-# NAME
-# mauveclient - send alert(s) to a given alert station
-#
-# SYNOPSIS
-# mauveclient [<destination>]
-# [ --help | -h ] [ --manual | -m ] [ --version | -V ]
-# [--source | -o <source>] [--replace | -p] [--verbose | -v]
-# [--id <alertid> ... ]
-#
-# OPTIONS
-# <destination> Where the alert should go. This can be either a hostname or
-# an IP address, and optionally a port, separated by a colon.
-# The default port is 32741.
-#
-# If no destination is supplied, the value from the file
-# /etc/mauvealert/mauveclient.destination is used. If no
-# destination can be determined, an error is raised.
-#
-# If a hostname is given and no port is specified, SRV records
-# are used to determine where the alerts should go to. The SRV
-# prefix is _mauvealert._udp. If no SRV records are found, A
-# records are used instead.
-#
-# IPv6 addresses can be used, but must be enclosed in square
-# brackets, e.g. [2001:41c8::12].
-#
-# --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.
-#
-# --help, -h Display a short help message, and exit.
-#
-# --manual, -m Display this manual, and exit.
-#
-# --version, -V Display the version number for Mauve and exit.
-#
-# You can specify any number of alerts in an update - every time you specify
-# --id starts a new alert.
-#
-# --id, -i <alertid> Unique specified for each alert raised. This should
-# be unique on a per-source basis, i.e. for an
-# individual application or host.
-#
-# --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). If no subject is
-# specified, it is assumed to be the same as <source>,
-# detailed above.
-#
-# --raise, -r <time> Mark the alert to be (re)raised at the given time.
-# If no time is supplied, "now" is assumed. See
-# SPECIFYING TIMES below for the format of <time>.
-#
-# --clear, -c <time> Mark the alert to be cleared at the given time. If
-# no time is specified, "now" is assumed. See
-# SPECIFYING TIMES below for the format of <time>.
-#
-# SPECIFYING TIMES
-#
-# Times can be specified for an alert to be raised or cleared. This can be
-# specified as any time in the past or future. The format is + or -, followed
-# by a number, followed by a letter determining the units, one of s, m, h, d,
-# representing seconds, minutes, hours, and days, respectively. If no units are
-# specified, seconds is assumed. If no sign is specified, "+" is assumed.
-#
-# Some example times are:
-#
-# now Immediately
-# 10 In 10 seconds time
-# +10m In 10 minutes time
-# -10h 10 Hours ago
-#
-# SENISBLE USAGE
-#
-# Mauve uses UDP to transmit data, which means that there is no guarrantee a
-# single packet will reach the server. Therefore:
-#
-# * The host/application should send "raise" notification regularly until the
-# alert clears, whereupon it should regularly send "cleared" notifications.
-#
-# * When setting a heartbeat-type alert, make sure that the raise time is more
-# than double the period of the "clear" notifications. For example, if the
-# host is sending a clear every 120 seconds, the raise time should be
-# greater than 240 seconds, preferably greater than 360 seconds to allow for
-# packets going missing, reducing the likelihood of false alerts.
-#
-# Try to convey salient details about the alerts in the relevant fields. A
-# typical short alert from Mauve might read
-#
-# RAISED: <subject>: <summary> -- <source>
-#
-# Make sure that the alert will be understood with just those three fields
-# displayed.
-#
-# * Keep the summary brief and salient.
-#
-# * Keep the summary constant, unless there has been a material change to the
-# nature of the alert. Mauve may re-send any messages when the subject
-# changes. If something is changing quickly, like load averages, best not
-# to put them in the summary.
-#
-# * Make sure that the subject is set correctly. Remember if no subject is
-# set, then the source of the alert is used instead.
-#
-# * Make sure that the source is correct too -- nothing worse than an alert
-# that comes in with an ambiguous origin.
-#
-# * The alert ID is used internally by Mauve to keep alerts consistent. This
-# must be unique on a per-source basis. It is OK to have many alerts with the
-# ID "heartbeat" as long as the source of the alert is different in each case.
-#
-# The raise and clear times can be specified, if needed, but generally leaving
-# them empty, i.e. setting them to "now" is sufficient. Mauve remembers when
-# an alert is first raised.
-#
-# EXAMPLES
-#
-# To raise an alert:
-#
-# mauveclient -s smtp-out-1.example.com -i mailqueue \\
-# -d "Mail queue has <b>54232</b> messages in it. That's <em>LOADS</em>" \\
-# -u "Mail queue too big on outgoing SMTP server" -r
-#
-# To clear an alert:
-#
-# mauveclient -s smtp-out-1.example.com -i mailqueue -c
-#
-# To create a "heartbeat" alert, i.e. one that says "Currently OK, but raise in the future if nothing more is heard":
-#
-# mauveclient -i heartbeat -d "No heartbeat received for 1.2.3.4. Could be down!" -s "heartbeat failed" -c -r +10m
