Executive Summary

This is a TUI abacus simulator. It is a completely pointless program. I made it solely for the sake of the absurdity.

Installation

This program is written in Haskell using the Stack package manager. The easiest way to install it is by first installing GHCup, and then from within the project directory, run the command: stack install

You should then be able to run it by simply typing abacus on the command line. There are currently no command-line options.
