If you work with open source software of any kind ? whether at work or as a volunteer ? then you understand the importance of license compliance and keeping track of copyright ownership. But as a project grows, those tasks can get tricky, even when everyone is on the same page.

This weekend, why not set it up and dig into your source code ? you might be surprised at what you find.
