I'm planning to make an implementation of Lua for the DLR, and i would like to use the listed Lua 5.1 grammar here. However i can't see a license that it was released under, so can someone please kindly point me in the direction of the license it uses?

Except for the lexical parts, the grammar looks like it's copied from the Lua reference manual, which is subject to the MIT license.

As it doesn't say (and a brief dig around the site doesn't indicate), the default state is that the copyright resides with the author. You'll have to contact him/her directly to use it legally.
