I have updated the implementation to incorporate your feedback as much as possible while maintaining accuracy in the command descriptions. Now there is also a new help screen which can be invoked by typing '?'.

I am hoping the information in the new help screen will make the commands easier to understand. However, if you or anyone has better ideas about describing the commands, please feel free to send pull requests.

Thank you for playing with this tool and for offering your feedback! It has been very helpful in refining the command descriptions.
