		155	# Since changing shell options can easily break other pieces of code (which
		156	# assume the default state), eshopts_push is used to (1) push the current shell
		157	# options onto a stack and (2) pass the specified arguments to set.
		158	#
		159	# If the first argument is '-s' or '-u', we assume you want to call `shopt`
		160	# rather than `set` as there are some options only available via that.
		161	#
		162	# A common example is to disable shell globbing so that special meaning/care
		163	# may be used with variables/arguments to custom functions. That would be:

74	# This function is for bulk patching, or in theory for just one	267	# @FUNCTION: epatch
75	# 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.
76	#	275	#
77	# 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
78	# Currently all patches should be the same format.	277	# directory specified by EPATCH_SOURCE.
79	#	278	#
80	# 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
81	# 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.
82	#	282	#
83	# Above EPATCH_* variables can be used to control various defaults,	283	# When processing directories, epatch will apply all patches that match:
84	# bug they should be left as is to ensure an ebuild can rely on	284	# @CODE
85	# them for.	285	# if ${EPATCH_FORCE} != "yes"
86	#
87	# Patches are applied in current directory.
88	#
89	# Bulk Patches should preferibly have the form of:
90	#
91	# ??_${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.
92	#	295	#
93	# For example:	296	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		297	# for patches to apply.
94	#	298	#
95	# 01_all_misc-fix.patch.bz2	299	# Refer to the other EPATCH_xxx variables for more customization of behavior.
96	# 02_sparc_another-fix.patch.bz2
97	#
98	# This ensures that there are a set order, and you can have ARCH
99	# specific patches.
100	#
101	# If you however give an argument to epatch(), it will treat it as a
102	# single patch that need to be applied if its a file. If on the other
103	# hand its a directory, it will set EPATCH_SOURCE to this.

		563	# desire. Obviously, there can be no official support for arbitrarily

		1381	# @USAGE: [--all]
		1382	# @DESCRIPTION:
		1383	# Locate unnecessary libtool files (.la) and libtool static archives
		1384	# (.a) and remove them from installation image.
		1385	#
		1386	# By default, .la files are removed whenever the static linkage can
		1387	# either be performed using pkg-config or doesn't introduce additional
		1388	# flags.
		1389	#
		1390	# If '--all' argument is passed, all .la files are removed. This is
		1391	# usually useful when the package installs plugins and does not use .la
		1392	# files for loading them.
		1393	#
		1394	# The .a files are only removed whenever corresponding .la files state
		1395	# that they should not be linked to, i.e. whenever these files
		1396	# correspond to plugins.
		1397	#
		1398	# Note: if your package installs any .pc files, this function implicitly
		1399	# calls pkg-config. You should add it to your DEPEND in that case.
