447# @FUNCTION: epatch_user
448# @USAGE:
449# @DESCRIPTION:
450# Applies user-provided patches to the source tree. The patches are
451# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
452# of these three directories to exist will be the one to use, ignoring
453# any more general directories which might exist as well.
454#
455# User patches are intended for quick testing of patches without ebuild
456# modifications, as well as for permanent customizations a user might
457# desire. Obviously, there can be no official support for arbitrarily
458# patched ebuilds. So whenever a build log in a bug report mentions that
459# user patches were applied, the user should be asked to reproduce the
460# problem without these.
461#
462# Not all ebuilds do call this function, so placing patches in the
463# stated directory might or might not work, depending on the package and
464# the eclasses it inherits and uses. It is safe to call the function
465# repeatedly, so it is always possible to add a call at the ebuild
466# level. The first call is the time when the patches will be
467# applied.
468#
469# Ideally, this function should be called after gentoo-specific patches
470# have been applied, so that their code can be modified as well, but
471# before calls to e.g. eautoreconf, as the user patches might affect
472# autotool input files as well.
