New Revision: 6535

Modified:
   trunk/tools/download-redirector-v2/scanner/scanner.pl
Log:
scanner: 
- remove dead code, and remove obsolete options from the program help
- when scanning all mirrors, start with those that have been scanned longest ago
- in parallel scan, don't clutter output when no error occured
