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.
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.
