Essay

For more background on this project, read the blog post I wrote about developing it.

Prerequisites

You'll need to install:

• haskell, a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing.
• stack, a cross-platform program for developing Haskell projects.

Playing solitaire

You can clone this repo and use stack to build and run the executable like so:

git clone https://github.com/ambuc/solitaire.git
cd solitaire
stack build
stack exec solitaire-exe
