$program  --  Kannel monitoring module for 'mon'

  This Perl script is a custom monitoring module for mon, the system monitoring
  tool, see http://www.kernel.org/pub/software/admin/mon/. The module watchs for
  availibility of the Kannel SMS gateway, basicaly it checks the state of the 
  connected SMSC links. In case of an error it will returns the affected SMSC IDs
  of the links.

USAGE:  $program [options] hosts...
    
  where options can be any of:

  -h                this help message
  -n "smsc-ids..."  a list of smsc-ids that should be ignored by the test
  -s URI            the URI on the hosts containing the status-document (default: $statussheet)
  -p port           the port to connect to (default: $port)
  -S                use https:// scheme to access the URI (via SSLv3) (default: http://)
  -P password       the status-password (default: $password)
  -f file           local XML file to read (mainly for testing)
  -v                verbose output
  -i                info mode, displays the whole information to stdout

  Examples: 

    $program -i -v -n "smpp_foo smpp_bar" kannel.foobar.com

    Checks out the status page status.xml (default) on kannel.foobar.com, 
    port 13000 (default) without password. It lookes for the general 
    status as well as for the status of the smsc-connections but ignores 
    error on the smsc-ids smpp_foo and smpp_bar. The whole status is displayed. 
    The failure messages are verbose.

    $program -i -v -f status.xml -n "smpp_foo smpp_bar"

    The same as above, but reading from a local status.xml file

    $program -p 13001 -P secret kannel.foobar.com
          
    Looking for status on port 13001 with password "secret". Only failing 
    smsc-ids are displayed.
