 DESCRIPTION
      Tcl_AppInit is a procedure that is invoked by the  main  programs  for
      Tcl  applications such as tclsh and wish.  Its purpose is to allow new
      Tcl  applications  to  be  created  without  modifying  existing  main
      programs  such  as  those  for  tclsh  and  wish.   To  create  a  new
      application simply write a new version of Tcl_AppInit to  replace  the
      default  version  provided by Tcl, then link your new Tcl_AppInit with
      the Tcl library, which contains the main program from tclsh  (be  sure
      to  specify  the  switch ``-u _main'' to the linker to force it to use
      the version of main from the Tcl library).

      Tcl_AppInit is invoked after other initialization in main  and  before
      entering the main loop to process commands.  Here are some examples of
      things that Tcl_AppInit might do:

      [1]  Call initialization procedures for various packages used  by  the
           application.   Each initialization procedure adds new commands to
           interp  for  its  package  and  performs  other  package-specific
           initialization.

      [2]  Process command-line arguments, which can be  accessed  from  the
           Tcl variables argv and argv0 in interp.

      [3]  Invoke a startup script to initialize the application.
