		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!

		153	# Since changing shell options can easily break other pieces of code (which
		154	# assume the default state), eshopts_push is used to (1) push the current shell
		155	# options onto a stack and (2) pass the specified arguments to set.

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

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

107	# This function is for bulk patching, or in theory for just one	265	# @FUNCTION: epatch
108	# or two patches.	266	# @USAGE: [options] [patches] [dirs of patches]
		267	# @DESCRIPTION:
		268	# epatch is designed to greatly simplify the application of patches. It can
		269	# process patch files directly, or directories of patches. The patches may be
		270	# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
		271	# the -p option as epatch will automatically attempt -p0 to -p5 until things
		272	# apply successfully.
109	#	273	#
110	# It should work with .bz2, .gz, .zip and plain text patches.	274	# If you do not specify any patches/dirs, then epatch will default to the
111	# Currently all patches should be the same format.	275	# directory specified by EPATCH_SOURCE.
112	#	276	#
113	# You do not have to specify '-p' option to patch, as it will	277	# Any options specified that start with a dash will be passed down to patch
114	# try with -p0 to -p5 until it succeed, or fail at -p5.	278	# for this specific invocation. As soon as an arg w/out a dash is found, then
		279	# arg processing stops.
115	#	280	#
116	# Above EPATCH_* variables can be used to control various defaults,	281	# When processing directories, epatch will apply all patches that match:
117	# bug they should be left as is to ensure an ebuild can rely on	282	# @CODE
118	# them for.	283	# if ${EPATCH_FORCE} != "yes"
119	#
120	# Patches are applied in current directory.
121	#
122	# Bulk Patches should preferibly have the form of:
123	#
124	# ??_${ARCH}_foo.${EPATCH_SUFFIX}	284	# ??_${ARCH}_foo.${EPATCH_SUFFIX}
		285	# else
		286	# *.${EPATCH_SUFFIX}
		287	# @CODE
		288	# The leading ?? are typically numbers used to force consistent patch ordering.
		289	# The arch field is used to apply patches only for the host architecture with
		290	# the special value of "all" means apply for everyone. Note that using values
		291	# other than "all" is highly discouraged -- you should apply patches all the
		292	# time and let architecture details be detected at configure/compile time.
125	#	293	#
126	# For example:	294	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		295	# for patches to apply.
127	#	296	#
128	# 01_all_misc-fix.patch.bz2	297	# Refer to the other EPATCH_xxx variables for more customization of behavior.
129	# 02_sparc_another-fix.patch.bz2
130	#
131	# This ensures that there are a set order, and you can have ARCH
132	# specific patches.
133	#
134	# If you however give an argument to epatch(), it will treat it as a
135	# single patch that need to be applied if its a file. If on the other
136	# hand its a directory, it will set EPATCH_SOURCE to this.
