Agreed!

My pet peeve: open source packages that have no separation of the actual IP from the embodiment in an app or environment. Is it so hard to create a library? And put the real feature in there, instead of wrapped up in some run-on main module?

Kudos to this writer for doing it well.

Thank you both! I too like the Unix philosophy of small tools that do a specific job. In a package like this, people may find they only care about one or two tools. They can ignore the rest and mix and match with other tools as they see fit.
