# The overall procedure is to run make in this directory $(HERE) and then
# export it to a temporary directory $(EXPORTED) without all the generated
# files. On this directory we run "make ctanext" (see below) which makes a
# CTAN-compliant directory structure, and zips it up to the file
# <package>.ctan.zip which can be submitted to the CTAN maintainers.
#
# Note that part of the CTAN submission is a zip file with a TDS-compliant
# directory struture, which is generated by running "make tdsext" (see below)
# on $(EXPORTED).

# Note furthermore, that this Makefile only
