+ * This module implements support for gathering and comparing available

+ * 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)
