"""Pluggable exception handlers.
These are functions that take an exception as an argument and then return...
- the exception (in order to re-raise it)
- True (in order to continue and ignore the exception)
- False (in order to ignore the exception and stop processing)
They are used as handler= arguments in much of the library.
