the Jabber IM network is built).
Its goal is to let you connect very easily (no account creation needed) to the
network and join various chatrooms, immediately.  It tries to look like the
most famous IRC clients (weechat, irssi, etc).  Many commands are identical and
you won't be lost if you already know these clients.  Configuration can be
made in a configuration file or directly from the client.
You'll find the light, fast, geeky and anonymous spirit of IRC while using a
powerful, standard and open protocol.")

send do not have digital signatures that are checkable by a third party.  Anyone
can forge messages after a conversation to make them look like they came from
you.  However, during a conversation, your correspondent is assured the messages
he sees are authentic and unmodified.  (4) Perfect forward secrecy: If you lose

Some platforms, notably Apple’s iOS and many versions of Android, impose
limits that prevent applications from running or accessing the network in the
background.  This makes it difficult or impossible for an XMPP application to
remain reliably connected to a server to receive messages.

In order for messaging and other apps to receive notifications, the OS vendors
run proprietary servers that their OS maintains a permanent connection to in
the background.  Then they provide APIs to application developers that allow
sending notifications to specific devices via those servers.

When you connect to your server with a client that requires push
notifications, it will use this module to set up a “push registration”.  When
you receive a message but your device is not connected to the server, this
module will generate a notification and send it to the push gateway operated
by your application’s developers).  Their gateway will then connect to your
device’s OS vendor and ask them to forward the notification to your device.
When your device receives the notification, it will display it or wake up the
app so it can connect to XMPP and receive any pending messages.")))
