# AP_MKINCLUDE()
#
# Creates the file ap_include.am and sets the variable ap_include to
# point to this path. Now in your Makefile.am you can include
# ap_include.am by writing @ap_include@ on a line by itself.
#
# The file defines a pattern rule for making modes files, and a goal
# for installing the ones that have install="yes" in modes.xml. To
# generate modes, include a line like
#
# noinst_DATA=modes/$(PREFIX1).mode
#
# in your Makefile.am with _at most one mode_ (the others will be
# created even if you list only one, listing several will lead to
# trouble with parallell make).
#
# Install the modes by making install-data-local dependent on
# install-modes, ie.
#
# install-data-local: install-modes
#
# Also defined is a goal for making the .deps folder. If you want some
# file to be built in a folder named .deps, just make that goal
# dependent on .deps/.d, e.g.
#
# .deps/intermediate.dix: original.dix .deps/.d
