 Description:
 
 The model editor utility allows command-line and python-based editing of models.
 
-PATTERN is a regular expression used to match object or global names. PROPERTY
-and VALUE can be regular expressions or a property name and value tuple for
-get or set operations, respectively. When comma-separated patterns are
-allowed, they are interpreted as `and` operations. Note that the `add`
-command does not use regular expressions for NAME.

 Caveat:
 
 The model editor does not check whether the action will result in a faulty
-model, e.g., deleting a node that is referened by a link, add a property that
-is not valie for the class, or changing an object property to something invalid.
