+# == Synopsis
+#
+# mauvesend: send alert(s) to a given alert station
+#
+# == Usage
+#
+# mauvesend [destination]
+#   [--source | -o <source>] [--replace | -p] [--verbose | -v]
+#   [--id <alert ID> [alert options] ... ]
+#
+# <destination>:
+#   where the alert should go, can be one of:
+#     SRV record from DNS (we add _mauvealert._udp to record name)
+#     normal hostname (i.e. A record)
+#     IP address:port number
+#
+#   if no destination is supplied, reads parameter from file 
+#   /etc/mauvealert/mauvesend.destination (otherwise throws an error).
+# 
+# --source | -o <source>:
+#   identify the source of the alert (defaults to hostname, but you might
+#   want to name your monitoring systems more explicitly).
+#
+# --replace | -p:
+#   Send an update replacing all other alerts for this source - any previous
+#   alerts not specified in this update are assumed to be cleared.  If you
+#   specify this option, you don't have to supply *any* alerts to raise or 
+#   clear (in which case all alerts from that source will be cleared).
+#
+# --verbose | -v:
+#   If you specify this option once, it will print the transmission ID
+#   of the packet for debugging.  If you specify it twice, it will print
+#   the entire data structure.
+#
+# You can specify any number of alerts in an update - every time you specify
+# --id starts a new alert.
+#
+# --id | -i <alert ID>:
+#   alert ID; unique specified for each alert raised.
+#
+# --summary | -s <summary>:
+#   text for humans describing the nature of the alert, first 100 characters
+#   are only ones guaranteed to make it to pagers, twitter, SMS etc.
+#
+# --detail | -d <detail>:
+#   HTML fragment describing the alert in more detail, no limit on length.
+#
+# --subject | -u <subject>:
+#   set the subject of the alert (i.e. the server/entity that this alert
+#   concerns).
+#
+# --clear | -c <time>:
+#   mark the alert to be cleared at the given time, or +N where N is a number
+#   of seconds, or 'now'.  If not supplied, the alert is deemed to be raised 
+#   until explicitly cleared.
+#
+# --raise | -r <time>:
+#   mark the alert to be (re)raised at the given time.  If not supplied, the
+#   alert will be raised immediately.
+#
