-e stat
       execute statement stat.  You need to quote stat if it contains spaces, quotes, or other characters
       special to the shell.
-i     enter interactive mode after script is executed.
-l file
       call require(file) before executing script.  Typically used to load libraries  (hence  the  letter
       l).
-v     show version information.
-P     suppress  the  creation of a standard LUA_PATH variable. Use this if you need to run scripts which
       conflict with system-installed libraries.
