643# new convinience patch wapper function to eventually replace epatch(), $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and /usr/bin/patch
644# Features:
645# - bulk patch handling similar to epatch()'s
646# - automatic patch level detection like epatch()'s
647# - semiautomatic patch uncompression like epatch()'s (may switch to using /usr/bin/file for extra power, instead of just looking at the filename)
648# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles manually instead
649# - is called from base_src_unpack to handle $PATCHES to avoid defining src_unpack(-) just to use xpatch
650
651# accepts zero or more parameters specifying patchfiles and/or patchdirs
652
653# known issues:
654# - only supports unified style patches (does anyone _really_ use anything else?)
655# - first file addressed in a patch can't have spaces in its name or in the path mentioned in the patchfile
656# (can be easily fixed to be: at least one file addressed in the patch must have no spaces...)
