 It's written in Bash! Just open up the `abra` file and start hacking. Then you can run it in place with `./abra`. The command-line interface is generated via [docopt](http://docopt.org/). If you add arguments then you need to run `make docopt` ro regenerate the parser.

+Please remember to update the [CHANGELOG](./CHANGELOG) when you make a change.
