- /* 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").
