+# @BLURB: many extra (but common) functions that are used in ebuilds
+# @DESCRIPTION:
+# The eutils eclass contains a suite of functions that complement
+# the ones that ebuild.sh already contain.  The idea is that the functions
+# are not required in all ebuilds but enough utilize them to have a common
+# home rather than having multiple ebuilds implementing the same thing.
+#
+# Due to the nature of this eclass, some functions may have maintainers
+# different from the overall eclass!

+# @FUNCTION: epatch
+# @USAGE: [options] [patches] [dirs of patches]
+# @DESCRIPTION:
+# epatch is designed to greatly simplify the application of patches.  It can
+# process patch files directly, or directories of patches.  The patches may be
+# compressed (bzip/gzip/etc...) or plain text.  You generally need not specify
+# the -p option as epatch will automatically attempt -p0 to -p4 until things
+# apply successfully.
+#
+# If you do not specify any patches/dirs, then epatch will default to the
+# directory specified by EPATCH_SOURCE.
+#
+# Any options specified that start with a dash will be passed down to patch
+# for this specific invocation.  As soon as an arg w/out a dash is found, then
+# arg processing stops.
+#
+# When processing directories, epatch will apply all patches that match:
+# @CODE
+#	if ${EPATCH_FORCE} != "yes"
+#		??_${ARCH}_foo.${EPATCH_SUFFIX}
+#	else
+#		*.${EPATCH_SUFFIX}
+# @CODE
+# The leading ?? are typically numbers used to force consistent patch ordering.
+# The arch field is used to apply patches only for the host architecture with
+# the special value of "all" means apply for everyone.  Note that using values
+# other than "all" is highly discouraged -- you should apply patches all the
+# time and let architecture details be detected at configure/compile time.
+#
+# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
+# for patches to apply.
+#
+# Refer to the other EPATCH_xxx variables for more customization of behavior.

+# User patches are intended for quick testing of patches without ebuild
+# modifications, as well as for permanent customizations a user might

+# Ideally, this function should be called after gentoo-specific patches
