sanitize-ppd-names

#!/bin/sh

# Sometimes contributed PPD files can have ugly file names, containing
# spaces or other special characters which are difficult to handle in
# shell scripts. Therefore it is recommended to run this script after
# each commit of PPD files to sanitize the file names.
#
# Also rename uppercase .PPD extensions into lowercase .ppd
#
# When in the colned GIT repo the renaming is done with "git mv" so
# that it can easily be applied with "git commit" afterwards.
#
# The script can also be run in a downloaded release, for example for
# packaging for a Linux distribution. Then a simple "mv" is used.
