I have a new sf.php that should solve the problem reported by Daniel. Also, it no longer accesses any sf.net mirror directly, because it uses the normal sf.net mirror selection system instead. The implemented algorithm is not exactly as described above, because I've learned more about uscan while coding this new sf.php. It's online available for testing. To see a list of files in your browser: http://qa.debian.org/~bartm/watch/sf.php/gtans To use this sf.php with uscan, first apply this patch to /usr/bin/uscan: http://qa.debian.org/~bartm/watch/uscan.diff Feedback is welcome.
