# description: HylaFAX(tm) is a sophisticated enterprise-strength fax
#              package for class 1 and 2 fax modems on unix systems.
#              This init script is the preferred way to start HylaFAX,
#              but does not, by default, activate any modems. Consult
#              the faxgetty(8) and faxmodem(8) man pages for more info.

The file $DIR_LIBDATA/setup.cache is not present.  This
