Project File Structure
The file structure of our projects differ a good bit from traditional SVN repositories because we are a small group of core developers and because we do not feel the overhead of SVN:Externals is necessary.
Each project receives it's very own folder and may contain sub-folders for underlying components, but any source code files which are common to other projects (such as Classes and Libraries) are stored above the project folder. Common components are stored one level above the project folders and referenced via relative paths / directory traversals (eg. "..\..\Libraries\ClassName.h").
