This extension module allows to use an ssh connection to perform distributed
copy and installation of rpm packages over a network.

To use this module, edit /etc/urpmi/parallel.cfg and add an alias line as
follows :
  <name>:ssh:<node list separated by ':'>
or
  <name>:ssh(<default media>):<node list separated by ':'>
where:
  <name> is the "alias name" parameter of --parallel options of the
      urpm* tools,
  <default media> is the default --media parameter for this alias,
  <node list separated by ':'> is a list of nodes (network hosts),
      for example "node1:node2: ...:nodeN".

You can specify 'localhost' as a node name if you want to include
the server in the list of machines to be upgraded.
