* interpreters. It looks in several different directories
* for a script "tk.tcl" that is compatible with this version
* of Tk. The tk.tcl script does all of the real work of
* initialization.
* When called from a safe interpreter, it does not use file exists.
* we don't use pwd either because of safe interpreters.
*
* We leave the door open to the application by using an existing
* tkInit proc which if it exists is responsible for finding and sourcing
* tk.tcl themselves. With that, an application that wish to ignore
* the env(TK_LIBRARY) or have special initialization need can do it.
