"""This is the top-level M2-ISA-R package. The project is divided into three major parts:
* :mod:`m2isar.metamodel`, the metamodel classes and helpers.
* :mod:`m2isar.backends`, consumers of M2-ISA-R models. Provided are an architecture plugin
generator for ETISS and a graphical tool to inspect M2-ISA-R models.
* :mod:`m2isar.frontends`, producers of M2-ISA-R models. Currently provided is a parser for
CoreDSL 2 ISA models.
