Is it possible to modify a Github repo's contents at a previous commit and then link to that modified commit in requirements.txt?
<p>I'm currently pulling in a repo at a previous commit with:</p>

<pre><code>git+git://github.com/username/application-name.git@357y3530u325#egg=application-name
</code></pre>

<p>I want to modify some code at that commit, so I have forked the repo.  </p>

<p>Is it possible to modify a Github repo's contents at a previous commit and then link to that modified commit in requirements.txt? </p>

<p>It would be good if I could do it all via the Github website, as opposed to cloning to local, modifying and pushing etc, if that is possible.  </p>
