I guess a more meaningful title would be "Cement – A Python Framework for building CLI applications".
A very good suggestion, I had no idea that was what it was - also the word "Ninja" is non-descriptive, has negative connotations, links to "cowboys" in various industries (and more)... I actually closed the tab straight away - I have a busy day ahead and don't want to spend time wading through "cool" words to work out what something is. Hope that is helpful!
