  14                 <description>&lt;p&gt;After a lot of hard work by its maintainer Alexandre Viau and
  15 others, the decentralized communication platform
  16 &lt;a href=&quot;https://en.wikipedia.org/wiki/Jami_(software)&quot;&gt;Jami&lt;/a&gt;
  17 (earlier known as Ring), managed to get
  18 &lt;a href=&quot;https://tracker.debian.org/pkg/ring&quot;&gt;its latest version&lt;/a&gt;
  19 into Debian Testing.  Several of its dependencies has caused build and
  20 propagation problems, which all seem to be solved now.&lt;/p&gt;
  21
  22 &lt;p&gt;In addition to the fact that Jami is decentralized, similar to how
  23 bittorrent is decentralized, I first of all like how it is not
  24 connected to external IDs like phone numbers.  This allow me to set up
  25 computers to send me notifications using Jami without having to find
  26 get a phone number for each computer.  Automatic notification via Jami
  27 is also made trivial thanks to the provided client side API (as a DBus
  28 service).  Here is my bourne shell script demonstrating how to let any
  29 system send a message to any Jami address.  It will create a new
  30 identity before sending the message, if no Jami identity exist
  31 already:&lt;/p&gt;

  38 # Send &lt;message&gt; to &lt;jami-address&gt;, create local jami account if
  39 # missing.
