1 INTRODUCTION

The software decribed in this manual is intented to be used in the ESO VLT Project.

1.1 PURPOSE

This document is the User Manual of the code configuration system developed for the VLT Software project.

This manual documents both end-user commands and commands reserved to the Software Configuration Control Manager (SCCM).

The manual assumes that the reader is a software developer having a basic knowledge of UNIX and familiar with software development activities applying rules described in [2]

In addition to the Introduction section, this manual contains two major sections:

User's Guide. Describes the features of the configuration management module and includes examples of "how to use it"

Reference. Describes all the commands available to the user.

1.2 SCOPE

This manual describes version 1.69 and higher of the Configuration Management Module.

This system is a very basic one, handling only code modules. It does not encompass all software development actvities (for example, documentation). It even does not implement the complete code configuration system as described in [1].
