Orc is a library and set of tools for compiling and executing very simple programs that operate on arrays of data. The “language” is a generic assembly language that represents many of the features available in SIMD architectures, including saturated addition and subtraction, and many arithmetic operations.

Allegro is a cross-platform library intended for use in computer games
and other types of multimedia programming.

A wide range of extension packages and add-on modules are also available, which
can be found in the "Library Extensions" section of the Allegro website.

ALURE is a utility library to help manage common tasks with OpenAL
applications. This includes device enumeration and initialization,
file loading, and streaming.

This is a collection of decompression routines for old formats popular
in the Amiga, Atari computers and some other systems from 80's and 90's
as well as some that are currently used which were used in a some
specific way in these old systems.

For simple usage both a simple command line application as well as a
simple API to use the decompressors are provided. The compression
algorithm is automatically detected in most cases, however there are some
corner cases where it is not entirely reliable due to weaknesses in the
old format used.

Argtable3 is an open source ANSI C library that parses GNU-style command-line
options with the getopt library. It simplifies command-line parsing by defining
a declarative-style API that you can use to specify what your command-line syntax
looks like. Argtable3 will automatically generate consistent error handling logic
and textual descriptions of the command line syntax, which are essential but
tedious to implement for a robust CLI program.

Bcg729 is an implementation of both encoder and decoder of the ITU
G.729 Annex A/B speech codec. It supports concurrent channels
encoding/decoding for multi call application such as conferencing.

This package contains the brotli command line utility to compress and
decompress data with the brotli compression algorithm.

Brotli is a generic-purpose lossless compression algorithm that
compresses data using a combination of a modern variant of the LZ77
algorithm, Huffman coding and 2nd order context modeling, with a
compression ratio comparable to the best currently available
general-purpose compression methods. It is similar in speed with
deflate but offers more dense compression.

The specification of the Brotli Compressed Data Format is defined in
RFC 7932.

Capstone is a disassembly framework.
disasm engine for binary analysis and reversing in the security community.

A simple JSON parser library written in ANSI C.

libConfuse is a configuration file parser library. It supports
sections and (lists of) values (strings, integers, floats, booleans
or other sections), as well as single/double-quoted strings,
environment variable expansion, functions and nested include
statements.

cURL is a tool for getting files from HTTP, FTP, FILE, LDAP, LDAPS,
DICT, TELNET and TFTP servers, using any of the supported protocols.
cURL is designed to work without user interaction or any kind of
interactivity. cURL offers many useful capabilities, like proxy
support, user authentication, FTP upload, HTTP post, and file transfer
resume.

This is the MinGW cross-compiled Windows library.
