Lua is a programming language originally designed for extending applications,
but also frequently used as a general-purpose, stand-alone language. Lua
combines simple procedural syntax (similar to Pascal) with powerful data
description constructs based on associative arrays and extensible semantics.
Lua is dynamically typed, interpreted from bytecodes, and has automatic memory
management with garbage collection, making it ideal for configuration,
scripting, and rapid prototyping.
A fundamental concept in the design of Lua is to provide meta-mechanisms for
implementing features, instead of providing a host of features directly in
the language. For example, although Lua is not a pure object-oriented
language, it does provide meta-mechanisms for implementing classes and
inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the
language small, while allowing the semantics to be extended in unconventional
ways. Extensible semantics is a distinguishing feature of Lua.
Lua is implemented as a small library of C functions, written in ANSI C, and
compiles unmodified in all known platforms. The implementation goals are
simplicity, efficiency, portability, and low embedding cost.

This is the port for all stuff that comes in the contrib subtree of
the postgresql distribution. This subtree contains porting tools,
analysis utilities, and plug-in features that are not part of the core
PostgreSQL system, mainly because they address a limited audience or
are too experimental to be part of the main source tree. This does
not preclude their usefulness.
Each subdirectory contains a README file with information about the
module. Some directories supply new user-defined functions, operators,
or types. After you have installed the files you need to register the
new entities in the database system by running the commands in the
supplied .sql file. For example,
$ psql -d dbname -f module.sql
The .sql files are installed into /usr/local/share/postgresql/contrib
For more information, please see
/usr/local/share/doc/postgresql/contrib/README*
This software is part of the standard PostgreSQL distribution.

Botan is a crypto library written in C++. It provides a variety of
cryptographic algorithms, including common ones such as AES, MD5, SHA,
HMAC, RSA, Diffie-Hellman, DSA, and ECDSA, as well as many others that
are more obscure or specialized. It also offers X.509v3 certificates
and CRLs, and PKCS #10 certificate requests. A message processing
system that uses a filter/pipeline metaphor allows for many common
cryptographic tasks to be completed with just a few lines of code.
Assembly optimizations for common CPUs, including x86, x86-64, and
PowerPC, offers further speedups for critical tasks such as SHA-1
hashing and multiple precision integer operations.
Botan is licensed under the same permissive terms as FreeBSD itself.
Libxslt is the XSLT C library developed for the GNOME project. XSLT itself is
a an XML language to define transformation for XML. Libxslt is based on
libxml2, the XML C library developed for the GNOME project. It also implements
most of the EXSLT set of processor-portable extensions functions and some of
Saxon's evaluate and expressions extensions.
People can either embed the library in their application or use xsltproc the
command line processing tool.
