526# @DESCRIPTION:
527# Applies user-provided patches to the source tree. The patches are
528# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
529# of these three directories to exist will be the one to use, ignoring
530# any more general directories which might exist as well.
531#
532# User patches are intended for quick testing of patches without ebuild
533# modifications, as well as for permanent customizations a user might
534# desire. Obviously, there can be no official support for arbitrarily
535# patched ebuilds. So whenever a build log in a bug report mentions that
536# user patches were applied, the user should be asked to reproduce the
537# problem without these.
538#
539# Not all ebuilds do call this function, so placing patches in the
540# stated directory might or might not work, depending on the package and
541# the eclasses it inherits and uses. It is safe to call the function
542# repeatedly, so it is always possible to add a call at the ebuild
543# level. The first call is the time when the patches will be
544# applied.
545#
546# Ideally, this function should be called after gentoo-specific patches
547# have been applied, so that their code can be modified as well, but
548# before calls to e.g. eautoreconf, as the user patches might affect
549# autotool input files as well.

1236# strace -elseek <pdv archive>
