Hi Manuel. Excerpts from Manuel M T Chakravarty's message of Dom Fev 14 22:38:12 -0200 2010: (...)

...

I notice that the c2hs manual from c2hs-0.16.0 is licensed under GFDL, which is not free according to the Debian Free Software Guidelines. I'd like to ask the c2hs developers to distribute the manual under a license that is compatible with DFSG, otherwise we'll have the following alternatives:

* Move the c2hs to the non-free area of the archive. * Remove the manual from the c2hs package, possibly creating a package containing the manual in the non-free area.

Is the license change possible?

How about CC-BY-SA? (...) Is that ok for Debian?

Yes for CC-BY-SA 3.0[1], no for CC-BY-SA 2.5[2].

I believe that I still hold the sole copyright of the c2hs manual and I'm happy to relicense it under the CC-BY-SA if that would solve your problem.

This thread continued in debian-haskell without replying to here too (sorry about that). As noticed in [3], this change is not needed, but still encouraged. So, if you could do this, it would be great, but it's not necessary.
