This is a mixin which adds an example to the path, tests it, and then
removes it from the path and unimports the modules which the test loaded.
Test cases which test example code and documentation listings should use
this.
This is done this way so that examples can live in isolated path entries,
next to the documentation, replete with their own plugin packages and
whatever other metadata they need. Also, example code is a rare instance
of it being valid to have multiple versions of the same code in the
repository at once, rather than relying on version control, because
documentation will often show the progression of a single piece of code as
features are added to it, and we want to test each one.

The example script prints a usage message to stdout if it is
passed a --help option and then exits.
The first line should contain a USAGE summary, explaining the
accepted command arguments.
