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!

190# This function is for bulk patching, or in theory for just one 260# @FUNCTION: epatch
191# or two patches. 261# @USAGE: [patches] [dirs of patches]
262# @DESCRIPTION:
263# epatch is designed to greatly simplify the application of patches. It can
264# process patch files directly, or directories of patches. The patches may be
265# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
266# the -p option as epatch will automatically attempt -p0 to -p5 until things
267# apply successfully.
192# 268#
193# It should work with .bz2, .gz, .zip and plain text patches. 269# If you do not specify any options, then epatch will default to the directory
194# Currently all patches should be the same format. 270# specified by EPATCH_SOURCE.
195# 271#
196# You do not have to specify '-p' option to patch, as it will 272# When processing directories, epatch will apply all patches that match:
197# try with -p0 to -p5 until it succeed, or fail at -p5. 273# @CODE
198# 274# if ${EPATCH_FORCE} != "yes"
199# Above EPATCH_* variables can be used to control various defaults,
200# bug they should be left as is to ensure an ebuild can rely on
201# them for.
202#
203# Patches are applied in current directory.
204#
205# Bulk Patches should preferibly have the form of:
206#
207# ??_${ARCH}_foo.${EPATCH_SUFFIX} 275# ??_${ARCH}_foo.${EPATCH_SUFFIX}
276# else
277# *.${EPATCH_SUFFIX}
278# @CODE
279# The leading ?? are typically numbers used to force consistent patch ordering.
280# The arch field is used to apply patches only for the host architecture with
281# the special value of "all" means apply for everyone. Note that using values
282# other than "all" is highly discouraged -- you should apply patches all the
283# time and let architecture details be detected at configure/compile time.
208# 284#
209# For example: 285# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
286# for patches to apply.
210# 287#
211# 01_all_misc-fix.patch.bz2 288# Refer to the other EPATCH_xxx variables for more customization of behavior.
212# 02_sparc_another-fix.patch.bz2
213#
214# This ensures that there are a set order, and you can have ARCH
215# specific patches.
216#
217# If you however give an argument to epatch(), it will treat it as a
218# single patch that need to be applied if its a file. If on the other
219# hand its a directory, it will set EPATCH_SOURCE to this.

524# desire. Obviously, there can be no official support for arbitrarily
525# patched ebuilds. So whenever a build log in a bug report mentions that

533# level. The first call is the time when the patches will be
