scpm is something like the Location Manager for Mac OS X. You need to be root to execute most of its commands: /sbin/scpm list
Lists all available profiles. /sbin/scpm switch "profilename"
Switches to the specified profile. /sbin/scpm add "newprofilename"
Adds a new profile based on the present systems settings. The files subject to change are located in /var/lib/scpm/profiles/"profilename"/file and /var/lib/scpm/profiles/"profilename"/service. But you shouldn't modify them manually. I addition you can make arbitrary changes via scriptfiles that are executed upon changing the profile.
