Hi!
I would like to propose an update of ruby-opengl for wheezy to remove
documentation without clear license.
Please find below the changelog entry and in attachment the full
debdiff.
-----8<---------------------------------
ruby-opengl (0.60.1+dfsg2-1~wheezy1) stable; urgency=medium
* Imported Upstream version 0.60.1+dfsg2
* Repack upstream tarball to remove examples/NeHe as it does not have a
clear license (Closes: #713820).
* Do not rely on Rake file to clean.
-- Cédric Boutillier <boutil@debian.org> Sun, 26 Jan 2014 15:00:58 +0100
----->8---------------------------------
With kind regards,
Cédric
