tclTCP+ is an extension of Kevin Kenny's original tclTCP package.
The extensions are highlighed with change bars in the on-line man
page (tcp.n).  The original copyright as well as Parallelograms
copyright appear in various places, including at the end of this 
file.  You are free to use this software however you see fit.

tclTCP+ provides the following:

1)  TCP/IP connections between Tcl applications for exchanging Tcl strings.
2)  Facilities for creating Tcl-based servers spawned from inetd.
3)  Timer event handling from within Tcl-based applications.

See the man page for Tcl-level details.

To use tclTCP+ in your application, add a call to Tcp_Init() in your
program.  For example, to add tclTCP+ to the standard wish program,
add the call to Tcp_Init() after the call to Tk_Init() in tkAppInit.c
- the result should look something like this:

    /*
     * Call the init procedures for included packages.  Each call should
     * look like this:
     *
     * if (Mod_Init(interp) == TCL_ERROR) {
     *     return TCL_ERROR;
     * }
     *
     * where "Mod" is the name of the module.
     */

    if (Tcl_Init(interp) == TCL_ERROR) {
	return TCL_ERROR;
    }
    if (Tk_Init(interp) == TCL_ERROR) {
	return TCL_ERROR;
    }
    if (Tcp_Init(interp) == TCL_ERROR) {
	return TCL_ERROR;
    }

To compile the tclTCP+ files, insert the object files into the list
for the standard Tk or Tcl Makefiles.  For example, this line shows
the changes needed in the tk3.6 Makefile.
