13 # home rather than having multiple ebuilds implementing the same thing.
15 # Due to the nature of this eclass, some functions may have maintainers

356 # epatch is designed to greatly simplify the application of patches. It can

360 # apply successfully.

363 # directory specified by EPATCH_SOURCE.

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

371 # if ${EPATCH_FORCE} != "yes"

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
380 # time and let architecture details be detected at configure/compile time.
