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