+After the \fItargetObject\fR has been created and all definitions of its
+configuration (e.g., methods, filters, mixins) copied, the \fB<cloned>\fR
+method of \fItargetObject\fR will be invoked, to allow for customization of
+the created object such as installing related variable traces. The only
+argument given will be \fIsourceObject\fR. The default implementation of this
+method (in \fBoo::object\fR) just copies the procedures and variables in the
+namespace of \fIsourceObject\fR to the namespace of \fItargetObject\fR. If
+this method call does not return a result that is successful (i.e., an error
+or other kind of exception) then the \fItargetObject\fR will be deleted and an
+error returned.
