I agree with Nicolas. In general it is better to do it by hand to make sure it's safe and efficient.
However, automated wrapper generators exist, like Swig for example. It could be interesting to have a translator for Swig to generate Neko libs. Then libs which are wrapped for swig would be automatically available for Neko. Never tried myself, I don't know how good it is. Cheers. -- David -- Neko : One VM to run them all (http://nekovm.org)
