+* 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.
