I guess I wasn't clear - I need to write out the precompiled chunk to
a file from within lua. 

In other words, with luac I can do this:

luac -o MyFile.luac -c MyFile.lua

and produce a MyFile.luac file that contains a precompiled version of
MyFile.lua. But could I do the same thing in lua without using a
system() call?
