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!

1133# the middle of the archive. Valve seems to use it a lot ... too bad
1134# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1135#
1136# You have to specify the off_t size ... I have no idea how to extract that
1137# information out of the binary executable myself. Basically you pass in
1138# the size of the off_t type (in bytes) on the machine that built the pdv
1139# archive.
1140#
1141# One way to determine this is by running the following commands:

1143# @CODE
1144# strings <pdv archive> | grep lseek
1145# strace -elseek <pdv archive>
1146# @CODE
1147#
1148# Basically look for the first lseek command (we do the strings/grep because
1149# sometimes the function call is _llseek or something) and steal the 2nd
1150# parameter. Here is an example:
1151#
1152# @CODE
1153# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1154# lseek
1155# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1156# lseek(3, -4, SEEK_END) = 2981250
1157# @CODE
1158#
1159# Thus we would pass in the value of '4' as the second parameter.

1718# not actually support the defined USE flags (aka listed in IUSE).

1720# the requirements of the USE flags. They correspond to "and" and "or"

1723# enabled. The --hidden option is really for internal use only as it
1724# means the USE flag we're checking is hidden expanded, so it won't be found
1725# in IUSE like normal USE flags.
