     Checking for changes to files.
 
 Note
-    The default is to use inotify (Linux specific, since 2.6.13)
+    The default is to use stat to get the timestamp.
 
-    Compiling with FOAM_USE_STAT (or if /usr/include/sys/inotify.h
-    does not exist) uses the stat function call.
+    Compile with FOAM_USE_INOTIFY to use the inotify
+    (Linux specific, since 2.6.13) framework. The problem is that inotify does
+    not work on nfs3 mounted directories!!
