# SETFILES is set to an XML file with a list of all xml and image files

# Generating this list is very time consuming and is the main time factor
# when parsing the Makefile. Therefor we absolutely want to make sure it is
# only called once! We achieve this by writing thresult to a
# temporary file that is deleted when exiting DAPS.
#
# This file can be used as an input source for the actual file list generating
# stylesheet (extract-files-and-images.xsl).
# That stylesheet only takes a few miliseconds to execute, so we can afford to
# run it multiple times (SRCFILES, USED, projectfiles).
