+      The EventLog library aims to be a replacement of the simple syslog() API
+      provided on UNIX systems. The major difference between EventLog and
+      syslog is that EventLog tries to add structure to messages.
+
+      Where you had a simple non-structrured string in syslog() you have a
+      combination of description and tag/value pairs.
