/*
* The code below can be used to make a Lua core that does not contain the
* parsing modules (lcode, llex, lparser), which represent 20% of the total core.
* You'll only be able to load binary files and strings, precompiled with luac.
* (Of course, you'll have to build luac with the original parsing modules!)
*
* To use this module, simply compile it and list its object file before the
* Lua libraries. The linker should then not load the parsing modules.
*
* If you want to avoid the dump module or the undump modules, use the
* corresponding #define below.
