Does what I need, so I can do what I like.
I'm slowly teaching my monkey to do all the chores that I don't like. Every now and then I teach it a new trick, but for now, here's what it can do...
Accounting
Banking
Small-business management
E-mail processing
Note: The published code does not do absolutely everything that is mentioned above, some things are still implemented as crude Rake scripts, using Monkey only as a Ruby library.
Monkey's primary interface is a self-documenting command-line application, but it can as well be used as a Ruby library. I personally use Monkey from pry whenever I want to do something that isn't supported by the command-line interface.
Here's how to get started:
bundle install
bundle exec bin/monkey
