106# This function is for bulk patching, or in theory for just one
107# or two patches.
108#
109# It should work with .bz2, .gz, .zip and plain text patches.
110# Currently all patches should be the same format.
111#
112# You do not have to specify '-p' option to patch, as it will
113# try with -p0 to -p5 until it succeed, or fail at -p5.
114#
115# Above EPATCH_* variables can be used to control various defaults,
116# bug they should be left as is to ensure an ebuild can rely on
117# them for.
118#
119# Patches are applied in current directory.
120#
121# Bulk Patches should preferibly have the form of:
122#
123# ??_${ARCH}_foo.${EPATCH_SUFFIX}
124#
125# For example:
126#
127# 01_all_misc-fix.patch.bz2
128# 02_sparc_another-fix.patch.bz2

130# This ensures that there are a set order, and you can have ARCH
131# specific patches.

134# single patch that need to be applied if its a file. If on the other
135# hand its a directory, it will set EPATCH_SOURCE to this.

797# sometimes the function call is _llseek or something) and steal the 2nd

799# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek

801# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
