+     "A daemon that monitors directories for events, such as creating,
+deleting or modifying files.  It can monitor different sets of directories for
+different events.  When an event is detected, direvent calls a specified
+external program with information about the event, such as the location
+within the file system where it occurred.  Thus, \"direvent\" provides an easy
+way to react immediately if given files undergo changes, for example, to
+track changes in important system configuration files.")
