dpkg 1.14.17).
+Defaults to «%PKGDATADIR%».
