+recursive directory notifications built as a wrapper around fsnotify (golang)

+
+This is a thin wrapper around https://github.com/fsnotify/fsnotify instead of only monitoring a top level folder,
+it allows you to monitor all folders underneath the folder you specify.
+
+Example:
+--------
+(error handling omitted to improve readability)
+```
+    import "github.com/dietsche/rfsnotify"
+
+//rfsnotify works exactly like fsnotify and implements the same API.
+    watcher, err := rfsnotify.NewWatcher()
+
+//rfsnotify adds two new API entry points:
+    watcher.AddRecursive("/tmp/")
+    watcher.RemoveRecursive("/tmp/")

-fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications.
