NAME

       dpkg-buildtree - helper for build tree operations during package builds

SYNOPSIS

       dpkg-buildtree [option...] [command]

DESCRIPTION

       dpkg-buildtree is a tool to perform common operations on the build tree for a source
       package.

       This program was introduced in dpkg 1.22.3.

COMMANDS

       clean
           Removes all artifacts generated during a build by the various dpkg tools, and
           pathnames used or controlled by dpkg tools that are safe to clean.  These files are
           used to track state between package build runs, and are in many cases internal
           implementation details the packager should not be concerned about, or are staging
           directories containing build artifacts.

       --help
           Show the usage message and exit.

       --version
           Show the version and exit.

FILES

   Cleaned files
       debian/files
       debian/files.new
           Files generated by dpkg-distaddfile(1).

       debian/substvars
       debian/substvars.new
           Files generated by dpkg-shlibdeps(1).

       debian/tmp
           Staging directory containing the contents to be used when creating a package.  Both
           dpkg-gencontrol(1) and dpkg-gensymbols(1) generate files within.

EXAMPLES

   Usage in debian/rules
       You can call dpkg-buildtree clean from the debian/rules clean target, after having
       performed other necessary cleanups.

       For example for an autoconf-like build system:

         clean:
               [ ! -f Makefile ] || $(MAKE) distclean
               dpkg-buildtree clean
