Being that I'm a programmer, and programmers are lazy, I'm looking for a tool that can help me analyze code and refactor, decomposing conditionals mostly. I know that products like Resharper and Refactor Pro! can do this, but I was curious about FOSS alternatives.
A Google search turned this nifty tool that creates flowcharts, has anyone ever heard of any others like this?
Also, it would be nice if it could handle C#/VB.NET, but if not any ol' C-like language is good.
