762# new convenience patch wrapper function to eventually replace epatch(),
763# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
764# /usr/bin/patch
765# Features:
766# - bulk patch handling similar to epatch()'s
767# - automatic patch level detection like epatch()'s
768# - automatic patch uncompression like epatch()'s
769# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
770# manually instead
771# - once I decide it's production-ready, it'll be called from base_src_unpack
772# to handle $PATCHES to avoid defining src_unpack just to use xpatch
773
774# accepts zero or more parameters specifying patchfiles and/or patchdirs
775
776# known issues:
777# - only supports unified style patches (does anyone _really_ use anything
778# else?)
779# - because it doesn't use --dry-run there is a risk of it failing
780# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
781# any of the backup heuristics that patch employs to discover a filename.
782# however, this isn't dangerous because if it works for the developer who's
783# writing the ebuild, it'll always work for the users, and if it doesn't,
784# then we'll fix it :-)
785# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).
