OPTIONS
-O <level> Run the compiler with the given optimization level (>0: use precompiled .lua versions of Nomsu files, when available).
-v Verbose: print compiled lua code.
-c Compile the input files into a .lua files.
-e Execute the specified string.
-s Check the input files for syntax errors.
-I <file> Add an additional input file or directory.
-d <debugger> Attempt to use the specified debugger to wrap the main body of execution.
-h/--help Print this message.
--version Print the version number and exit.
--no-core Skip loading the Nomsu core by default.
-V specify which Nomsu version is desired.
<file> The Nomsu file to run (can be "-" to use stdin).
