I believe the general principle you want is this: For each module script...
1) Generate a header file that declares a constant byte array
containing the script data.
2) At a suitable point (i.e. after the Lua state has been opened & the
standard packages loaded, and before you run any other code), use
luaL_loadbuffer(L, buffer, sizeof(buffer)); to load from the byte
array.
3) Add the loaded function to the package.preload table. The table key
should be the name that require() will use to load the module.
