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").
