Licenses which "freely distributable" software may be put under include the GNU General Public License and GNU Library General Public License , as well as BSD-like licenses, public domain software, or other copyrights which do not impose any restrictions on distribution.

I realize that many pieces of software are probably not included in this list. I have only included software which have homepages on the web - I didn't want to point to FTP archives which often change. Also, the categorization of software is a bit inconsistent - any comments on improving the layout (I'm thinking a Yahoo-like layout eventually) would be appreciated. Also, send any updates to Erik Talvola - please include the name of the package, the web site, a description, and the license terms.

• The MET++ project addresses the design and implementation of a reusable multimedia framework. MET++ is an object-oriented application framework that supports the development of multimedia applications by providing reusable objects for 2D graphics, user interface components, 3D graphics, video, audio, and music. The collaboration between these objects is incorporated into a framework so that the class library builds a running application where the control flow, event dispatching, and message passing is preimplemented. MET++ manages the standard behaviour of a multimedia application such as time synchronisation and user interaction (file dialog, cut-copy-paste, multi-level undoable commands, etc.). A developper will customize the MET++ application framework by composing reusable objects, by building subclasses through inheritance, and by overwriting hook methods to add his specific functionality. - mild distribution restrictions - not enough for me to bump to the "non-free" section

Scripting languages

• Perl is an interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). It combines (in the author's opinion, anyway) some of the best features of C, sed, awk, and sh, so people familiar with those languages should have little difficulty with it. (Language historians will also note some vestiges of csh, Pascal, and even BASIC-PLUS.) Expression syntax corresponds quite closely to C expression syntax. Unlike most Unix utilities, Perl does not arbitrarily limit the size of your data--if you've got the memory, Perl can slurp in your whole file as a single string. Recursion is of unlimited depth. And the hash tables used by associative arrays grow as necessary to prevent degraded performance. Perl uses sophisticated pattern matching techniques to scan large amounts of data very quickly. Although optimized for scanning text, Perl can also deal with binary data, and can make dbm files look like associative arrays (where dbm is available). Setuid Perl scripts are safer than C programs through a dataflow tracing mechanism which prevents many stupid security holes. If you have a problem that would ordinarily use sed or awk or sh, but it exceeds their capabilities or must run a little faster, and you don't want to write the silly thing in C, then Perl may be for you. There are also translators to turn your sed and awk scripts into Perl scripts. - Artistic license
• Python is an interpreted, interactive, object-oriented programming language. It is often compared to Tcl, Perl, Scheme or Java. Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac, MFC). New built-in modules are easily written in in C or C++. Python is also usable as an extension language for applications that need a programmable interface. - freely distributable
• Tcl (Tool Command Language) is two things: a scripting language and an interpreter for that language that is designed to be easy to embed into other applications. As a language, it is much like UNIX shell languages. There is very little syntax and it is easy to learn. It is used to glue together building blocks built in system programming languages like C, C++, and Java. These building blocks appear as commands, or verbs, in the script language. It is easy to embed Tcl into a legacy program so you can script the behavior of that program and add in other building blocks like a GUI interface. The Tcl interpreter is written in C and has been ported to almost every computer platform.- BSD-like license
• Tk is a window system toolkit for building graphical user interfaces. Tk adds Tcl commands that create and manipulate widgets (i.e., windows). Tk makes GUI programming very easy, but at the same time it offers fine grain control and some sophisticated widgets so you can create great interfaces. In particular, its text and canvas widgets are very powerful. The text widget supports multiple fonts through a tag facility. Tags apply to ranges of text and can have different appearances as well as event bindings. Canvas widgets provide display-list graphics so you can efficiently manage thousands of lines, rectangles, ovals, images, text items, etc. The canvas also uses tags so you can easily add behavior to these light-weight items. More information on Tcl/Tk is available at The Tcl/Tk Consortium and at Scriptics Corporation- BSD-like license
• itcl - [incr Tcl] provides the extra language support needed to build large Tcl/Tk applications. It introduces the notion of objects, which act as building blocks for an application. Each object is a bag of data with a set of procedures or "methods" that are used to manipulate it. Objects are organized into "classes" with identical characteristics, and classes can inherit functionality from one another. This object-oriented paradigm adds another level of organization on top of the basic variable/procedure elements, and the resulting code is easier to understand and maintain. - freely distributable

• Perl/Tk (also known as pTk or ptk) is a collection of modules and code that attempts to wed the easily configured Tk 4 widget toolkit to the powerful lexigraphic, dynamic memory, I/O, and object-oriented capabilities of Perl 5. In other words, it is an interpreted scripting language for making widgets and programs with Graphical User Interfaces (GUI). (Examples of widget programs [not necessarily written in perl/Tk] include xterm, xclock, most web-browsers, etc.. They are programs with "GUI" interfaces of one sort or another and are subject to the effects of your window manager.) - freely distributable
• STk is a free R4RS Scheme interpreter which can access the Tk graphical package. Concretely, it can be seen as the standard Tk package where Tcl has been replaced by a Scheme interpreter. - very mild restrictions on commercial distribution
• PerlQt - Perl extension to allow use of the Qt toolkit - LGPL
• Rivet is a version of Tk, the graphical user interface programming interface commonly associated with Tcl. Rivet is different from Tcl/Tk because it uses no Tcl code evaluation, so it is suitable for embedding in other programming languages without the overhead of Tcl. Rivet contains programming interfaces for two languages: C and Python. The C interface provides the basis for embedding in other programming languages, while the Python interface is suitable for developing applications. Some people are interested in programming entire applications at the C level. Although this is possible, it does not come without difficulties (such as lack of documentation). - freely available
• Guile, GNU's Ubiquitous Intelligent Language for Extension, is a library that implements the Scheme language plus various convenient facilities. It's designed so that you can link it into an application or utility to make it extensible. Our plan is to link this library into all GNU programs that call for extensibility.- GPL
• Marx is an interpreted script language based on a C-like syntax. It provides a quick way of creating Graphical User Interfaces in X Window System. Besides GUI building, marx also provides simplified schemes for UNIX process control, direct shell command/script execution and inter-client communication via sockets. Engels is a lesser version of marx without the GUI extension. It is smaller in size and faster in startup, thus ideal for applications without GUI requirements. - GPL
