/* appinit.c -- Tcl and Tk application initialization.

   The function Tcl_AppInit() below initializes various Tcl packages.
   It is called for each Tcl interpreter created by _tkinter.create().
   It needs to be compiled with -DWITH_<package> flags for each package
   that you are statically linking with.  You may have to add sections
   for packages not yet listed below.

   Note that those packages for which Tcl_StaticPackage() is called with
   a NULL first argument are known as "static loadable" packages to
   Tcl but not actually initialized.  To use these, you have to load
   it explicitly, e.g. tkapp.eval("load {} Blt").
