In mathematics, a semigroup is an algebraic structure consisting of a
set together with an associative binary operation. A semigroup
generalizes a monoid in that there might not exist an identity element.
It also (originally) generalized a group (a monoid with all inverses) to
a type where every element did not have to have an inverse, thus the
name semigroup.
Math::Expr parses mathematical expressions into a tree structure.
The expressions may contain integers, real numbers, alphanumeric
variable names, alphanumeric function names and most other characters
might be used as operators. The operators can consist of multiple
characters. The only limitation is that a variable or function
name may not start on a digit, and not all chars are accepted in
operation names.
Display runs a specified command over and over, printing the output
through curses(3X). The command can be compound and the delay
between executions is settable on the command line. The output
from the command had better fit on a single screen, of course.
This can conflict with the application of the same name from the
graphics/ImageMagick port/package.

A cross-platform GUI editor, written in Python. It enables you to
both create and edit metalinks in a user friendly fashion. The
editor can automatically enter info about file name, file size,
hashes & chunk checksums by scanning a local file.
Net::vCard - Read and write vCard files (RFC 2426). vCard files hold
personal information that you would typically find on a business card.
Name, numbers, addresses, and even logos. This module can also serve as a
base class for other vFile readers.
Open Asset Import Library (short name: Assimp) is a portable Open Source
library to import various well-known 3D model formats in a uniform manner.
The most recent version also knows how to export 3d files and is therefore
suitable as general-purpose 3D model converter. See the feature list.
Ayttm is an instant messaging (aka chat) client that provides all-in-one
chat functionality for several major instant messaging services from one
simple program. Ayttm "Contacts" allow you to refer to several accounts of
the same person from a single contact name, making it one of the cleanest
and simplest clients to use.
choparp is a easy-to-use proxy arp daemon. It watches arp request pack-
ets visible on the interface specified by argument if_name, and sends
proxy arp reply to the sender if the arp request queries the MAC address
(ethernet hardware address) for the network speicified by net_addr and
net_mask.
This module handles loading and saveing of .torrent files as well as
providing a convenient way to store torrent file info in memory. Most
users of the module will most likely just call the new method with the
name of a existing torrent file and use the data from that.
H.323 Plus (or, "H323plus") is a multi-platform H323 Video Conferencing
library formerly known as OpenH323. The new name was chosen to reflect
the fact that the open source H.323 project now contains even
more more functionality than ever before.
