dh_quilt_unpatch - unapply patches listed in debian/patches/series
dh_quilt_unpatch [debhelper options]
dh_quilt_unpatch simply calls quilt pop -a after having set the environment variable QUILT_PATCHES to debian/patches. All patches listed in debian/patches/series are then unapplied in the current directory. The command does not fail if the patches have already been unapplied.
You can use another directory instead of debian/patches by setting (and exporting) the environment variable QUILT_PATCH_DIR.
dh_quilt_unpatch is usually called indirectly in a rules file via the dh command.
%: dh $@ --with quilt
It can also be direcly called in the clean rule.
clean: dh_testdir dh_testroot [ ! -f Makefile ] || $(MAKE) clean dh_quilt_unpatch dh_clean
This tool is useless if you use the source package format 3.0 (quilt). Consider switching to this source format if you haven't done it yet.
This program is meant to be used together with debhelper.
