+\fBnamespace unknown\fR ?\fIscript\fR?
+Sets or returns the unknown command handler for the current namespace.
+The handler is invoked when a command called from within the namespace
+cannot be found (in either the current namespace or the global namespace). 
+The \fIscript\fR argument, if given, should be a well
+formed list representing a command name and optional arguments. When
+the handler is invoked, the full invocation line will be appended to the
+script and the result evaluated in the context of the namespace. The 
+default handler for all namespaces is \fB::unknown\fR. If no argument
+is given, it returns the handler for the current namespace.
