What is a groupware ? A groupware is a program that allows several people to work together in a simpler and more productive way than only using email. A groupware is strongly network oriented and provides some tools making it possible to distant people to communicate in a synchronous or asynchronous way. For example, it will be possible for users to share files, or even to store them on a server and to work with them at the same time. A lot of tools can be integrated in a groupware. That's why it is so important to remain extensible.
