966# @DESCRIPTION:
967# Unpack those pesky pdv generated files ...
968# They're self-unpacking programs with the binary package stuffed in
969# the middle of the archive. Valve seems to use it a lot ... too bad
970# it seems to like to segfault a lot :(. So lets take it apart ourselves.
971#
972# You have to specify the off_t size ... I have no idea how to extract that
973# information out of the binary executable myself. Basically you pass in
974# the size of the off_t type (in bytes) on the machine that built the pdv
975# archive.
976#
977# One way to determine this is by running the following commands:
978#
979# @CODE
980# strings <pdv archive> | grep lseek
981# strace -elseek <pdv archive>
982# @CODE
983#
984# Basically look for the first lseek command (we do the strings/grep because
985# sometimes the function call is _llseek or something) and steal the 2nd
986# parameter. Here is an example:
987#
988# @CODE
989# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
990# lseek
991# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
992# lseek(3, -4, SEEK_END) = 2981250
993# @CODE
994#
995# Thus we would pass in the value of '4' as the second parameter.
