		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!

		155	# Since changing shell options can easily break other pieces of code (which

		160	# rather than `set` as there are some options only available via that.

		163	# may be used with variables/arguments to custom functions. That would be:

105	# This function is for bulk patching, or in theory for just one	267	# @FUNCTION: epatch
106	# or two patches.	268	# @USAGE: [options] [patches] [dirs of patches]
		269	# @DESCRIPTION:
		270	# epatch is designed to greatly simplify the application of patches. It can
		271	# process patch files directly, or directories of patches. The patches may be
		272	# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
		273	# the -p option as epatch will automatically attempt -p0 to -p5 until things
		274	# apply successfully.
107	#	275	#
108	# It should work with .bz2, .gz, .zip and plain text patches.	276	# If you do not specify any patches/dirs, then epatch will default to the
109	# Currently all patches should be the same format.	277	# directory specified by EPATCH_SOURCE.
110	#	278	#
111	# You do not have to specify '-p' option to patch, as it will	279	# Any options specified that start with a dash will be passed down to patch
112	# try with -p0 to -p5 until it succeed, or fail at -p5.	280	# for this specific invocation. As soon as an arg w/out a dash is found, then
		281	# arg processing stops.
113	#	282	#
114	# Above EPATCH_* variables can be used to control various defaults,	283	# When processing directories, epatch will apply all patches that match:
115	# bug they should be left as is to ensure an ebuild can rely on	284	# @CODE
116	# them for.	285	# if ${EPATCH_FORCE} != "yes"
117	#
118	# Patches are applied in current directory.
119	#
120	# Bulk Patches should preferibly have the form of:
121	#
122	# ??_${ARCH}_foo.${EPATCH_SUFFIX}	286	# ??_${ARCH}_foo.${EPATCH_SUFFIX}
		287	# else
		288	# *.${EPATCH_SUFFIX}
		289	# @CODE
		290	# The leading ?? are typically numbers used to force consistent patch ordering.
		291	# The arch field is used to apply patches only for the host architecture with
		292	# the special value of "all" means apply for everyone. Note that using values
		293	# other than "all" is highly discouraged -- you should apply patches all the
		294	# time and let architecture details be detected at configure/compile time.
123	#	295	#
124	# For example:	296	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		297	# for patches to apply.
125	#	298	#
126	# 01_all_misc-fix.patch.bz2	299	# Refer to the other EPATCH_xxx variables for more customization of behavior.
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.
