-The \function{Tcl} function is a factory function which creates an object
-much like that created by the \class{Tk} class, except that it does not
-initialize the Tk subsystem. This is most often useful when driving the Tcl
-interpreter in an environment where one doesn't want to create extraneous
-toplevel windows, or where one cannot (i.e. Unix/Linux systems without an X
-server). An object created by the \function{Tcl} object can have a Toplevel
-window created (and the Tk subsystem initialized) by calling its
-\method{loadtk} method.
