This fits my use case so perfectly! I have a very small internal app taking care of organizing seminar talks, calendars, email announcements, recordings of the talks, and signups. It is a single python file of less than 1500 lines and an sqlite database. This library is so perfect for taking care of scheduled events. Everything else I have found is ridiculously over-complicated of a solution.
I am a research scientist that knows how to write numerical code, but I do not trust myself to write secure web software. Which is the reason I regrettably keep the app in question internal and the source unreleased.
To give a more useful answer though: it just uses cherrypy as a web framework and the zoom python bindings and sqlite. Nothing sophisticated, just a CRUD app that occasionally needs to download a large file and transcoded it in the background (which is where this scheduler will be used).
