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 projects to complete application suites.

GtkGLExt is an OpenGL extension to GTK. It provides the GDK objects
that support OpenGL rendering in GTK and GtkWidget API add-ons, to make
GTK+ widgets OpenGL-capable.

GtkHTML is a lightweight HTML rendering/printing/editing engine. It
was originally based on KHTMLW, part of the KDE project, but is now
being developed independently.

Gtkmm provides a C++ interface to the GTK+ GUI library. gtkmm2 wraps
GTK+ 2. Highlights include typesafe callbacks, widgets extensible via
inheritance, and a comprehensive set of widget classes that can be
freely combined to quickly create complex user interfaces.

GTK+ 3. Highlights include typesafe callbacks, widgets extensible via
inheritance, and a comprehensive set of widget classes that can be
freely combined to quickly create complex user interfaces.

GtkSourceView is a text widget that extends GtkTextView, the standard
GTK+ text widget.

It improves GtkTextView by implementing syntax highlighting and other
features typical of a source editor.

GtkSpell provides MSWord-style and MacOSX-style highlighting of
misspelled words in a GtkTextView widget. Right-clicking a misspelled
word opens a menu of suggested replacements.

Gucharmap is a featureful unicode character map.

GUPnP implements the UPnP specification: resource announcement and
discovery, description, control, event notification, and presentation
(GUPnP includes basic web server functionality through libsoup). GUPnP
does not include helpers for construction or control of specific
standardized resources (e.g. MediaServer); this is left for higher level
libraries utilizing the GUPnP framework.

gupnp-igd is a library to handle UPnP IGD port mapping. It is supposed
to have a very simple API.

VFS functionality for GLib.

HarfBuzz is an OpenType text shaping engine.

This is the default fallback theme used by implementations of the icon
theme specification.

A script for creating a symlink mapping for deprecated icon names to
the new icon naming specification names for desktop icon themes.

iLBC (internet Low Bitrate Codec) is a FREE speech codec suitable for
robust voice communication over IP. The codec is designed for narrow
band speech and results in a payload bit rate of 13.33 kbit/s with an
encoding frame length of 30 ms and 15.20 kbps with an encoding length
of 20 ms. The iLBC codec enables graceful speech quality degradation in
the case of lost frames, which occurs in connection with lost or
delayed IP packets.

Inkscape is a vector illustration program for the GNOME desktop.

Some scripts to support translators working on GNOME and similar
programs. Data available in XML files (.oaf, .desktop, .sheet, and
more) can be extracted into PO files. After translation, the new
information is written back into the XML files.

This package provides the ISO-639 language code list, the ISO-3166
territory code list, ISO-3166-2 subterritory lists, and all their
translations in gettext .po form.

ITS Tool extracts messages from XML files and outputs PO template files, then
merges translations from MO files to create translated XML files. It determines
what to translate and how to chunk it into messages using the W3C
Internationalization Tag Set (ITS).

JSON is a lightweight data-interchange format.It is easy for humans to
read and write. It is easy for machines to parse and generate.

JSON-GLib provides a parser and a generator GObject classes and various
wrappers for the complex data types employed by JSON, such as arrays
and objects.

JSON-GLib uses GLib native data types and the generic value container
GValue for ease of development. It also provides integration with the
GObject classes for direct serialization into, and deserialization from,
JSON data streams.

Libart is a library for high-performance 2D graphics. It is currently
being used as the antialiased rendering engine for GNOME Canvas. It is
also the rendering engine for Gill, the GNOME Illustration application.

libass is a portable subtitle renderer for the ASS/SSA
(Advanced Substation Alpha/Substation Alpha) subtitle
format. It is mostly compatible with VSFilter.
