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