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!

83# Above EPATCH_* variables can be used to control various defaults,

97#
98# This ensures that there are a set order, and you can have ARCH
99# specific patches.

102# single patch that need to be applied if its a file. If on the other

1083# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1084# lseek(3, -4, SEEK_END) = 2981250
