+'''Low-level interface to the Linux inotify subsystem.
+
+The inotify subsystem provides an efficient mechanism for file status
+monitoring and change notification.
+
+This package provides the low-level inotify system call interface and
+associated constants and helper functions.
+
+For a higher-level interface that remains highly efficient, use the
+inotify.watcher package.'''
