An alternative CUPS rc script & toggle script, which enables CUPS to run on production boxes which usually read-only mount /usr (and /usr/local). Items in /usr, /dev & /etc aren't altered with each CUPS start/box boot. For print servers running cupsd, not for clients using cups_browsed. Inspiration taken from the postfix-{enable,disable,install} scripts, with much code copied from the cupsd rc script and into 'cups-toggle (enable|disable)'. See: http://marc.info/?t=143422329000001
