Interfacing Otcl with C++ classes

[Ramesh Neelamani <neelsh@ruf.rice.edu>]

 Hello,

 I am unclear as to a basic issue which involves interfacing OTcl code with 
 a new C++ class which I create.

 The way to create the new TclObject is to derive from the TclClass. What 
 is unclear to me is that how is the new TclObject recognised within ns.
 I have read in the ns documentation that if I add a new .tcl file to be
 sourced in ~ns/tcl/lib/ns-lib.tcl it will automatically get sourced by ns 
 at startup.
 
 However I yet do not understand how I can "bind" the relevant .tcl file 
 to the new class which I have created in a .cc file.
 
 Thanks in advance,
 Amit Saxena.
