precompile.sh [options] script
Compiles .py scripts into .mpy files, runs inside pycogame container

SCRIPT
    Path to micropython script, relative to code/ directory

OPTIONS
    -o  Optimisation level
        The optimisation level controls the following compilation features:
        - Assertions: at level 0 assertion statements are enabled and compiled 
          into the bytecode; at levels 1 and higher assertions are not compiled.
        - Built-in __debug__ variable: at level 0 this variable expands to True;
          at levels 1 and higher it expands to False.
        - Source-code line numbers: at levels 0, 1 and 2 source-code line number
          are stored along with the bytecode so that exceptions can report the 
          line number they occurred at; at levels 3 and higher line numbers are
          not stored.
        The default optimisation level is 3
    -h  Shows this help
