		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!

106	# To use, simply call:	106	# If the first argument is '-s' or '-u', we assume you want to call `shopt`

182	# This function is for bulk patching, or in theory for just one	191	# @FUNCTION: epatch
183	# or two patches.	192	# @USAGE: [patches] [dirs of patches]
		193	# @DESCRIPTION:
		194	# epatch is designed to greatly simplify the application of patches. It can
		195	# process patch files directly, or directories of patches. The patches may be
		196	# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
		197	# the -p option as epatch will automatically attempt -p0 to -p5 until things
		198	# apply successfully.
184	#	199	#
185	# It should work with .bz2, .gz, .zip and plain text patches.	200	# If you do not specify any options, then epatch will default to the directory
186	# Currently all patches should be the same format.	201	# specified by EPATCH_SOURCE.
187	#	202	#
188	# You do not have to specify '-p' option to patch, as it will	203	# When processing directories, epatch will apply all patches that match:
189	# try with -p0 to -p5 until it succeed, or fail at -p5.	204	# @CODE
190	#	205	# ${EPATCH_FORCE} == "yes"
191	# Above EPATCH_* variables can be used to control various defaults,
192	# bug they should be left as is to ensure an ebuild can rely on
193	# them for.
194	#
195	# Patches are applied in current directory.
196	#
197	# Bulk Patches should preferibly have the form of:
198	#
199	# ??_${ARCH}_foo.${EPATCH_SUFFIX}	206	# ??_${ARCH}_foo.${EPATCH_SUFFIX}
		207	# else
		208	# *.${EPATCH_SUFFIX}
		209	# @CODE
		210	# The leading ?? are typically numbers used to force consistent patch ordering.
		211	# The arch field is used to apply patches only for the host architecture with
		212	# the special value of "all" means apply for everyone. Note that using values
		213	# other than "all" is highly discouraged -- you should apply patches all the
		214	# time and let architecture details be detected at configure/compile time.
200	#	215	#
201	# For example:	216	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		217	# for patches to apply.
202	#	218	#
203	# 01_all_misc-fix.patch.bz2	219	# Refer to the other EPATCH_xxx variables for more customization of behavior.
204	# 02_sparc_another-fix.patch.bz2
205	#
206	# This ensures that there are a set order, and you can have ARCH
207	# specific patches.
208	#
209	# If you however give an argument to epatch(), it will treat it as a
210	# single patch that need to be applied if its a file. If on the other
211	# hand its a directory, it will set EPATCH_SOURCE to this.
