Description: Because IBM donated source code estimated to be worth $40 million to the open source community, developers everywhere can now use Eclipse for building their development environments. How great is that? Specific modules called Eclipse plug-ins make interoperability almost seamless, and although Eclipse has been used to build a Java development environment, you could just as well use it to build HTML, JavaServer Pages (JSP), Extensible Markup Language (XML), or other language-development systems. In fact, a C/C++ development system has just been released.
