Revision: 21771
Author:   fingolfin
Date:     2006-04-10 15:45:05 -0700 (Mon, 10 Apr 2006)
ViewCVS:  http://svn.sourceforge.net/scummvm/?rev=21771&view=rev

Log Message:
-----------
More commented out stuff: added generateFilenameForDetection method, for use by the detector; and applied various fixes to generateFilename (which is still completely untested, so it certainly contains more 'bugs' :)
