This program, given a source file, produces a document with syntax highlighting. At the moment this package can handle : Java, Javascript, C/C++, Prolog, Perl, Php3, Python, Flex, ChangeLog, Ruby, Lua, Caml, Sml and Log as source languages, and HTML, XHTML and ANSI color escape sequences as output format.
SoX (Sound eXchange) is a sound file format converter SoX can convert between many different digitized sound formats and perform simple sound manipulation functions, including sound effects.
The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion -- it may be used, for example, to resample PCM-encoded audio.
SpamAssassin provides you with a way to reduce if not completely eliminate Unsolicited Commercial Email (SPAM) from your incoming email. It can be invoked by a MDA such as sendmail or postfix, or can be called from a procmail script, .forward file, etc. It uses a genetic-algorithm evolved scoring system to identify messages which look spammy, then adds headers to the message so they can be filtered by the user's mail reading software. This distribution includes the spamd/spamc components which create a server that considerably speeds processing of mail. To enable spamassassin, if you are receiving mail locally, simply add this line to your ~/.procmailrc: INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc To filter spam for all users, add that line to /etc/procmailrc (creating if necessary).
SpamBayes will attempt to classify incoming email messages as 'spam', 'ham' (good, non-spam email) or 'unsure'. This means you can have spam or unsure messages automatically filed away in a different mail folder, where it won't interrupt your email reading. First SpamBayes must be trained by each user to identify spam and ham. Essentially, you show SpamBayes a pile of email that you like (ham) and a pile you don't like (spam). SpamBayes will then analyze the piles for clues as to what makes the spam and ham different. For example; different words, differences in the mailer headers and content style. The system then uses these clues to examine new messages.
Spatialindex provides a general framework for developing spatial indices. Currently it defines generic interfaces, provides simple main memory and disk based storage managers and a robust implementation of an R*-tree, an MVR-tree and a TPR-tree.
Speex is a patent-free compression format designed especially for speech. It is specialized for voice communications at low bit-rates in the 2-45 kbps range. Possible applications include Voice over IP (VoIP), Internet audio streaming, audio books, and archiving of speech data (e.g. voice mail).
