sfApplicationMapPlugin is an easily configurable documentation-generator tool. It generates a graphical map of your applications using GraphViz software. It is useful when you want to have an overwiev of a specific application or of a whole project - each module/admin-module is marked with all actions and their comments. Take a look at the plugin readme tab to see some examples. You need to have GraphViz installed on your system to use the plugin.
