When you download the file from http://luaforge.net/frs/?group_id=340&release_id=1112
what is the part you need? If it is just the 'concurrent' directory that is all Lua I can add it immediately. But there are other parts and I am not sure what you need. Please let me know.
It is hard for us (the Lua for Windows developers) to add modules that we don't know what they do or how to build them. Help is always appreciated.
