Introduction

Defaults

Please note that module system allows to provide defaults on every level of module structure. So, there is :

• default DD for module imasenv  
• default UAL for module imasenv/<DD_ver> 
• default set of libraries for module imasenv/<DD_ver>/ual/<UAL_ver> 
• etc, etc

In this document under "default"  the versions of UAL and version of libraries set are meant.
