DESCRIPTION

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

   Tclx_Init
       Initializes  Extended  Tcl,  adding  the extended command set to the interpreter.  This is
       called from Tcl_AppInit.  This function must be called after the  Tcl_Init  function.   In
       addition  to the standard command set, it enables 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  specification  (Unix
       shell compatible).  It creates an interpreter and calls the specified function appInitProc
       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  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  specification.   It
       creates  an  interpreter  and  calls  the specified function appInitProc 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  handling
       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 pkgIndex,tcl in the directory containing the shared library.

       There is no need to dynamically load libtkx.so, since it only contains support 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 functionality, call
       TclX_Main from the main function instead of Tcl_Main.  This shell has arguments conforming
       to other Unix shells and SIGINT signal handling when interactive,.

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