This is our view too. We see no incompatibilities. Following the GNU
classification (http://www.fsf.org/licenses/license-list.html), we would
- Lua is free software
- Lua has no copyleft
- Lua is compatible with the GNU GPL
When we say, in our copyright, "... this implementation have been entirely
designed and written by...", the "this" refers to Lua, not the resulting
code. After all, this is the copyright of Lua, not the copyright of the
final product. If the wording can be improved please tell us how.
