"""This is the ETISS architecture generation backend of M2-ISA-R. It is used
for automatic generation of architecture plugins for the ETISS instruction
set simulator.

The main entry point for the architecture plugin writer is contained within
:mod:`m2isar.backends.etiss.writer`. Several helper modules in this package
encapsulate the required functionality for outputting complete ETISS architecture
plugins.
