 /**
- * The interface that RSE system profiles implement.
+ * A system profile holds definitions for hosts
+ * (connections), filter pools, filters, and filter strings.
+ * It is the unit of persistence for those definitions. Individual
+ * hosts and filter pool definitions always reside in a profile and the profile
+ * itself is the entity that is saved and restored.
  * <p>
- * A profile represents a user or name which is used to key important user-data
- *  by:
- * <ul>
- *  <li>Hosts
- *  <li>Filter pools
- *  <li>User actions
- *  <li>Compile commands
- * </ul>
- * 
+ * Profiles may be active or inactive. An active profile contributes its
+ * definitions to RSE. When made inactive, it those definition are no longer 
+ * available for use.
