   1 /*
   2 * The code below can be used to make a Lua core that does not contain the
   3 * parsing modules (lcode, llex, lparser), which represent 35% of the total core.
   4 * You'll only be able to load binary files and strings, precompiled with luac.
   5 * (Of course, you'll have to build luac with the original parsing modules!)
   6 *
   7 * To use this module, simply compile it ("make noparser" does that) and
   8 * list its object file before the Lua libraries. The linker should then not
   9 * load the parsing modules. To try it, do "make luab".
