       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

           Sets the color mode.  The currently accepted values are: auto (default), always and never.

       DPKG_NLS
           If  set,  it  will  be  used  to  decide  whether  to activate Native Language Support, also known as
           internationalization (or i18n) support.  The accepted values are: 0 and 1 (default).

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
