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 swegener 1.286 #
15 vapier 1.283 # Due to the nature of this eclass, some functions may have maintainers
16     # different from the overall eclass!

151 vapier 1.322 # @DESCRIPTION:
152     # Often times code will want to enable a shell option to change code behavior.
153     # Since changing shell options can easily break other pieces of code (which
154     # assume the default state), eshopts_push is used to (1) push the current shell
155     # options onto a stack and (2) pass the specified arguments to set.
156     #
157 vapier 1.330 # If the first argument is '-s' or '-u', we assume you want to call `shopt`
158     # rather than `set` as there are some options only available via that.
159     #
160 vapier 1.322 # A common example is to disable shell globbing so that special meaning/care
161     # may be used with variables/arguments to custom functions. That would be:

272 vapier 1.325 # @DESCRIPTION:
273     # epatch is designed to greatly simplify the application of patches. It can
274     # process patch files directly, or directories of patches. The patches may be
275     # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
276     # the -p option as epatch will automatically attempt -p0 to -p5 until things
277     # apply successfully.

280     # directory specified by EPATCH_SOURCE.

283     # for this specific invocation. As soon as an arg w/out a dash is found, then
284     # arg processing stops.

291     # *.${EPATCH_SUFFIX}
292     # @CODE
293     # The leading ?? are typically numbers used to force consistent patch ordering.
294     # The arch field is used to apply patches only for the host architecture with
295     # the special value of "all" means apply for everyone. Note that using values
296     # other than "all" is highly discouraged -- you should apply patches all the
297     # time and let architecture details be detected at configure/compile time.
