This library allows you to load Glade interface files in a program at
runtime. It does not require that you use Glade, but Glade is the
easiest way to create the interface files. For an idea of how to use
the library, see the documentation, especially
/usr/share/doc/packages/libglade/test-libgladee.c and the glade-xml.h
include, which is in the libglade package.

This package provides a C++ interface for libglade. It is a subpackage
of the gnomemm project. The interface provides a convenient interface
for C++ programmers to use libglade with flexible object-oriented
framework.

your choice. Many GNOME users like Sawfish, Enlightenment, or IceWM as
a window manager for GNOME (see those packages).

The GNOME Keyring is a program that keep password and other secrets
for users. The libgnome-keyring library is used by applications to
integrate with the GNOME Keyring system.

Libgnomecanvas is a graphical add-on for the GNOME User Interface
libraries.

A gobject (GLib) wrapper for IPP printer management, which is used by
CUPS. Mainly used by the GNOME printing system.

GNOME keyboard library, utility and applet.

This package contains the GNOME 2.x printing library, which provides a
simple and clean API for GNOME programs that have to print documents.

This library contains all user-interface related functions to the GNOME
printing subsystem.

Libgnomesu is a library for providing superuser privileges to GNOME
applications. It supports sudo, consolehelper, PAM, and su.

This library contains all the user interface-related functions for
GNOME-based software. You need the libgnomeui-devel package if you want
to develop GNOME 2.x Desktop software.

A library for reading and writing structured files (MS OLE and Zip, for
example).

A library that fetches information about the running system, such as
CPU and memory usage and active processes.

On Linux systems, this information is taken directly from the /proc
file system. On other systems, a server is used to read information
from /dev/kmem.

This is a library to download weather information from online sources.

LibIDL is a small library for creating parse trees of CORBA
v2.2-compliant Interface Definition Language (IDL) files. IDL is a
specification for defining interfaces that can be used between
different CORBA implementations.

libimobiledevice is a software library that talks the protocols to support
iPhone, iPod Touch and iPad devices. Unlike other projects, it does not depend

libiptcdata is a library for parsing, editing, and saving IPTC data.

libiptcdata is a library for manipulating the International Press
Telecommunications Council (IPTC) metadata stored within multimedia
files such as images. This metadata can include captions and keywords,
often used by popular photo management applications. The library
provides routines for parsing, viewing, modifying, and saving this
metadata. The libiptcdata package also includes a command line utility,
iptc, for editing IPTC data in JPEG files. The library implements the
IPTC Information Interchange Model according to its specification.

Kate is a codec for karaoke and text encapsulation for Ogg. Most of the
time, this would be multiplexed with audio/video to carry subtitles,
song lyrics (with or without karaoke data), etc, but doesn't have to be.
A possible use of a lone Kate stream would be an e-book. Moreover, the
motion feature gives Kate a powerful means to describe arbitrary curves,
so hand drawing of shapes can be achieved.

This was originally meant for karaoke use, but can be used for any
purpose. Motions can be attached to various semantics, like position,
color, etc, so scrolling or fading text can be defined.
