 * 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>
 *
 * Best supporting actor (He helped somewhat, aesthetically speaking):
 * Maxime Romano <verbophobe@hotmail.com>
