     NAME
          Tcl_AppInit - Perform application-specific initialization

     SYNOPSIS
          #include <tcl.h>

          Tcl_AppInit(interp)

     ARGUMENTS
          Tcl_Interp   *interp   (in)      Interpreter     for     the
                                           application.

     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.
