Passage: GNOME was started on August 15 1997 by Miguel de Icaza and Federico Mena as a free software project to develop a desktop environment and applications for it. It was founded in part because K Desktop Environment, which was growing in popularity, relied on the Qt widget toolkit which used a proprietary software license until version 2.0 (June 1999). In place of Qt, the GTK toolkit was chosen as the base of GNOME. GTK uses the GNU Lesser General Public License (LGPL), a free software license that allows software linking to it to use a much wider set of licenses, including proprietary software licenses. GNOME itself is licensed under the LGPL for its libraries, and the GNU General Public License (GPL) for its applications.The name "GNOME" was initially an acronym of GNU Network Object Model Environment, referring to the original intention of creating a distributed object framework similar to Microsoft's OLE, but the acronym was eventually dropped because it no longer reflected the vision of the GNOME project.The California startup Eazel developed the Nautilus file manager from 1999 to 2001. De Icaza and Nat Friedman founded Helix Code (later Ximian) in 1999 in Massachusetts; this company developed GNOME's infrastructure and applications, and in 2003 was purchased by Novell.

Question: What was Helix Code later called?
Ximian
