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