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 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!

222 vapier 1.322 # @DESCRIPTION:
223     # Often times code will want to enable a shell option to change code behavior.
224     # Since changing shell options can easily break other pieces of code (which
225     # assume the default state), eshopts_push is used to (1) push the current shell
226     # options onto a stack and (2) pass the specified arguments to set.
227     #
228 vapier 1.330 # If the first argument is '-s' or '-u', we assume you want to call `shopt`
229     # rather than `set` as there are some options only available via that.
230     #
231 vapier 1.322 # A common example is to disable shell globbing so that special meaning/care
232     # may be used with variables/arguments to custom functions. That would be:
233     # @CODE
234 vapier 1.438 # eshopts_push -o noglob

377     # The arch field is used to apply patches only for the host architecture with
378     # the special value of "all" means apply for everyone. Note that using values
379     # other than "all" is highly discouraged -- you should apply patches all the
