A few more thoughts: You might check out the Luai version of the Manual, which incorporates all errata. <http://pgl.yoyo.org/luai/i/about>. That page links to: <http://lua-users.org/wiki/LuaHelp>. A script for parsing the manual. There is also <http://math2.org/luasearch/>, which collects the documentation for some of the modules. Best regards, Paul
