		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.

		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:

95	# This function is for bulk patching, or in theory for just one	267	# @FUNCTION: epatch
96	# 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.
97	#	275	#
98	# 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
99	# Currently all patches should be the same format.	277	# directory specified by EPATCH_SOURCE.
100	#	278	#
101	# 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
102	# 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.
103	#	282	#
104	# Above EPATCH_* variables can be used to control various defaults,	283	# When processing directories, epatch will apply all patches that match:
105	# bug they should be left as is to ensure an ebuild can rely on	284	# @CODE
106	# them for.	285	# if ${EPATCH_FORCE} != "yes"
107	#
108	# Patches are applied in current directory.
109	#
110	# Bulk Patches should preferably have the form of:
111	#
112	# ??_${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.
113	#	295	#
114	# For example:	296	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		297	# for patches to apply.
115	#	298	#
116	# 01_all_misc-fix.patch.bz2	299	# Refer to the other EPATCH_xxx variables for more customization of behavior.
117	# 02_sparc_another-fix.patch.bz2
118	#
119	# This ensures that there are a set order, and you can have ARCH
120	# specific patches.
121	#
122	# If you however give an argument to epatch(), it will treat it as a
123	# single patch that need to be applied if its a file. If on the other
124	# hand its a directory, it will set EPATCH_SOURCE to this.

		562	# modifications, as well as for permanent customizations a user might
		563	# desire. Obviously, there can be no official support for arbitrarily
		564	# patched ebuilds. So whenever a build log in a bug report mentions that
		565	# user patches were applied, the user should be asked to reproduce the
		566	# problem without these.

		568	# Not all ebuilds do call this function, so placing patches in the
		569	# stated directory might or might not work, depending on the package and
		570	# the eclasses it inherits and uses. It is safe to call the function
		571	# repeatedly, so it is always possible to add a call at the ebuild
		572	# level. The first call is the time when the patches will be
		573	# applied.

		576	# have been applied, so that their code can be modified as well, but
