The Main Entry Point

Every binary executable package must define a Main function with no parameters. By default, this file is called Main.rux. The returned int becomes the process exit code; by convention 0 means success.

// Entry point
func Main() -> int {
    return 0;
}

A non-zero return value signals failure, following the usual operating-system convention. Only a binary executable package needs a Main; a library package has none.
