what is the difference between write and WRITE?

What this code is doing is intercepting/overwriting
the global write() and output() symbols.

The wrapper version of write buffers all the lines
so that they can be processed in post_output_hook.

This line is making copies of the original write and output
function before they are overridden.

WRITE() is the original write() as defined by tolua.
This script has its own write global that overrides it.

This is still very unreadable.  Sounds like switching the lua to a few lines of
python would be much better.

[Sam Clegg, 2013-03-09 01:25:46]

Post processing is now done by post_process.py.

basic.lua renamed tolua_preload.lua to more accurately 
reflect what it is.
