Works very well...
I used to develop on Windows and used the amazing tool WinMerge. Then as I shifted my development to OSX I needed a WinMerge like tool. You would think it would be easy to find. Ha! I downloaded tools like DiffMerge, but realized it only allows single direction merging (making it quite useless). Other tools that I tried dont allow directory merging. Compare merge does what it is supposed to, and hence my choice for merging code.
