<p>A human-readable summary of the packages available in this repository can be found in <a href="/SUMMARY.txt"><code>SUMMARY.txt</code></a>, which is automatically generated from the source packages in the repo.</p>
<p>Note that while older versions of packages <em>do</em> exist in this repository, they are not guaranteed to stick around - as they may be cleared out periodically (todo: automatically clear out packages older than ~2-3 versions behind) to save on disk space.</p>
<p>Note that while older versions of packages <em>do</em> exist in this repository, packages more than 3 versions out of date are now automatically deleted to save on disk space. If you need really old versions, download them and keep them as backups ☺</p>
<p>Finally, as many CPU architectures will be attempted to be supported here as possible. If binary packages are being released by a project, they are probably packaged here. The exception to this is the 32-bit x86 architecture. This is deprecated by many Linux distributions - so effort is not made to package it here (though if you've got a valid use-case get in touch and I'll see if I can help).</p>
