# Revision 1.5  2003/03/29 13:08:28  jalet
# Configuration is now expected to be found in /etc/pykota.conf instead of
# in /etc/cups/pykota.conf
# Installation script can move old config files to the new location if needed.
# Better error handling if configuration file is absent.
#
# Revision 1.4  2003/03/29 09:47:00  jalet
# More powerful installation script.
#
# Revision 1.3  2003/03/26 17:48:36  jalet
# First shot at trying to detect the availability of the needed software
# during the installation.
#
# Revision 1.2  2003/03/09 16:49:04  jalet
# The installation script installs the man pages too now.
#
# Revision 1.1  2003/02/05 21:28:17  jalet
# Initial import into CVS
