Planet is a flexible feed aggregator, this means that it downloads feeds
and aggregates their content together into a single combined feed with
the latest news first.
It uses Mark Pilgrim's Ultra-liberal feed parser so can read from RDF, RSS
and Atom feeds and Tomas Styblo's template library to output static files
in unlimited formats based on a series of templates.
Planet was written for the Planet Debian and Planet GNOME websites by
Scott James Remnant <scott@netsplit.com> and
Jeff Waugh <jdub@perkypants.org>. It was originally based on 'spycyroll'.

URL Link is a small extension that allows you to select a non-URL in a
mail/news message or web-page, and open it in a browser window.
For emails, it reconnects links in emails which have been broken across
several lines, and also replaces spaces with the URL character code %20
so that you may follow emailed network 'file:' links (which it auto-
detects from Windows X: or servdir references).
For web pages, it also allows you to select textual links/URLs in web
pages or edit boxes, and follow them as if they were real links. It
will always let you follow links and also analyses mailto: links.
Ever wish you add information to your photos like a caption, the place
you took it, the date, and perhaps even keywords and categories? You
already can. The International Press Telecommunications Council (IPTC)
defines a format for exchanging meta-information in news content, and
that includes photographs. You can embed all kinds of information in
your images. The trick is putting it to use.
That's where this IPTCInfo Perl module comes into play. You can embed
information using many programs, including Adobe Photoshop, and
IPTCInfo will let your web server -- and other automated server
programs -- pull it back out. You can use the information directly in
Perl programs, export it to XML, or even export SQL statements ready
to be fed into a database.
Paraphrasing the website:
Mailman is a mailing list manager (MLM); that is, software to help manage
email discussion lists, much like Majordomo, LISTSERV, and the like.
Unlike most similar products, Mailman gives each mailing list a web page
and allows users to subscribe, unsubscribe, and change their preferences
via the web. Even a list manager can administer his or her list(s)
entirely via the web. Mailman integrates many common MLM features,
including web-based archiving (though it also has hooks for external
archivers), mail-to-news gateways, bounce handling, spam prevention,
Majordomo-style email-based list administration, direct SMTP delivery (with
fast bulk mailing), digest delivery, virtual domain support, and more.
Mailman is written mostly in Python (with a smattering of C where necessary
for security purposes), and includes hooks to make it easily scriptable and
extensible. It is compatible with most web servers and browsers, and most
mail transfer agents (mail servers). Mailman's documentation may be found on
its website.
sgrep (structured grep) is a tool for searching and indexing text, SGML,XML
and HTML files and filtering text streams using structural criteria. The data
model of sgrep is based on regions, which are nonempty substrings of text.
Regions are typically occurrences of constant strings, SGML-tags, or meaningful
text elements, which are recognizable through some delimiting strings or the
builtin SGML, XML and HTML parser. Regions can be arbitrarily long, arbitrarily
overlapping, and arbitrarily nested.
Sgrep is a convenient tool for making queries to almost any kind of text files
with some well kown structure. These include programs, mail folders, news
folders, HTML, SGML, etc... With relatively simple queries you can display mail
messages by their subject or sender, extract titles or links or any regions
from HTML files, function prototypes from C or make complex queries to SGML
files based on the DTD of the file.
Spellutils is a suite of programs which are used to isolate some parts
or texts from various types of files and hand them over to another
program which may change the texts; it is typically a spell checker.
Afterwards the possibly changed text parts are copied back in place in
the original file.
1) The newsbody utility
The program newsbody is a utility to isolate the body part of a news or
email message in a separate file and then call some other program which
may change the body, and eventually merge the headers with the possibly
changed body. Optionally quotes and/or signature can be removed too, as
well as all or selected header lines can be kept.
2) The pospell utility
The program pospell is a utility to isolate the translations from a .po
file, then call some other program which may change the translations
(typically a spell checker), and eventually copy them back in place in
the .po file.
exmh is a TCL/TK based interface to the MH mail system. It provides
the usual layer on top of MH commands, as well as many other features:
MIME support! Displays richtext and enriched directly.
Color feedback in the scan listing.
A colour coded folder display with one label per folder.
Smart scan caching. News read/post. koi8-r support.
Facesaver bitmap display. Ispell support.
Background inc. You can set exmh to run inc periodically.
Searching over folder listing and message body.
A dialog-box interface to MH pick.
An editor with emacs-like bindings and MIME support.
Glimpse interface. You can index all your mail with glimpse
and search for messages by content.
User preferences. You can tune exmh through a dialog box.
User hacking support. A user library of TCL routines is supported.
IMPORTANT: exmh depends on the TK send facility for its background
processing. With TK 3.3, send now uses xauthority mechanisms by default,
unless you compile TK with -DTK_NO_SECURITY. Generally, this means that
you **MUST** must run xdm to start your Xserver.
Ploticus is script-driven, which makes it suitable for automated, unattended
uses, or for applications that will be run again and again. Ploticus might be
your choice for stylistic reasons or just because it suits the problem or
application. In general, ploticus is good at making graphs like you would see
in newspapers and news magazines, business publications, journals for medical
and social sciences, and so on.
You can also use Ploticus in combination with standard desktop tools, e.g.
generate data displays using ploticus then import SVG or PNG into PowerPoint,
Word, etc.)
Ploticus is not a function or mathematical plotting package like gnuplot, nor
would it be a good choice for applications where mathematical formulas or
scientific notations are to be rendered as an integral part of the data
display. Ploticus is also not intended as a "marketing" graphics package. Its
goal is to display data crisply without extra decoration and distracting
"dingbats" that cloud the picture. Thus there is little support for 3-D
effects, gradient backgrounds, and so on.
FreeBSD note: the binary is referred to as 'pl' in the source files, but
is installed as 'ploticus' so as to avoid conflicts with other ports.
