Tim Smith (SourceForge site ops) asked me to file this report.
Debian uses a tool for checking versions of upstream software called uscan:
uscan relies on a HTML page with links to all released files (source tarballs etc) available for the upstream software in question. It detects version numbers by looking at filenames in link hrefs. For most projects that suffices. SourceForge does not currently provide such a HTML page. If you could provide something like the first URL below at the second URL (or similar) that would be helpful. For compatibility with the current code, the links should not have /download at the end of them like current links in the files interface do. It should be fine for the URLs to redirect to the final URL, fine for the URLs to be absolute links and fine to add any other content to the pages. The sort order does not matter, but should probably be sorted by date descending so humans reading the page get approximately the right order. If the page is added I will need to verify the existing uscan code is still compatible.
