1 INTRODUCTION

1.1 PURPOSE

This manual provides a brief overview of the VLT Common Software and a roadmap to the VLT Software documentation.

The document is intended for designers of VLT applications, both inside and outside ESO, to get a first global idea about the VLT Common Software. For more information on a specific subject, please refer to the appropriate documentation.

1.2 SCOPE

The VLT Common Software is a set of basic tools needed for development of VLT Applications on Workstations orLCUs, namely:

· a set of utilities for the application of standards to code and document development

· the LCU Common Software (LCC)

· drivers for the standard LCU boards

· the Motion Control

· the Workstation Common Software (CCS)

· the Instrumentation Common Software

(This VLT Common Software described in the present documents is available from the JULY 95 release onward).
