+ * Windows GUI.
+ *
+ * GUI support for Microsoft Windows, aka Win32.  Also for Win64.
+ *
+ * George V. Reilly <george@reilly.org> wrote the original Win32 GUI.
+ * Robert Webb reworked it to use the existing GUI stuff and added menu,
+ * scrollbars, etc.
+ *
+ * Note: Clipboard stuff, for cutting and pasting text to other windows, is in
+ * winclip.c.	(It can also be done from the terminal version).
+ *
+ * TODO: Some of the function signatures ought to be updated for Win64;
+ * e.g., replace LONG with LONG_PTR, etc.
