/*
* The code below can be used to make a Lua core that does not contain the
* parsing modules (lcode, llex, lparser), which represent 35% 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 ("make noparser" does that) and list
* its object file before the Lua libraries. The linker should then not load
* the parsing modules. To try it, do "make luab".
*
* If you also want to avoid the dump module (ldump.o), define NODUMP.
* #define NODUMP
