+ * Revision 1.21 2000-02-22 23:11:03 adam
+ * Fixed include statements.
+ *
+ * Revision 1.20 1997/04/30 07:26:08 adam
+ * Added support for shared libaries (if supported by Tcl itself).
+ *
+ * Revision 1.19 1996/08/20 09:27:49 adam
+ * More work on explain.
+ * Renamed tkinit.c to tkmain.c. The tcl shell uses the Tcl 7.5 interface
+ * for socket i/o instead of the handcrafted one (for Tcl 7.3 and Tcl7.4).
