formatted CSV files.

v4l-utils is a collection of various video4linux (V4L) and DVB utilities.

libv4l is a collection of libraries which adds a thin abstraction layer on
top of video4linux2 devices. The purpose of this (thin) layer is to make it
easy for application writers to support a wide variety of devices without
having to write separate code for different devices in the same class. libv4l
consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2.

Vc is a free software library to ease explicit vectorization of C++ code. It
has an intuitive API and provides portability between different compilers and
compiler versions as well as portability between different vector instruction
sets.

Xplanet can display the earth or other planets in the background of
your display, similar to xearth or xglobe. Additionally, it can run in
interactive mode allowing you to rotate or zoom the planet. Also, with
an included script, it is very easy to combine map files with current
satellite cloud images.

QElectroTech is an application to design electric diagrams. It uses XML
files for elements and diagrams, and includes both a diagram editor and an
element editor.

QMC2 is a Qt based multi-platform GUI front end MAME.

QMC2 – M.A.M.E. Catalog / Launcher II is the successor of one of the first UNIX
M.A.M.E. GUI front ends available on this planet called QMamecat (derived from
MAMECAT, which was text-only).

Program for playing and analysing backgammon positions, games and matches. It's based on a neural network. It currently plays at about the level of a championship flight tournament player. Depending on its parameters and its luck in recent games, it rates from around 1900 to 2000 on FIBS, the First Internet Backgammon Server -- at its strongest, it ranks in the top 5 of over 6000 rated players there and is gradually improving.

An optimized implementation of the JPEG-LS standard for lossless and
near-lossless image compression. JPEG-LS is a low-complexity standard that
matches JPEG 2000 compression ratios. In terms of speed, CharLS outperforms
open source and commercial JPEG LS implementations.

libpgf is a library for working with PGF (Progresive Graphics File) images.

OpenColorIO (OCIO) is a complete color management solution geared towards
motion picture production with an emphasis on visual effects and computer
animation. OCIO provides a straightforward and consistent user experience
across all supporting applications while allowing for sophisticated back-end
configuration options suitable for high-end production usage. OCIO is
compatible with the Academy Color Encoding Specification (ACES) and is
LUT-format agnostic, supporting many popular formats.

OpenJPEG library is an open-source JPEG 2000 codec written in C. It has been
developed in order to promote the use of JPEG 2000, the new still-image
compression standard from the Joint Photographic Experts Group (JPEG).

Utilities written to make jigdo files easier to work with.

Translations for Calligra Suite applications and manuals.

CFITSIO is a library of C and Fortran subroutines for reading and writing data
files in FITS (Flexible Image Transport System) data format. CFITSIO provides
simple high-level routines for reading and writing FITS files that insulate the
programmer from the internal complexities of the FITS format. CFITSIO also
provides many advanced features for manipulating and filtering the information
in FITS files.

An optimized implementation of the JPEG-LS standard for lossless and
near-lossless image compression. JPEG-LS is a low-complexity standard that
matches JPEG 2000 compression ratios. In terms of speed, CharLS outperforms
open source and commercial JPEG LS implementations.

DCMTK is a collection of libraries and applications implementing large
parts the DICOM standard.

dd_rhelp is a bash script that handles dd_rescue. dd_rescue roughly acts as the
dd linux command with the caracteristic to NOT stop when it falls on
read/write.

GL2PS is a C library providing high quality vector output for any OpenGL
application. The main difference between GL2PS and other similar libraries is
the use of sorting algorithms capable of handling intersecting and stretched
polygons, as well as non manifold objects. GL2PS provides advanced smooth
shading and text rendering, culling of invisible primitives, mixed
vector/bitmap output, and much more...

GL2PS can currently create PostScript (PS), Encapsulated PostScript (EPS),
Portable Document Format (PDF) and Scalable Vector Graphics (SVG) files, as
well as LATEX files for the text fragments. GL2PS also provides limited,
experimental support for Portable LaTeX Graphics (PGF). Adding new vector
output formats should be relatively easy; you can also use the excellent
pstoedit program to transform the PostScript files generated by GL2PS into many
other vector formats such as xfig, cgm, wmf, etc.

INDI is an Instrument Neutral Distributed Interface control protocol
for astronomical devices, which provides a framework that decouples low
level hardware drivers from high level front end clients. Clients that
use the device drivers are completely unaware of the device
capabilities and communicate with the device drivers and build a
completely dynamic GUI based on the services provided by the device.

libkvkontakte is a KDE C++ library for asynchronous interaction with
vkontakte.ru social network via its open API.

This library provides widgets and classes to interface a Qt-based applications
with OpenGTL.

The Graphics Transformation Languages is a set of library for using and
integrating transformation algorithms (such as filter or color conversion) in
graphics applications.

The goal is to provide the tools, languages and libraries to create generic
transformation for graphics. Those transformations could then be used by
different programs.
