"""
The ``interface`` taxon is the most fundamental and generic applet taxon. It groups applets
implementing interfaces that are used for purposes that do not fit into any single other taxon.

Because the ``interface`` taxon is so important, the applet names in this taxon are not prefixed
with the taxon name.

The ``memory`` taxon groups applets implementing interfaces to memory technology devices (volatile
and non-volatile) that include no functionality beyond manipulating data.
