Hi Andrey,

Project:M36 is a complete relational algebra engine with multiple
front-ends, optional filesystem persistence, and transactional
semantics. Therefore, it is more akin to SQL DBMSs.

More specifically, IxSet does not support relational join, relational
group, persistence, aggregations, schema changes, or transactions.
Acid-state is effectively a structure graph serializer and therefore has
no provisions for schema changes, querying, or any relational algebra

Project:M36 can be used as a foundational component of the "Out of the
Tarpit" architecture, while the other packages cannot.
