+// Run an external 'MRTG-compatible' script, and return it's values
+// TARGET !/usr/local/bin/qmailmrtg7 t /var/log/qmail
+
+// MRTG Target scripts return 4 lines of text as output:
+//    'Input' value - interpreted as a byte count (so multiplied by 8)
+//    'Output' value - interpreted as a byte count (so multiplied by 8)
+//    'uptime' as a string
+//    'name of targer' as a string
+// we ignore the last two
+
+// NOTE: Obviously, if you allow anyone to create maps, you are
+//       allowing them to run ANY COMMAND as the user that runs 
+//       weathermap, by using this plugin. This might not be a 
+//       good thing.
+
+//       If you want to allow only one command, consider making
+//       your own datasource plugin which only runs that one command.
