Usage:  jai build.jai - [OPTIONS] :: [PROGRAM ARGS]

Options:
    help        Prints this help menu.
    silent      Disables compiler/linker statistics.
    run         Runs your program afterwards.
    release     Builds with release options. If omitted, it builds a debug build.
    memory      Enables the memory leak detector.

Passing Args to your Program:
    If you want to supply args to your program, pass it like that:

        `jai build.jai - run :: my_arg1 foo bar abc ABC`

    Everything after the `::` get's forwarded to your program.
