-# @FUNCTION: eshopts_push
-# @USAGE: [options to `set` or `shopt`]
-# @DESCRIPTION:
-# Often times code will want to enable a shell option to change code behavior.

-# options onto a stack and (2) pass the specified arguments to set.
-#
-# If the first argument is '-s' or '-u', we assume you want to call `shopt`
-# rather than `set` as there are some options only available via that.
-#
-# A common example is to disable shell globbing so that special meaning/care
-# may be used with variables/arguments to custom functions. That would be:
-# @CODE
-# eshopts_push -o noglob
-# for x in ${foo} ; do
-# if ...some check... ; then
-# eshopts_pop
-# return 0
-# fi

-# @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.
