Spaceman — A Whitespace Implementation
--------------------------------------

Spaceman is a whitespace interpreter written in Haskell. It uses Megaparsec for
parsing purposes and a simple stack  machine that reflects the operation of the
whitespace language.


Quickstart:

    % cabal configure
    % cabal build
    % cabal run spaceman -- ./examples/hello-world.ws
    Hello World!
    % cabal run spaceman -- ./examples/count.ws

            Instructions:

    Please enter a 9x9 grid of numbers (0-9).
    Do not put spaces between the numbers.
    '0' represents an empty cell:

    530070000
    600195000
    098000060
    800060003
    400803001
    700020006
    060000280
    000419005
    000080079

    Please be patient.
    Easy sudokus typically take a minute or two on my Core 2 Duo.
