Class::Hook enables you to trace methods calls from your code to other classes. Instead of putting 'use Foo;' in your code, simply type 'use Class::Hook;'. The class Foo is unknown in your code. It will be magically caught by Class::Hook which will call Foo itself. You can see Class::Hook as a kind of relay. You can setup a subroutine to be called before any call to Foo->amethod and a subroutine to be called after the call. Your subs will receive all the information that Foo->amethod will receive, so you can trace everything between your code and Foo.

mem is a trivial pragma to either allow defining the module it is included from as being defined so that later classes or packages in the same file can use the package to pull in a reference to it, or to be able to call its import routine from a different package in the same file. With parameter assignments or other actions, it forces those assignments to be done, immediately, at compile time instead of later at run time. It can be use, for example, with Exporter, to export typed-sub's among other usages.

Email::Sender replaces the old and sometimes problematic Email::Send library, which did a decent job at handling very simple email sending tasks, but was not suitable for serious use, for a variety of reasons. Most users will be able to use Email::Sender::Simple to send mail. Users with more specific needs should look at the available Email::Sender::Transport classes. Documentation may be found in Email::Sender::Manual, and new users should start with Email::Sender::Manual::QuickStart. This module provides a very simple, very clean, very specific interface to multiple Email mailers. The goal of this software is to be small and simple, easy to use, and easy to extend.

This package supplies a set of functions that find the roots of polynomials. Polynomials up to the quartic may be solved directly by numerical formulae. Polynomials of fifth and higher powers will be solved by an iterative method, as there are no general solutions for fifth and higher powers. The linear, quadratic, cubic, and quartic *_roots() functions all expect to have a non-zero value for the $a term. If the constant term is zero then the first value returned in the list of answers will always be zero, for all functions.

The module is a probability based, corpus-trained tagger that assigns POS tags to English text based on a lookup dictionary and probability values. The tagger determines appropriate tags based on conditional probabilities - it looks at the preceding tag to figure out what the appropriate tag is for the current word. Unknown words will be classified according to word morphology or can be set to be treated as nouns or other parts of speech. The tagger also recursively extracts as many nouns and noun phrases as it can, using a set of regular expressions.

This module provides functions that deals with formatting data with Content-Type 'text/plain; format=flowed' as described in RFC2646 (http://www.rfc-editor.org/rfc/rfc2646.txt). In a nutshell, format=flowed text solves the problem in plain text files where it is not known which lines can be considered a logical paragraph, enabling lines to be automatically flowed (wrapped and/or joined) as appropriate when displaying. In format=flowed, a soft newline is expressed as " \n", while hard newlines are expressed as "\n". Soft newlines can be automatically deleted or inserted as appropriate when the text is reformatted.

xeartk is a tkgeomap application that uses the geomap::wdgeomap command to create an interactive map. The geographic data is from the xearth root window program. by Kirk Lauritz Johnson in an interactive widget. xeartk is not part of and does not require xearth. It only uses the outline data defined in file mapdata.c of the xearth source distribution. The cities are from factmonster. Adjust the map view by Shift-Double-Clicking or Shift-Dragging. Double click a dot to display information about the city there on the terminal.

MPEG Maaate (pronounce: ma:a:it) is a C++ toolkit to parse and analyse audio data in the compressed domain by analysing MPEG-1/2 Layers 1-3 audio files. It makes the encoded fields of an MPEG audio stream accessible (tier1) and provides some content analysis functions like silence detection (tier2). MPEG Maaate is designed in tiers: the first tier implements the parsing of the MPEG audio stream, the second tier implements the content analysis on the extracted field, and the third tier includes any applications that are based on the extracted content.

playmidi is a small, quick midi file player using the level two sequencer of the voxware 3.0 package to play on general midi devices or FM or Gravis Ultrasound. If no files are specified, playmidi will give a short summary of usage options. If more than one file is specified, you may skip to the next file while the current one is playing by pressing your interrupt (usually control-c) key. If you invoke playmidi while it is al- ready running, it will allow you to control the currently running invoca- tion until its death, after which time all waiting invocations fight to go first.

What Is QCad? QCad is a professional CAD System. With QCad you can easily construct and change drawings with ISO-texts and many other features and save them as DXF-files. These DXF-files are the interface to many CAD-systems such as AutoCAD (c) and many others. What is QCad not? QCad is no designer tool. That means you can not create any filled shapes nor any crazy freehand forms. Also you can not drag and drop the objects in the drawing with the mouse. If you find any bugs, send a report to bugs@qcad.org.
