removing models from CUPS

[Paul Conklin]

Found a second symlink in /usr/lib/cups/driver, that fixed it.

> I removed the link from /usr/share/cups/model to the foomatic ppds and cycled cups, but I still see all the models in lpinfo -m as well as WI.  I also removed /var/cachec/cups/ppds.dat, but it came back with all the printers.  I just want "RAW" to be the only choice, what else do I need to remove / clean up?  CUPS 1.4.7 on RHEL
