I did my best to be transparent about it.  I made sure to email this
list, haskell-cafe, haskell, and the libraries list asking if anyone
had heard from Sven.  I waited about a month before taking action.  He
still hasn't reappeared.

I have no desire to take control by force but I do think Sven has
effectively stopped maintaining these libraries and I don't want to
see them disappear.  Do you have advice on what I should have done
differently?

The only actions I've taken at this point are:
  * Declaring myself maintainer
  * Putting the repos on github
  * Updating the Haskell wiki to point to github
  * Creating a haskell-opengl organization on github to organize the
development efforts

The Haskell-opengl org is here, if anyone on this list wants to join
please send me an email:
https://github.com/haskell-opengl

One of the things I have NOT done yet is to upload new versions of the
libraries to hackage.  I thought I would wait a bit longer than just a
month before doing that in case announcing a new maintainer prompted
Sven to reappear.  It would be good to upload some bug fixes soon-ish
though.

Maybe we can get your frame buffer objects in to the newer bindings?

Thanks,
