CDML Extensions for Dreamweaver 1.0b is regarded as a distinguished and tractable set of XML and graphics files which allow you to use Macromedia Dreamweaver to edit your FileMaker Pro custom CDML files.

Designed to give users an editing environment for their custom CDML format files, CDML for DreamWeaver takes advantage of Dreamweaver's XML extensible architecture by teaching it what a CDML tag looks like and how it is constructed.

Leonardo is an integrated environment for developing and animating C programs. It is not intended to be a professional IDE, but it may be useful for visually debugging C programs and for creating algorithm animations in a declarative style. Leonardo allows you to compile and execute arbitrary C programs on the virtual CPU.

Programs can be executed both forward and backward; it is possible to reverse the execution of a program at any time by means of a control tool window.

Leonardo includes a text editor with syntax coloring, a compiler for the ANSI C language, a compiler for the Alpha language, a reversible virtual CPU, a very simple operating system for process, I/O and memory management, an integrated logic-based visualization system, and a simple graph editor.

Eclipse SDK 3.5 is designed as a useful open source software development project which aims at providing a robust, full-featured, commercial-quality, industry platform for the development of highly integrated tools.

The Eclipse project is composed of three subprojects, Platform, Java development tools (JDT), and Plug-in development environment (PDE). The Eclipse Platform is an open extensible IDE for anything and yet nothing in particular. It allows tool builders to independently develop tools that integrate with other people's tools so seamlessly you can't tell where one tool ends and another starts.

The JDT project provides the tool plug-ins that implement a full-featured Java IDE supporting the development of any Java application, providing refactoring support, incremental compilation, smart editing etc. The JDT project allows Eclipse to be a development environment for itself. The PDE project provides the mechanisms that enable the community to build plug-ins for eclipse.

The Eclipse SDK includes the Eclipse Platform, Java development tools, and Plug-in Development Environment, including source and both user and programmer documentation.

ScrIDE is a integrated development environment designed for scripting languages such as Python.

ScrIDE is a tool built on top of the open source IDEKit framework, and is designed to eventually replace PyOXIDE (another Python IDE built on top of IDEKit), but be flexible enough to work with other scripting languages.

At its simplest level, ScrIDE is programmers editor with the ability to run external processes.

This editor is a fully featured editor including such niceties as syntax coloring, popup function navigation, split panes, auto-indentation, and other such features. This is functionality provided by IDEKit.

ScrIDE, however, then has the ability to also run other shell commands, and format and display their output. The most obvious use of this is to run the file being edited in an external interpreter (ScrIDE theoretically also supports embedded interpreters).

The Eclipse Project is an open source software development project dedicated to providing a robust, full-featured, commercial-quality, industry platform for the development of highly integrated tools.

The mission of the Eclipse Project is to adapt and evolve the eclipse technology to meet the needs of the eclipse tool building community and its users, so that the vision of eclipse as an industry platform is realized.

Eclipse is a kind of universal tool platform - an open extensible IDE for anything and yet nothing in particular

The real value comes from tool plug-ins that "teach" Eclipse how to work with things - java files, web content, graphics, video - almost anything one can imagine. Eclipse allows tool builders to independently develop tools that integrate with other peoples tools so seamlessly you cant tell where one tool ends and another starts.
