libssh2 is a library implementing the SSH2 protocol as defined by
Internet Drafts: SECSH-TRANS(22), SECSH-USERAUTH(25),
SECSH-CONNECTION(23), SECSH-ARCH(20), SECSH-FILEXFER(06)*,
SECSH-DHGEX(04), and SECSH-NUMBERS(10).

This is the ASN.1 library used in GNUTLS. More up to date information
can be found at http://www.gnu.org/software/gnutls and

Theora is Xiph.Org's first publicly released video codec, intended
for use within the Ogg's project's Ogg multimedia streaming system.
Theora is derived directly from On2's VP3 codec.

Vorbis is a fully open, nonproprietary, patent-and-royalty-free, and
general-purpose compressed audio format for audio and music at fixed
and variable bit rates from 16 to 128 kbps/channel.

The native bitstream format of Vorbis is libogg (Ogg). Alternatively,
libmatroska (matroska) can also be used.

This library interprets metafile images and can convert them to
standard formats such as PNG, JPEG, PS, EPS, and more.

Library that handles Word Perfect documents.

libwpg is a library for reading and converting WPG images

libwps is a library (for use by word procesors, for example) for
importing the Microsoft Works word processor file format.

Libxml2 is the XML C parser and toolkit developed for the Gnome project.

This C library allows to transform XML files into other XML files
(or HTML, text, ...) using the standard XSLT stylesheet transformation
mechanism. To use it you need to have a version of libxml2 >= 2.6.27
installed. The xsltproc command is a command line interface to the XSLT engine

TNEF Stream Parser Library, used by "ytnef" to decode TNEF (winmail.dat)
streams generated by Microsoft Outlook.

The Link Grammar Parser is a syntactic parser of English, based on link
grammar, an original theory of English syntax. Given a sentence, the
system assigns to it a syntactic structure, which consists of a set of
labeled links connecting pairs of words. The parser also produces a
"constituent" (Penn tree-bank style phrase tree) representation of a
sentence (showing noun phrases, verb phrases, etc.).

Mixed Integer Linear Programming (MILP) solver library lpsolve solves
pure linear, (mixed) integer/binary, semi-continuous and special
ordered sets (SOS) models.

NSPR provides platform independence for non-GUI operating system
facilities. These facilities include threads, thread synchronization,
normal file and network I/O, interval timing and calendar time, basic
memory management (malloc and free) and shared library linking (runtime
libraries).

Network Security Services (NSS) is a set of libraries designed to
support cross-platform development of security-enabled client and
server applications. Applications built with NSS can support SSL v2
and v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME, X.509
v3 certificates, and other security standards.

MPC is a C library for the arithmetic of complex numbers with
arbitrarily high precision and correct rounding of the result. It is
built upon and follows the same principles as MPFR.

The MPFR library is a C library for multiple-precision floating-point
computations with exact rounding (also called correct rounding). It is
based on the GMP multiple-precision library.

The main goal of MPFR is to provide a library for multiple-precision
floating-point computation which is both efficient and has a
well-defined semantics. It copies the good ideas from the ANSI/IEEE-754
standard for double-precision floating-point arithmetic (53-bit
mantissa).

The OpenSSL Project is a collaborative effort to develop a robust,
commercial-grade, full-featured, and open source toolkit implementing
the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS
v1) protocols with full-strength cryptography. The project is managed
by a worldwide community of volunteers that use the Internet to
communicate, plan, and develop the OpenSSL toolkit and its related
documentation.

Derivation and License

OpenSSL is based on the excellent SSLeay library developed by Eric A.
Young and Tim J. Hudson. The OpenSSL toolkit is licensed under an
Apache-style license, which basically means that you are free to get it
and to use it for commercial and noncommercial purposes.

MinGW Windows ORBit2 library.

Pango is a library for laying out and rendering of text, with an emphasis on internationalization. It can be used
anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+
widget toolkit. The integration of Pango with Cairo provides a complete solution with high quality text handling and
graphics rendering.

pangomm provides a C++ interface to the Pango library. Highlights
include typesafe callbacks, widgets extensible via inheritance and a
comprehensive set of widget classes that can be freely combined to
quickly create complex user interfaces.

PDCurses is a public domain curses library for DOS, OS/2, Win32, X11
and SDL, implementing most of the functions available in X/Open and
System V R4 curses. It supports many compilers for these
platforms. The X11 port lets you recompile existing text-mode curses
programs to produce native X11 applications.

Note that ncurses is not available for MinGW / Windows. Applications
which need curses functionality can use this package, provided they
don't use any of the extensions specific to ncurses.

Pidgin allows you to talk to anyone using a variety of messaging
protocols including AIM, MSN, Yahoo!, Jabber, Bonjour, Gadu-Gadu, ICQ,
IRC, Novell Groupwise, QQ, Lotus Sametime, SILC, Simple and Zephyr.
These protocols are implemented using a modular, easy to use design. To
use a protocol, just add an account using the account editor.

Pidgin supports many common features of other clients, as well as many
unique features, such as Perl scripting, TCL scripting and C plugins.

Pidgin is not affiliated with or endorsed by America Online, Inc.,
Microsoft Corporation, Yahoo! Inc., or ICQ Inc.

This is a pidgin plugin which implements Off-the-Record (OTR)
Messaging. OTR allows you to have private conversations over IM
by providing:

- Encryption

- No one else can read your instant messages.

- Authentication

- You are assured the correspondent is who you think it is.

- Deniability

- The messages you send do _not_ have digital signatures that are
checkable by a third party. Anyone can forge messages after a
conversation to make them look like they came from you. However,
_during_ a conversation, your correspondent is assured the
messages he sees are authentic and unmodified.

- Perfect forward secrecy

- If you lose control of your private keys, no previous conversation is
compromised.
