About gtk+
==========

GTK+ is a multi-platform toolkit for creating graphical user
interfaces. Offering a complete set of widgets, GTK+ is suitable for
projects ranging from small one-off tools to complete application
suites.

GTK+ has been designed from the ground up to support a range of
languages, not only C/C++. Using GTK+ from languages such as Perl and
Python (especially in combination with the Glade GUI builder) provides
an effective method of rapid application development.

GTK+ is free software and part of the GNU Project. However, the
licensing terms for GTK+, the GNU LGPL, allow it to be used by all
developers, including those developing proprietary software, without
any license fees or royalties.
