   4 * The code below can be used to make a Lua core that does not contain the
   5 * parsing modules (lcode, llex, lparser), which represent 35% of the total core.
   6 * You'll only be able to load binary files and strings, precompiled with luac.
   7 * (Of course, you'll have to build luac with the original parsing modules!)
   8 *
   9 * To use this module, simply compile it ("make noparser" does that) and list
  10 * its object file before the Lua libraries. The linker should then not load
  11 * the parsing modules. To try it, do "make luab".
  12 *
  13 * If you also want to avoid the dump module (ldump.o), define NODUMP.
  14 * #define NODUMP
