Preface
October 1980

This document describes configurations of the Alto/Mesa system software and the individual components which comprise them. These components include runtime support for the language, routines for manipulating the Alto display, keyboard, and file system, facilities for loading client programs and building new systems, and a number of useful common software packages.

Suggestions as to the form, correctness, and understandability of this material should be funneled through your support group. All of us involved in the development of Mesa welcome feedback and suggestions on the language, the system, and the debugging environment.
