General

The basic layout of a configuration system is a system that has multiple targets (which may inherit from each other), every target can have some libraries, assemblies override clusters and normal clusters. Clusters can have sub clusters.

CONF_SYSTEM

Every configuration file describes one CONF_SYSTEM and has one or more CONF_TARGET associated. Normally a CONF_SYSTEM object is generated by parsing a configuration file with CONF_LOAD.

Implementation
