# Find the PPD files delivered by foomatic that Solaris does not support.
# There are two reasons for non-support:
#
#	1. license/patent issues with the driver (listed in file nolicense). These
#	   files are removed and not delivered
#	2. The driver used by the PPD file must be brought downand compiled and
#	   Solaris has not chosen to do so. In that case the PPD file is delivered,
#	   but not included in the generated cache file.
#
# The unsupported PPD file should be listed in $BUILD_DIR/ppdunsupported for
# review. The catchall file, ppdsnomatch, should be empty. If not, a new
# case is needed in this script. The other files are there for debugging
# purposes.

# Notes:
#	drivers come in several flavors: gs built in, gs uniprint, postscript,
#	hpijs, and then the several other drivers.
# Drivers are noted in many PPD files with driverType. To sort these, look
# for:	driverType G/GhostScript built-in:
#	driverType U/GhostScript Uniprint:
#	driverType F/Filter: "" 
# Drivers are also noted in the name of the ppd file. This is used
# to cull out postscript, hpijs, and pxlmono . These do not reliably
# use driverType. note: pxlmono driver is a gs built-in but many of the
# ppd files that use this driver do not utilize the driverType line.
# driverType I/IJS: "" is not reliable for hpijs as not used in many ppds.
 
# driverType F/Filter: "" denotes ppd files that use GhostScript and
# then pipe that output to one or more other drivers. These will only be 
# supported if Solaris compiles and delivers these drivers.

# Make sure that there are no undefined variables
