Double-conversion provides binary-decimal and decimal-binary routines
for IEEE double-precision floating point numbers. The library
consists of conversion routines that have been extracted from the V8
JavaScript engine.

libdiscid is a C library for creating MusicBrainz and freedb DiscIDs
from audio CDs.
It reads a CD's table of contents (TOC) and generates an identifier
which can be used to lookup the CD at MusicBrainz.
Additionally, it provides a submission URL for adding the DiscID to the
database and gathers ISRCs and the MCN from disc.

MAD is a MPEG audio decoder. It currently supports MPEG-1 and the
MPEG-2 extension to Lower Sampling Frequencies, as well as the
so-called MPEG 2.5 format. All three audio layers (Layer I, Layer II,
and Layer III a.k.a. MP3) are implemented.

MAD supports 24-bit PCM output. MAD computes using 100%% fixed-point
(integer) computation, so you can run it without a floating point
unit.

libopenmpt is a C++ and C library to decode tracker music files
(modules) into a PCM audio stream. It is based on the player code of
the OpenMPT project, a descendant of the original ModPlug Tracker.

libpcap is a library used by packet sniffer programs. It provides an
interface for them to capture and analyze packets from network devices.
This package is only needed if you plan to compile or write such a
program yourself.

LZ4 is a lossless data compression algorithm that is focused on
compression and decompression speed. It belongs to the LZ77
(Lempel–Ziv) family of byte-oriented compression schemes. It is a
LZP2 fork and provides better compression ratio for text files.

This subpackage provides a GPL command-line utility to make use of
the LZ4 algorithm.

The mpg123 distribution contains an MPEG 1.0/2.0/2.5 audio player/decoder for
layers 1, 2 and 3 (most commonly MPEG 1.0 Layer 3 aka MP3), as well as re-usable decoding
and output libraries.

The Opus codec is designed for interactive speech and audio transmission over
the Internet. It is designed by the IETF Codec Working Group and incorporates
technology from Skype's SILK codec and Xiph.Org's CELT codec.

This is a simple library to load images of various formats as SDL
surfaces. This library supports the BMP, PPM, PCX, GIF, JPEG, PNG,
TIFF and WEBP formats.

This is a networking library for use with SDL.

This is a sample library that allows you to use TrueType fonts in your
SDL applications.

Speex is a patent free audio codec designed especially for voice
(unlike Vorbis which targets general audio) signals and providing good
narrowband and wideband quality. This project aims to be complementary
to the Vorbis codec.

A YAML parser and emitter in C++ matching the YAML 1.2 spec.

Zstd, short for Zstandard, is a lossless compression algorithm. Speed
vs. compression trade-off is configurable in small increments.
Decompression speed is preserved and remains roughly the same at all
settings, a property shared by most LZ compression algorithms, such
as zlib or lzma.

At roughly the same ratio, zstd (v1.4.0) achieves ~870%% faster
compression than gzip. For roughly the same time, zstd achives a
~12%% better ratio than gzip. LZMA outperforms zstd by ~10%% faster
compression for same ratio, or ~1–4%% size reduction for same time.

QToolButton with color popup menu with lets you select a color. The popup
featues a color dialog button which can be used to add custom colors to the
popup menu.

Ksnip is a Qt based cross-platform screenshot tool that provides many
annotation features for your screenshots.

A handy alarm clock Program written in QT.
Features:
* Up to 15 Customization alarms
* Can wake up using the default sound, or any of audio / video
file of your choosing.
* Custom Date alarms
