646# Features:
647# - bulk patch handling similar to epatch()'s
648# - automatic patch level detection like epatch()'s
649# - automatic patch uncompression like epatch()'s
650# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
651# manually instead
652# - once I decide it's production-ready, it'll be called from base_src_unpack
653# to handle $PATCHES to avoid defining src_unpack just to use xpatch
654 712

660# - because it doesn't use --dry-run there is a risk of it failing 722#
661# to find the files to patch, ie detect the patchlevel, properly. It doesn't use 723# make_desktop_entry(<binary>, [name], [icon], [type], [path])
662# any of the backup heuristics that patch employs to discover a filename. 724#
663# however, this isn't dangerous because if it works for the developer who's 725# binary: what binary does the app run with ?

959# Usage: unpack_pdv [file to unpack] [size of off_t]
960# - you have to specify the off_t size ... i have no idea how to extract that

962# the size of the off_t type (in bytes) on the machine that built the pdv
963# archive. one way to determine this is by running the following commands:
964# strings <pdv archive> | grep lseek
965# strace -elseek <pdv archive>
966# basically look for the first lseek command (we do the strings/grep because
967# sometimes the function call is _llseek or something) and steal the 2nd
968# parameter. here is an example:
969# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
970# lseek
971# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
