105# This function is for bulk patching, or in theory for just one
106# or two patches.
107#
108# It should work with .bz2, .gz, .zip and plain text patches.
109# Currently all patches should be the same format.
110#
111# You do not have to specify '-p' option to patch, as it will
112# try with -p0 to -p5 until it succeed, or fail at -p5.
113#
114# Above EPATCH_* variables can be used to control various defaults,
115# bug they should be left as is to ensure an ebuild can rely on
116# them for.
117#
118# Patches are applied in current directory.
119#
120# Bulk Patches should preferibly have the form of:
121#
122# ??_${ARCH}_foo.${EPATCH_SUFFIX}
123#
124# For example:
125#
126# 01_all_misc-fix.patch.bz2
127# 02_sparc_another-fix.patch.bz2
128#
129# This ensures that there are a set order, and you can have ARCH
130# specific patches.
131#
132# If you however give an argument to epatch(), it will treat it as a
133# single patch that need to be applied if its a file. If on the other
134# hand its a directory, it will set EPATCH_SOURCE to this.
