A simple implementation of the RC4 algorithm, developed by RSA
Security, Inc. Here is the description from RSA's website:
RC4 is a stream cipher designed by Rivest for RSA Data Security
(now RSA Security). It is a variable key-size stream cipher with
byte-oriented operations. The algorithm is based on the use of a
random permutation. Analysis shows that the period of the cipher
is overwhelmingly likely to be greater than 10100. Eight to sixteen
machine operations are required per output byte, and the cipher can
be expected to run very quickly in software. Independent analysts
have scrutinized the algorithm and it is considered secure.
Based substantially on the "RC4 in 3 lines of perl" found at

This keyboard is designed to enable simple input in all European
languages which use Latin-script, and in most Latin-script languages
from the rest of the world.
The keyboard is written in KMN Keyboard Language by the KMN language
developer, Tavultesoft (http://www.tavultesoft.com). The keyboard
uses punctuation and letter keys in sequence to access diacritic and
other letters.
This port installs the keyboard so that it can be used through SCIM or
IBus KMFL IMEngine (textproc/scim-kmfl-imengine, textproc/ibus-kmfl).
It currently covers 120 languages including: Afrikaans, Albanian,
Balearic, Basque, Breton, Catalan, Croatian, Czech, Danish, Dutch,
Esperanto, Estonian, Faroese, Finnish, French, Gaelic, Galician,
German, Hungarian, Icelandic, Inuktitut, Italian, Kashubian, Ladin,
Latvian, Lithuanian, Maltese, Norwegian, Nynorsk, Polish, Portugese,
Romansch, Saami, Serbian, Slovak, Slovenian, Sorbian, Spanish,
Swedish, Tagalog, Turkish, Valencian, Vlaams, Walloon, Welsh and Zulu.
The keyboard is distributed under the terms of 3-clause BSD-licence.
CQL::Parser provides a mechanism to parse Common Query Language (CQL)
statements. The best description of CQL comes from the CQL homepage at the
Library of Congress http://www.loc.gov/z3950/agency/zing/cql/
CQL is a formal language for representing queries to information retrieval
systems such as web indexes, bibliographic catalogs and museum collection
information. The CQL design objective is that queries be human readable
and human writable, and that the language be intuitive while maintaining
the expressiveness of more complex languages.
A CQL statement can be as simple as a single keyword, or as complicated as
a set of compoenents indicating search indexes, relations, relational
modifiers, proximity clauses and boolean logic. CQL::Parser will parse CQL
statements and return the root node for a tree of nodes which describes
the CQL statement. This data structure can then be used by a client
application to analyze the statement, and possibly turn it into a query
for a local repository.
Chess::PGN::Parse offers a range of methods to read and manipulate
Portable Game Notation files. PGN files contain chess games produced by
chess programs following a standard format
(http://www.schachprobleme.de/chessml/faq/pgn/). It is among the preferred
means of chess games distribution. Being a public, well established
standard, PGN is understood by many chess archive programs. Parsing simple
PGN files is not difficult. However, dealing with some of the intricacies
of the Standard is less than trivial. This module offers a clean handle
toward reading and parsing complex PGN files.
A PGN file has several tags, which are key/values pairs at the header of
each game, in the format [key "value"]
After the header, the game follows. A string of numbered chess moves,
optionally interrupted by braced comments and recursive parenthesized
variants and comments. While dealing with simple braced comments is
straightforward, parsing nested comments can give you more than a
headache.
Perl bindings to the 2.x series of the Gtk+ graphical user interface library.
This module allows you to write graphical user interfaces in a perlish and
object-oriented way, freeing you from the casting and memory management in C,
yet remaining very close in spirit to original API. Find out more about Gtk+
at http://www.gtk.org.
The GTK+ Reference Manual is also a handy companion when writing Gtk
programs in any language. http://developer.gnome.org/doc/API/2.0/gtk/
The perl bindings follow the C API very closely, and the C reference
documentation should be considered the canonical source.

This LaTeX package extends the capabilities of TeX/LaTeX to generate
the arabic writing from an ASCII transliteration for texts in several
languages using the arabic script.
Several other common encodings are also supported.
Nightfall is an astronomy application for fun, education, and science. It
can produce animated views of eclipsing binary stars, calculate synthetic
lightcurves and radial velocity curves, and eventually determine the
best-fit model for a given set of observational data of an eclipsing binary
star system. It is, however, not able to fry your breakfast egg on your
harddisk. ;-)
This is a WindowMaker dockapp that displays a graphical representation of
the phase of the moon, plus additional astronomical data such as
rise/set times, orbital data, orbital elements, etc (if you click on the
image multiple times).
Probably most of the data is not that useful, but what the heck :)
Audio file utility programs and a library of routines for audio files.
Audio File Utility Programs:
InfoAudio - display information about an audio file.
CompAudio - compare audio files, producing statistics and signal-to-noise
ratio figures.
CopyAudio - copy audio files. This program combines samples from input audio
files (an arbitrary linear combination) and writes them to the
output file in a user selectable format. One application is to
provide format conversion for an audio file; another is to
combine samples from multi-channel files.
ResampAudio - resample data from an audio file. This process involves
interpolating between the samples in the original file to create
a new sequence of samples with a new spacing (sampling rate).
and FiltAudio, GenNoise, GenTone, LPanal, LPsyn
The following file formats are supported for reading.
- Headerless, AU, WAVE, AIFF/AIFF-C, NIST SPHERE, IRCAM,
INRS-Telecom, ESPS, Comdisco SPW, Text audio
The following file formats are supported for writing.
- Headerless, AU, WAVE, AIFF-C
The idea of IMB is to provide a concise set of elementary MPI
benchmark kernels. With one executable, all of the supported
benchmarks, or a subset specified by the command line, can be run.
The rules, such as time measurement (including a repetitive call
of the kernels for better clock synchronization), message lengths,
selection of communicators to run a particular benchmark (inside
the group of all started processes) are program parameters.
