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
