What is open source?
	l “When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.” l The Open Source Initiative   http://opensource.org l The open source manifesto    The Cathedral and the Bazaar      Eric S. Raymond, 1997
