No workaround ?

I understand that using one mirror directly is a temporary approach that should
be replaced by something going via the sourceforge mirror-selection system.
This can be solved for debian/watch files using
http://sf.net/<projectname>/<filenamebase>-(.*)\.tar\.gz and similar, by
enhancing the sf.net redirector with the following algorithm:

- Access http://sourceforge.net/projects/<projectname>
  Parse the html to find the value of the group_id.
- Access http://sourceforge.net/project/showfiles.php?group_id=...
  Parse the html to find the values of the package_id's.
- For each package_id:
  - Access 
http://sourceforge.net/project/showfiles.php?group_id=...&package_id=...
    Parse the html to verify whether it contains files matching
    the pattern <filenamebase>-(.*)\.tar\.gz.
  - If it does contain files matching, then find the filename with the
    highest version number.  This is a preliminary result.
- After processing all package_id's, select the preliminary result with the
  highest version number.  This is the final result.

So far what to do to make the existing debian/watch files continue to work
without depending on the only sf.net mirror that keeps the redirector currently
working.

Later on, a nice-to-have would be support for specifying a package_id in
debian/watch, so that the searching for the newest upstream release can be
limited to only one sf.net package within the sf.net group, instead of all
packages in the group.
