# $NetBSD: bsd.pkg.patch.mk,v 1.3 2005/05/14 22:31:04 jlam Exp $
#
# This Makefile fragment is included by bsd.pkg.mk and defines the
# relevant variables and targets for the "patch" phase.
#
# The following variables may be set in a package Makefile and control
# how pkgsrc patches are applied.
#
# PATCH_STRIP is a patch(1) argument that sets the pathname strip
# count to help find the correct files to patch. See the patch(1)
# man page for more details. Defaults to "-p0".
#
# PATCH_ARGS is the base set of arguments passed to patch(1).
# The default set of arguments will apply the patches to the
# files in ${WRKSRC} with any ${PATCH_STRIP} arguments set.
#
# The following variables may be set in a package Makefile and control
# how "distribution" patches are applied.
#
# PATCHFILES is a list of distribution patches relative to
# ${_DISTDIR} that are applied first to the package.
#
# PATCH_DIST_STRIP is a patch(1) argument that sets the pathname
# strip count to help find the correct files to patch. See the
# patch(1) man page for more details. Defaults to "-p0".
#
# PATCH_DIST_ARGS is the base set of arguments passed to patch(1).
# The default set of arguments will apply the patches to the
# files in ${WRKSRC} with any ${PATCH_DIST_STRIP} arguments set.
#
# PATCH_DIST_CAT is the command that outputs the contents of the
# "$patchfile" to stdout. The default value is a command that
# can output gzipped, bzipped, or plain patches to stdout.
#
# PATCH_DIST_STRIP.<patchfile>
# PATCH_DIST_ARGS.<patchfile>
# PATCH_DIST_CAT.<patchfile>
# These are versions of the previous three variables which allow
# for customization of their values for specific patchfiles.
#
# The following variables may be set by the user and affect how patching
# occurs:
#
# PATCH_DEBUG, if defined, causes the the patch process to be more
# verbose.
#
# PATCH_FUZZ_FACTOR is a patch(1) argument that specifies how much
# fuzz to accept when applying pkgsrc patches. See the patch(1)
# man page for more details. Defaults to "-F0" for zero fuzz.
#
# LOCALPATCHES is the location of local patches that are maintained
# in a directory tree reflecting the same hierarchy as the pkgsrc
# tree, e.g., local patches for www/apache would be found in
# ${LOCALPATCHES}/www/apache. These patches are applied after
# the patches in ${PATCHDIR}.
#
# The following targets are defined by bsd.pkg.patch.mk:
#
# do-patch is the target that causes the actual patching of the
# extracted sources to occur during the "patch" phase.
