		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!

20	# in some cases when linking dynamic, the .a in /usr/lib is used
21	# instead of the .so in /lib due to gcc/libtool tweaking ld's

		100	# @USAGE: [options to `set` or `shopt`]
		101	# @DESCRIPTION:
		102	# Often times code will want to enable a shell option to change code behavior.
		103	# Since changing shell options can easily break other pieces of code (which
		104	# assume the default state), eshopts_push is used to (1) push the current shell
		105	# options onto a stack and (2) pass the specified arguments to set.
		106	#
		107	# If the first argument is '-s' or '-u', we assume you want to call `shopt`
		108	# rather than `set` as there are some options only available via that.
		109	#
		110	# A common example is to disable shell globbing so that special meaning/care
		111	# may be used with variables/arguments to custom functions. That would be:
		112	# @CODE
		113	# eshopts_push -o noglob
		114	# for x in ${foo} ; do
		115	# if ...some check... ; then

62	# This function is for bulk patching, or in theory for just one	192	# @FUNCTION: epatch
63	# or two patches.	193	# @USAGE: [patches] [dirs of patches]
		194	# @DESCRIPTION:
		195	# epatch is designed to greatly simplify the application of patches. It can
		196	# process patch files directly, or directories of patches. The patches may be
		197	# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
		198	# the -p option as epatch will automatically attempt -p0 to -p5 until things
		199	# apply successfully.
64	#	200	#
65	# It should work with .bz2, .gz, .zip and plain text patches.	201	# If you do not specify any options, then epatch will default to the directory
66	# Currently all patches should be the same format.	202	# specified by EPATCH_SOURCE.
67	#	203	#
68	# You do not have to specify '-p' option to patch, as it will	204	# When processing directories, epatch will apply all patches that match:
69	# try with -p0 to -p5 until it succeed, or fail at -p5.	205	# @CODE
70	#	206	# if ${EPATCH_FORCE} != "yes"
71	# Above EPATCH_* variables can be used to control various defaults,
72	# bug they should be left as is to ensure an ebuild can rely on
73	# them for.
74	#
75	# Patches are applied in current directory.
76	#
77	# Bulk Patches should preferibly have the form of:
78	#
79	# ??_${ARCH}_foo.${EPATCH_SUFFIX}	207	# ??_${ARCH}_foo.${EPATCH_SUFFIX}
		208	# else
		209	# *.${EPATCH_SUFFIX}
		210	# @CODE
		211	# The leading ?? are typically numbers used to force consistent patch ordering.
		212	# The arch field is used to apply patches only for the host architecture with
		213	# the special value of "all" means apply for everyone. Note that using values
		214	# other than "all" is highly discouraged -- you should apply patches all the
		215	# time and let architecture details be detected at configure/compile time.
80	#	216	#
81	# For example:	217	# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
		218	# for patches to apply.
82	#	219	#
83	# 01_all_misc-fix.patch.bz2	220	# Refer to the other EPATCH_xxx variables for more customization of behavior.
84	# 02_sparc_another-fix.patch.bz2
85	#
86	# This ensures that there are a set order, and you can have ARCH
87	# specific patches.
88	#
89	# If you however give an argument to epatch(), it will treat it as a
90	# single patch that need to be applied if its a file. If on the other
91	# hand its a directory, it will set EPATCH_SOURCE to this.

		451	# of these three directories to exist will be the one to use, ignoring
		452	# any more general directories which might exist as well.
		453	#
		454	# User patches are intended for quick testing of patches without ebuild
		455	# modifications, as well as for permanent customizations a user might
		456	# desire. Obviously, there can be no official support for arbitrarily
		457	# patched ebuilds. So whenever a build log in a bug report mentions that
		458	# user patches were applied, the user should be asked to reproduce the
		459	# problem without these.
		460	#
		461	# Not all ebuilds do call this function, so placing patches in the
		462	# stated directory might or might not work, depending on the package and
		463	# the eclasses it inherits and uses. It is safe to call the function
		464	# repeatedly, so it is always possible to add a call at the ebuild
		465	# level. The first call is the time when the patches will be
		466	# applied.
		467	#
		468	# Ideally, this function should be called after gentoo-specific patches
		469	# have been applied, so that their code can be modified as well, but
