Your C program is linked to Lua (as a library), then it 
reads a configuration file using lua_open(), lua_load() 
or luaL_load...(), lua_pcall() and lua_close(). Before 
closing Lua, you can read Lua variables to set your 
options. Or you may prefer to lua_register() (just after 
lua_open) some C functions to be called by Lua, this way 
the options are set during the execution of your script.

Now that you have the outline, you'll understand the 
documentation better.
