		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.
4	#	14	#
5	# This eclass is for general purpose functions that most ebuilds	15	# Due to the nature of this eclass, some functions may have maintainers
6	# have to implement themselves.	16	# different from the overall eclass!

111	# This function is for bulk patching, or in theory for just one	170	# @FUNCTION: epatch
112	# or two patches.	171	# @USAGE: [patches] [dirs of patches]
		172	# @DESCRIPTION:
		173	# epatch is designed to greatly simplify the application of patches. It can
		174	# process patch files directly, or directories of patches. The patches may be
		175	# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
		176	# the -p option as epatch will automatically attempt -p0 to -p5 until things
		177	# apply successfully.
113	#	178	#
114	# It should work with .bz2, .gz, .zip and plain text patches.	179	# If you do not specify any options, then epatch will default to the directory
115	# Currently all patches should be the same format.	180	# specified by EPATCH_SOURCE.
116	#	181	#
117	# You do not have to specify '-p' option to patch, as it will	182	# When processing directories, epatch will apply all patches that match:
118	# try with -p0 to -p5 until it succeed, or fail at -p5.	183	# @CODE
119	#	184	# ${EPATCH_FORCE} == "yes"
120	# Above EPATCH_* variables can be used to control various defaults,
121	# bug they should be left as is to ensure an ebuild can rely on
122	# them for.
123	#
124	# Patches are applied in current directory.
125	#
126	# Bulk Patches should preferibly have the form of:
127	#
128	# ??_${ARCH}_foo.${EPATCH_SUFFIX}	185	# ??_${ARCH}_foo.${EPATCH_SUFFIX}
		186	# else
		187	# *.${EPATCH_SUFFIX}
		188	# @CODE
		189	# The leading ?? are typically numbers used to force consistent patch ordering.
		190	# The arch field is used to apply patches only for the host architecture with
		191	# the special value of "all" means apply for everyone. Note that using values
		192	# other than "all" is highly discouraged -- you should apply patches all the
		193	# time and let architecture details be detected at configure/compile time.
129	#	194	#
130	# For example:	195	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		196	# for patches to apply.
131	#	197	#
132	# 01_all_misc-fix.patch.bz2	198	# Refer to the other EPATCH_xxx variables for more customization of behavior.
133	# 02_sparc_another-fix.patch.bz2
134	#
135	# This ensures that there are a set order, and you can have ARCH
136	# specific patches.
137	#
138	# If you however give an argument to epatch(), it will treat it as a
139	# single patch that need to be applied if its a file. If on the other
140	# hand its a directory, it will set EPATCH_SOURCE to this.
