/*
 * This module implements support for gathering and comparing available
 * printer information on a SVID or XPG4 compliant system.  It does this
 * through the use of the SVID/XPG4 command "lpstat(1)".
 *
 * The expectations is that execution of the command "lpstat -v" will
 * generate responses in the form of:
 *
 *	device for serial: /dev/term/b
 *	system for fax: server
 *	system for color: server (as printer chroma)
