Merkaartor is a small editor for OpenStreetMap available under the GNU General Public License and developed using the Qt toolkit.

It has some unique features like anti-aliased displaying, transparent display of map features like roads and true curved roads.

ZBar is an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 and QR Code.

Lossless data compression codec with LZMA-like ratios but optimized for decompression speed, C/C++.

LZMA SDK provides the documentation, samples, header files, libraries,
and tools you need to develop applications that use LZMA compression.

LZMA is default and general compression method of 7z format
in 7-Zip compression program (www.7-zip.org). LZMA provides high
compression ratio and very fast decompression.

LZMA is an improved version of famous LZ77 compression algorithm.
It was improved in way of maximum increasing of compression ratio,
keeping high decompression speed and low memory requirements for
decompressing.

A command line utility to pack and unpack zip archives using
multiple threads.

Supports
both zipping and unzipping
multithreading
uncompressed (i.e. stored) files
deflate and lzma compression and decompression
ZIP64 extensions (i.e. >4 GB files)
unix file attributes

Does not support
modifying existing archives
encryption (zip encryption is broken, use GPG instead)
ancient compression methods
archives split to multiple files

The Unarchiver is originally a Mac OS X application. This package
contains a command-line variant of it. Unarchiver handles ZIP, ZIPX,
RAR, 7z, tar, gzip, bzip2, lzma, xz, CAB, MSI, NSIS, some
self-extracting EXEs, cpio, and further obscure and old formats, as
well as disc images in ISO, BIN, MDF, NRG, CDI. It supports filenames
in foreign character sets.

LZX uses a compact way of encoding large match offsets. The Amiga implementation includes file merging, where data are grouped into large blocks, instead of being individually compressed.

This is based on the UnLZX port by David Tritscher

GNU Cobol (formerly OpenCOBOL) is a free COBOL compiler. cobc translates COBOL to executable using intermediate C sources, providing full access to nearly all C libraries.

Pony is an open-source, object-oriented, actor-model, capabilities-secure, high performance
programming language.

Lazarus is a free and open source Rapid Application Development
tool for the FreePascal compiler using the Lazarus component
library - LCL. The LCL is included in this package.

This module returns a hash containing basic information about a Musepack
file, as well as tag information contained in the Musepack file's APE
tags.

CDDB protocol (cddbp) servers provide compact disc information for programs
that need it. This allows such programs to display disc and track titles
automatically, and it provides extended information like liner notes and
lyrics.

This module provides a high-level Perl interface to cddbp servers. With it,
a Perl program can identify and possibly gather details about a CD based on
its "table of contents" (the disc's track times and offsets).

Disc details have been useful for generating CD catalogs, naming mp3 files,
printing CD liners, or even just playing discs in an automated jukebox.

Despite the module's name, it connects to FreeDB servers by default. This
began at version 1.04, when cddb.com changed its licensing model to support
end-user applications, not third-party libraries. Connections to cddb.com
may still work, and patches are welcome to maintain that functionality, but
it's no longer officially supported.

This module allows a Perl developer to embed an arbitrary widget in a System
Tray like the Gnome notification area.

Net::DBus::GLib provides an extension to the Net::DBus module allowing integration with the GLib mainloop. To integrate with the main loop, simply get a connection to the bus via the methods in Net::DBus::GLib rather than the usual Net::DBus module. That's it - every other API remains the same.

This package provides some functions to control UPnP devices.

Currently, the package provides only functions for the control point. To control
UPnP devices, see Net::UPnP::ControlPoint.

As a sample of the control point, the package provides Net::UPnP::AV::MediaServer
to control the devices such as DLNA media servers. As the example, please
dms2vodcast.pl that converts from the MPEG2 movies to the MPEG4 one and outputs
the RSS file for Vodcasting.

GuessIt is a python library that extracts as much information as
possible from a video file.

It has a very powerful filename matcher that allows to guess a lot of
metadata from a video using its filename only. This matcher works with
both movies and tv shows episodes.

This is a little HTTP/1.1 library written from scratch in Python,
heavily inspired by hyper-h2

Kivy is an open source software library for rapid development of applications that make use of innovative user interfaces, such as multi-touch apps.

The mygpoclient library allows developers to utilize a Pythonic interface to
the my.gpodder.org web services.

pick is a small python library to help you create curses based interactive selection list in the terminal.

Python interface for eSpeak NG, a speech synthesis library.

pymad is a Python module that allows Python programs to use the MPEG Audio
Decoder library. pymad provides a high-level API, similar to the pyogg module,
allowing to read PCM data from MPEG audio streams.

pysrt is a Python library used to edit or create SubRip files.

A ctypes-based python interface to the mpv media player.
It gives more or less full control of all features of the player,
just like the lua interface does.
