There are two streams of creativity that come together to create a free or open-source software application. The first, and most obvious to the majority of developers, is the set of bits that make up the source code for the application. But equally important to the political aspirations behind open source is the second stream: the legal craft that goes into making up the license for the software. If, like most developers, you're a bit shaky on this second part, help is as close as the publications of the
Software Freedom Law Center.
