The GNU Scientific Library (GSL) is a collection of routines for
numerical computing. The routines are written from scratch by the GSL
team in ANSI C and present a modern Applications Programming Interface
(API) for C programmers, while allowing wrappers to be written for very
high level languages.

The library covers the following areas:

Complex Numbers Roots of Polynomials Special Functions
Vectors and Matrices Permutations Sorting BLAS Support
Linear Algebra Eigensystems Fast Fourier Transforms
Quadrature Random Numbers Quasi-Random Sequences Random
Distributions Statistics Histograms N-Tuples
Monte Carlo Integration Simulated Annealing Differential
Equations Interpolation Numerical Differentiation Chebyshev
Series Acceleration Approximation Discrete Hankel
Root-Finding Minimization Transforms Least-Squares Fitting
Physical Constants IEEE Floating-Point

hping is a command-line oriented TCP/IP packet assembler/analyzer.
The interface is inspired to the ping(8) unix command, but hping
isn't only able to send ICMP echo requests. It supports TCP, UDP,
ICMP and RAW-IP protocols, has a traceroute mode, the ability to
send files between a covered channel, and many other features.

This package was branched from devel:libraries:c_c++ in order to ... update to 1.0.2

The iODBC Driver Manager is a free implementation of the SAG CLI and
ODBC compliant driver manager which allows developers to write ODBC
compliant applications that can connect to various databases using
appropriate backend drivers.

JSON-C implements a reference counting object model that allows you to
easily construct JSON objects in C, output them as JSON formatted
strings and parse JSON formatted strings back into the C
representation of JSON objects.

Libbraille is a computer shared library which makes it possible to
easily develop for Braille displays. It provides a simple API to
write text on the display, directly draw dots, or get the value of
keys pressed on the Braille keyboard.

c-ares is a C library that performs DNS requests and name resolves
asynchronously. c-ares is a fork of the library named 'ares', written
by Greg Hudson at MIT.

libdiscid is a C library for creating MusicBrainz 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.

The interface of this library is new, but the DiscID algorithm and the
operating system dependent CD-ROM/DVD-ROM access code have been ported
from libmusicbrainz version 2. For more info about the interface read
the [WWW] API documentation.

libfreevec is a free (LGPL) library with hand-optimized replacement
routines for GLIBC, such as memcpy() and strlen(). These routines have
been written specifically to take advantage of the AltiVec unit
(Velocity Engine or VMX) and will only work on processors that include
this unit. This means they will not work on older processors, such as
603, 604, 750 (G3), or the POWER family of CPUs.

GNU SASL is an implementation of the Simple Authentication and
Security Layer framework and a few common SASL mechanisms. SASL is
used by network servers (e.g., IMAP, SMTP) to request authentication
from clients, and in clients to authenticate against servers.

GNU Libidn is an implementation of the Stringprep, Punycode, and IDNA
specifications defined by the IETF Internationalized Domain Names (IDN)
working group. It is used to prepare internationalized strings (such as
domain name labels, usernames, and passwords) in order to increase the
likelihood that string input and string comparison work in ways that
make sense for typical users around the world. The library contains a
generic Stringprep implementation that does Unicode 3.2 NFKC
normalization, mapping and prohibition of characters, and bidirectional
character handling. Profiles for iSCSI, Kerberos 5, Nameprep, SASL, and
XMPP are included. Punycode and ASCII Compatible Encoding (ACE) via
IDNA is supported.

Library needed by programs that use the ltdl interface of GNU libtool.

Libmemcached is a C and C++ client library to the memcached server
(http://danga.com/memcached). It has been designed to be light on
memory usage, thread safe, and provide full access to server side
methods.

GNU libmicrohttpd is a small C library that is supposed to make it easy to run an HTTP server as part of another application. GNU libmicrohttpd is free software and part of the GNU project. Key features that distinguish libmicrohttpd from other projects are:

* C library: fast and small
* API is simple, expressive and fully reentrant
* Implementation is http 1.1 compliant
* HTTP server can listen on multiple ports
* Support for IPv6
* Support for incremental processing of POST data
* Creates binary of only 30k (without TLS/SSL support)
* Three different threading models
* Supported platforms include GNU/Linux, FreeBSD, OpenBSD, NetBSD, OS X, W32, Symbian and z/OS
* Optional support for SSL3 and TLS (requires libgcrypt)

libmicrohttpd was started because the author needed an easy way to add a concurrent HTTP server to other projects. Existing alternatives were either non-free, not reentrant, standalone, of terrible code quality or a combination thereof. Do not use libmicrohttpd if you are looking for a standalone http server, there are many other projects out there that provide that kind of functionality already. However, if you want to be able to serve simple WWW pages from within your C or C++ application, check it out.

mowgli is a development framework for C (like GLib), which provides
high performance and highly flexible algorithms. It can be used as a
suppliment to GLib (to add additional functions (dictionaries,
hashes), or replace some of the slow GLib list manipulation
functions), or stand alone. It also provides a powerful hook system
and convenient logging for your code, as well as a high performance
block allocator

MusicBrainz is the second generation incarnation of the CD Index. This
server is designed to enable audio CD, MP3 and Vorbis players to
download metadata about the music they are playing.

Nettle is a cryptographic library that is designed to fit easily in more or
less any context: In crypto toolkits for object-oriented languages (C++,
Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel space.

librsync implements the "rsync" algorithm, which allows remote
differencing of binary files. librsync computes a delta relative to a
file's checksum, so the two files need not both be present to generate
a delta.

The librtas shared library provides userspace with an interface through
which certain RTAS calls can be made. The library uses either of the
RTAS User Module or the RTAS system call to direct the kernel in making
these calls.

The librtasevent shared library provides users with a set of
definitions and common routines useful in parsing and dumping the
contents of RTAS events.

The libservicelgo package contains a library to create and maintain a
database for storing events related to system service. This database
allows for the logging of serviceable and informational events, and for
the logging of service procedures that have been performed upon the
system.

libssh2 is a library implementing the SSH2 protocol as defined by
Internet Drafts: SECSH-TRANS, SECSH-USERAUTH, SECSH-CONNECTION,
SECSH-ARCH, SECSH-FILEXFER, SECSH-DHGEX, SECSH-NUMBERS, and
SECSH-PUBLICKEY.

LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client.
