/* 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").
