+		 * PROBLEM: the config file MUST be readable in the specified location...
+		 * once it is moved, the site config needs to be updated to point at the 
+		 * new location... we could throw an error here, explaining that the 
+		 * file needs to be moved manually, but if the user upgrades to the NEXT 
+		 * version, the system would believe that there's a problem because the 
+		 * config file would be MISSING (they'd have to go through setup all over
+		 * again, even though they have an existing WORKING db)...
+		 * 
+		 * STEPS THAT NEED TO OCCUR:::
+		 * 1.) move the config file to /rw/config.xml from /lib/config.xml
+		 * 2.) ensure the site_config points to the CURRENT config file
+		 * 		OPTIONS:
+		 * 			a.) set "trigger" to look for old config when rw/config.xml
+		 * 				is missing & do the proper change (must be set prior 
+		 * 				to the upgrade/setup system checks)
+		 * 					++ ALPHA3 -> ALPHA4 would work
+		 * 					-- potentially breaks future upgrades
+		 * 					-- bypasses upgrade system
+		 * 			b.) scriptify direct modification of the site_config.php file
+		 * 				so it points to the new location during this upgrade
+		 * 					++ ALPHA3 -> ALPHA4 would work
+		 * 					++ doesn't bypass upgrade system
+		 * 			c.) drop all auto-upgrades prior to this one (ALPHA4), with 
+		 * 				moving the config file being the FIRST step, then run 
+		 * 				ALL other changes; it's an ALPHA, so things are 
+		 * 				expected to possibly be hairy.
+		 * 					-- developers running pre-ALPHA4 will have problems
+		 * 					++ ALPHA3 -> ALPHA4 would work
+		 * 					++ doesn't bypass upgrade system
+		 * 3.) systems upgrading from 1.1 must be able to do so automatically.
+		 * 
+		 * PROBLEMS:
+		 * 1.) setup MUST know where current config file is: if it is pointing 
+		 * to the NEW location and it exists in the OLD, setup will run; if it 
+		 * is pointing to the OLD location but it's in the NEW, setup will run.
+		 * 		a.) if 1.2 (post-ALPHA4) always expects config to be in the new
+		 * 			location, those caught in the mix can just manually move it
+		 * 			to the new location
+		 * 		b.) no reason to believe it would EVER point to the old location 
+		 * 			when there's one in the new location.
+		 * 
+		 * 
+		 * TODO: remove support for pre-alpha4 installs
+		 * TODO: consolidate pre-alpha4 changes into alpha4 upgrade
+		 * TODO: warn existing developers of changes and how to manually upgrade (update to r{x}, let setup run, update db + VERSION file)
