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

366 # apply successfully.

369 # directory specified by EPATCH_SOURCE.

372 # for this specific invocation. As soon as an arg w/out a dash is found, then
373 # arg processing stops.
375 # When processing directories, epatch will apply all patches that match:
377 # if ${EPATCH_FORCE} != "yes"

382 # The leading ?? are typically numbers used to force consistent patch ordering.
383 # The arch field is used to apply patches only for the host architecture with
384 # the special value of "all" means apply for everyone. Note that using values
385 # other than "all" is highly discouraged -- you should apply patches all the
386 # time and let architecture details be detected at configure/compile time.
