#                 TEST FOR PPD FILE COMPLIANCE
#
# Keeping this up to date with changing CUPS versions is a real headache.
# This test, however, is particularly important; PPD conformance failures
# are one of the most frequently observed problems, and a lot of apps
# (and CUPS itself) are very sensitive -- arguably overly so -- to
# violations of the spec.
#
# We can't skip the translated PPD files either; sometimes translations
# blow out token maximum lengths.
