- new OSInet/Class_Grapher directory - moved misc.php and other miscellaneous PHP files to misc/ - split the PSR0 autoloader from misc.php to psr0.php - moved BackgroundApplication to FSM directory - moved FSM samples and docs to FSM help directory - new "apps" directory for the demo source - new Class_Grapher demo app - moved the files of the FSM FTP demo app to "apps". Likely broken.
