The use_namespace name TCL command searches for all TCL commands of the form name.x, and creates a new TCL command x that calls name.x. This allows a simple “dump” of Eco Lab model methods and instance variables into TCL's current namespace. The term “namespace” in use_namespace is unrelated to TCL's namespace concept.

Note that use_namespace does not override an any existing commands in the current namespace. Imagine what havoc an instance variable called “proc” would make! Thus it may be necessary to refer to an instance variable or method by its fully qualified name fro TCL scripts to get the desired behaviour.
