762# Features:
763# - bulk patch handling similar to epatch()'s
764# - automatic patch level detection like epatch()'s
765# - automatic patch uncompression like epatch()'s
766# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
767# manually instead
768# - once I decide it's production-ready, it'll be called from base_src_unpack
769# to handle $PATCHES to avoid defining src_unpack just to use xpatch
770
771# accepts zero or more parameters specifying patchfiles and/or patchdirs

773# known issues:
774# - only supports unified style patches (does anyone _really_ use anything

776# - because it doesn't use --dry-run there is a risk of it failing
777# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
778# any of the backup heuristics that patch employs to discover a filename.
779# however, this isn't dangerous because if it works for the developer who's
780# writing the ebuild, it'll always work for the users, and if it doesn't,
781# then we'll fix it :-)

939# Unpack those pesky pdv generated files ...

943#
944# Usage: unpack_pdv [file to unpack] [size of off_t]
945# - you have to specify the off_t size ... i have no idea how to extract that
946# information out of the binary executable myself. basically you pass in
947# the size of the off_t type (in bytes) on the machine that built the pdv
948# archive. one way to determine this is by running the following commands:
949# strings <pdv archive> | grep lseek
950# strace -elseek <pdv archive>
951# basically look for the first lseek command (we do the strings/grep because
952# sometimes the function call is _llseek or something) and steal the 2nd
953# parameter. here is an example:
954# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
955# lseek
956# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
957# lseek(3, -4, SEEK_END) = 2981250
958# thus we would pass in the value of '4' as the second parameter.

1163# found at CDROM_ROOT.
