   1 /* appinit.c -- Tcl and Tk application initialization.
   2
   3    The function Tcl_AppInit() below initializes various Tcl packages.
   4    It is called for each Tcl interpreter created by _tkinter.create().
   5    It needs to be compiled with -DWITH_<package> flags for each package
   6    that you are statically linking with.  You may have to add sections
   7    for packages not yet listed below.
   8
   9    Note that those packages for which Tcl_StaticPackage() is called with
  10    a NULL first argument are known as "static loadable" packages to
  11    Tcl but not actually initialized.  To use these, you have to load
  12    it explicitly, e.g. tkapp.eval("load {} Blt").
