DESCRIPTION
     These functions are used to initialize Extended Tcl and applications  based
     on  Extended  Tcl.   This manual page also discusses various issues and ap-
     proaches of integrating TclX into other applications.

   Tclx_Init
     Initializes Extended Tcl, adding the extended command  set  to  the  inter-
     preter.  This is called from Tcl_AppInit.	This function must be called af-
     ter the Tcl_Init function.  In addition to the standard command set, it en-
     ables  use  of  tlib packages libraries and makes the standard TclX library
     available.

     Parameters
       o interp - A pointer to the interpreter to add the commands to.

     Returns:
       TCL_OK if all is ok, TCL_ERROR if an error occurred.

   Tclxcmd_Init
     Add the TclX command set to the interpreter, with the exception of the TclX
     library management commands.  This is  normally  called  by  Tclx_Init  and
     should only be used if you don't want the TclX library handling.

     Parameters
       o interp - A pointer to the interpreter to add the commands to.

     Returns:
       TCL_OK if all is ok, TCL_ERROR if an error occurred.

   TclX_Main
     This  function parses the command line according to the TclX shell specifi-
     cation (Unix shell compatible).  It creates an interpreter  and  calls  the
     specified	function appInitProc to initialize any application specific com-
     mands.  It then either evaluates the command of  script  specified  on  the
     command  line  or enters an interactive command loop.  This procedure never
     returns, it exits the process when it's done.  Using the  TclX  shell  also
     gives you SIGINT handling in interactive shells.

   Tkx_Init
     Initializes  Extended  Tcl Tk environment.  This is called from Tcl_AppInit
     after the Tk_Init function.

     Parameters
       o interp - A pointer to the interpreter to add the commands to.

     Returns:
       TCL_OK if all is ok, TCL_ERROR if an error occurred.

   TkX_Main
     This function parses the command line according to the wish shell	specifi-
     cation.   It  creates  an	interpreter and calls the specified function ap-
     pInitProc to initialize any application specific commands.  It then  either
     evaluates	the command of script specified on the command line or enters an
     interactive command loop.	This  procedure  never	returns,  it  exits  the
     process  when  it's  done.  Using the TclX wish shell gives you SIGINT han-
     dling in interactive shells, otherwise it is identical to standard wish.

   TclX_SetAppInfo
     Store the application information returned by infox.

     Parameters
       o defaultValues - If true, then the values are assigned only if they  are
       not already defined (defaulted).  If false, the values are always set.
       o appName - Application symbolic name.
       o appLongName - Long, natural language application name.
       o appVersion - Version number of the application.
       o  appPatchlevel  -  Patch  level of the application.  If less than zero,
       don't change.

     String pointers are saved without copying, don't release  the  memory.   If
     the arguments are NULL, don't change the values.

DYNAMIC LOADING OF TCLX
     TclX can be dynamically loaded on systems that support shared libraries and
     the  load	command.   This can be done using either the load or the package
     require commands.	If package require is to be used, a pkgIndex,tcl must be
     constructed.  The pkg_mkIndex does not generate a	pkgIndex.tcl  file  that
     works with TclX.  Instead a command similar to

       package ifneeded Tclx 7.5.0 "load $dir/libtclx.so"

     should  be  placed  in the directory containing the TclX shared library.  A
     prototype pkgIndex,tcl file is build by TclX and is installed  in	the  run
     time directory under the name  pkgIndex,proto.  This file can't be used as-
     is,  but  should  be renamed and copied or combined with an existing pkgIn-
     dex,tcl in the directory containing the shared library.

     There is no need to dynamically load libtkx.so, since it only contains sup-
     port for wishx.

INTEGRATING TCLX WITH OTHER EXTENSIONS AND APPLICATIONS
     The main aspects to integrating TclX with into an application is to  decide
     if  the  application  is  based  on  the standard Tcl/Tk shells or the TclX
     shells.  If the standard shells are desired, then all that is necessary  is
     to call Tclx_Init after Tcl_Init and
      Tkx_Init	after  Tk_Init.   This	functionality  may  also  be dynamically
     loaded.

     To get the TclX shell in a Tcl only application, with the tcl command func-
     tionality, call TclX_Main from the main function instead of Tcl_Main.  This
     shell has arguments conforming to other Unix shells and SIGINT signal  han-
     dling when interactive,.

     To get the Tclx shell in a Tk application, with the wishx command function-
     ality, call TkX_Main from the main function instead of Tk_Main.  This shell
     has SIGINT signal handling when interactive,
