/* vi:set ts=8 sts=4 sw=4:
*
* VIM - Vi IMproved by Bram Moolenaar
*
* Do ":help uganda" in Vim to read copying and usage conditions.
* Do ":help credits" in Vim to see a list of people who contributed.
* See README.txt for an overview of the Vim source code.
*/
/*
* Porting to GTK+ was done by:
*
* (C) 1998,1999,2000 by Marcin Dalecki <martin@dalecki.de>
*
* With GREAT support and continuous encouragements by Andy Kahn and of
* course Bram Moolenaar!
*
* Support for GTK+ 2 was added by:
*
* (C) 2002,2003 Jason Hildebrand <jason@peaceworks.ca>
* Daniel Elstner <daniel.elstner@gmx.net>
