DESCRIPTION
     Tcl_Init  is a helper procedure that finds and sources the init.tcl script,
     which should exist somewhere on the Tcl library path.

     Tcl_Init is typically called from Tcl_AppInit procedures.

     Tcl_SetPreInitScript registers the pre-initialization  script  and	 returns
     the former (now replaced) script pointer.	A value of NULL may be passed to
     not  register  any	 script.   The	pre-initialization script is executed by
     Tcl_Init before accessing the file system. The purpose is to typically pre-
     pare a custom file system (like an embedded zip-file) to be  activated  be-
     fore the search.

     When used in stub-enabled embedders, the stubs table must be first initial-
     ized  using one of Tcl_InitSubsystems, Tcl_SetPanicProc, Tcl_FindExecutable
     or TclZipfs_AppHook before Tcl_SetPreInitScript may be called.
