How about something like this:

	set substitute-path [<path>]
		If this variable is set, <path> is a colon-separated
		list of <from>,<to> pairs.  When a full path that
		has been encoded in the debug information is processed,
		each <from>,<to> pair is applied by searching the full
		path for the <from> string and replacing it by the <to>
		string.  If <path> is not used, then the substitute-path
		variable is un-set.

	show substitute-path
		Display the current list of <from>,<to> pairs.
