8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

1110# They're self-unpacking programs with the binary package stuffed in
1111# the middle of the archive. Valve seems to use it a lot ... too bad
1112# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1113#
1114# You have to specify the off_t size ... I have no idea how to extract that
1115# information out of the binary executable myself. Basically you pass in
1116# the size of the off_t type (in bytes) on the machine that built the pdv
1117# archive.
1118#
1119# One way to determine this is by running the following commands:
1120#
1121# @CODE
1122# strings <pdv archive> | grep lseek
1123# strace -elseek <pdv archive>
1124# @CODE
1125#
1126# Basically look for the first lseek command (we do the strings/grep because
1127# sometimes the function call is _llseek or something) and steal the 2nd
1128# parameter. Here is an example:
1129#
1130# @CODE
1131# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1132# lseek
1133# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1134# lseek(3, -4, SEEK_END) = 2981250
1135# @CODE
1136#
1137# Thus we would pass in the value of '4' as the second parameter.

1700# while the -o flag means at least one of the listed IUSE flags must be
1701# enabled. The --hidden option is really for internal use only as it
1702# means the USE flag we're checking is hidden expanded, so it won't be found
