useage: aspen [<options>] <path>

Options
    <path>
    The path to the aspen source file to execute

    -i or --interpret
    Execute the program using the tree walk implementation

    -l or --lex
    Do lexical analysis on the source code and print out the tokens scanned

    -p or --parse
    Parse the source code and print out the ast as an S-expression

    -t or --type-check
    Run the type checker on the program but do not execute it

Two implementations of Aspen are planned, a tree walk interpreter and a byte code vm. The -i flag is intended to select between which implementation to use. Currently only the tree walk interpreter has been implemented so this flag does nothing.
