* 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.
