Messages can be sent both to individual recipients and chatrooms. the recipient is either another jabber-account or a jabber-chatroom (use '-c' to tell sendxmpp it's a chatroom) =head1 OPTIONS B<-f>,B<--file> use configuration file instead of ~/.sendxmpprc B<-u>,B<--username> use instead of the one in the configuration file B<-p>,B<--password> use instead of the one in the configuration file B<-j>,B<--jserver> use jabber server instead of the one in the configuration file B<-r>,B<--resource> use resource for the sender [default: 'sendxmpp'] B<-t>,B<--tls> connect securely, using TLS B<-c>,B<--chatroom> send the message to a chatroom B<-s>,B<--subject> set the subject for the message to [default: ''] B<-m>,B<--message> read the message from (a file) instead of stdin B<-h>,B<--help>,B<--usage> show a 'Usage' message B<-d>,B<--debug> show debugging info while running =head1 CONFIGURATION FILE You may define a '~/.sendxmpprc' file with the necessary data for your xmmp-account, with a line of the format: @ e.g.: # my account alice@jabber.org secret ('#' and newlines are allowed like in shellscripts) B: for your security, sendxmpp demands that the configuration file is owned by you and has file permissions 600. =head1 EXAMPLE $ echo "hello bob!" | sendxmpp -s hello someone@jabber.org or to send to a chatroom: $ echo "Dinner Time" | sendxmpp -r TheCook --chatroom test2@conference.jabber.org =head1 SEE ALSO Documentation for the L module The jabber homepage: http://www.jabber.org/ The sendxmpp homepage: http://www.djcbsoftware.nl/code/sendxmmp (the xmmp homepage) =head1 AUTHOR sendxmpp has been written by Dirk-Jan C. Binnema , and uses the L modules written by Ryan Eatmon. =cut
