Product Design Documents

Richard Brooksby, Ravenbrook Limited, 2002-05-23

1. Introduction

This is the catalogue of design documents of the Memory Pool System product.

This is not a complete set of design documents for the MPS. We have many hundreds of documents, many of which contain confidential information. We are sorting through these and will include more as time goes on. We have tried to select the key documents for inclusion in the open source release, by including those documents referenced by the source code.

This document will be modified as the product is developed.

The readership of this document is the product developers.

This document is not confidential.
