 *      PACKAGE:  [incr Tcl]
 *  DESCRIPTION:  Object-Oriented Extensions to Tcl
 *
 *  [incr Tcl] provides object-oriented extensions to Tcl, much as
 *  C++ provides object-oriented extensions to C.  It provides a means
 *  of encapsulating related procedures together with their shared data
 *  in a local namespace that is hidden from the outside world.  It
 *  promotes code re-use through inheritance.  More than anything else,
 *  it encourages better organization of Tcl applications through the
 *  object-oriented paradigm, leading to code that is easier to
 *  understand and maintain.
 *  
 *  ADDING [incr Tcl] TO A Tcl-BASED APPLICATION:
 *
 *    To add [incr Tcl] facilities to a Tcl application, modify the
 *    Tcl_AppInit() routine as follows:
 *
 *    1) Include this header file near the top of the file containing
 *       Tcl_AppInit():
 *
 *         #include "itcl.h"
 *
 *    2) Within the body of Tcl_AppInit(), add the following lines:
 *
 *         if (Itcl_Init(interp) == TCL_ERROR) {
 *             return TCL_ERROR;
 *         }
 * 
 *    3) Link your application with libitcl.a
 *
 *    NOTE:  An example file "tclAppInit.c" containing the changes shown
 *           above is included in this distribution.
