Introduction
------------

BlockingScheduler is the simplest possible scheduler. It runs in the foreground, so when you call
:meth:`~apscheduler.schedulers.blocking.BlockingScheduler.start`, the call never returns.

BlockingScheduler can be useful if you want to use APScheduler as a standalone scheduler (e.g. to build a daemon).
