Is it possible to commit to a project in the Attic?

[Gregory (Grisha) Trubetskoy]

If someone wanted to fix a bug or finish a feature or resolve a Jira issue 
on a project that is currently in the attic (speicifically I'm referring 
to mod_python in this case), what is the ASF policy on that?

Do we have a process by which contributions could still be accepted from 
former committers (or outside, provided that at least one member of the 
former PMC is around to vet), even if perhaps such a project may not see a 
release in any forseable future, or is the only option available is to 
fork the project somewhere outside of ASF (e.g. Github) and do it there?

In this particular case a number of fixes have been made over the years by 
various other parties (distro vendors, etc), and they are not reflected in 
SVN but are rather scattered across the web. Seems like it wouild be of 
general benifit to humanity to have them consolidated if someone would be 
willing to put in the time.

Thank you,

Grisha
