File compare extension for Nautilus

Simple context menu file comparison extension for Nautilus 3 and above, inspired by the discontinued 'diff-ext' extension. By default it uses 'meld' to do the comparison and provides "Compare", "Compare to ~/foo/bar" and "Compare Later" in Nautilus context menu. Using the setup utility you can choose your favourite compare tool for one-on-one, three-way and multi-compare situations.
