Re: [Glsdk-devel] util. lib brainstorming

[Branan R. <br...@gm...>]

If no one else has gotten in touch with the GLFW people yet, I'll get
in touch with them, talk to them about our design goals for the SDK,
and see if we can integrate them into our SVN (maybe using svn
externals on a stable tagged version so we don't actually duplicate
anything)
