   The Icecream daemon has to run on all nodes being part of the  Icecream
   compile cluster. It receives compile jobs and executes them in a chroot
   environment. The compile clients send  their  compile  environment  the
   first  time  they  send  a  job  to  a  particular  daemon, so that the
   environment of the daemon doesn't have to match the one of the client.

   The daemon also has to run on  clients  sending  compile  jobs  to  the
   Icecream  network.  If  a node should be able to send compile jobs, but
   never receive any, start the daemon with the option -m 0.

   All Icecream daemons need to have contact  to  the  Icecream  scheduler
   which controls the distribution of data between compile nodes. Normally
   the daemon will automatically find the right scheduler. If this is  not
   the  case  you  can explicitly specify the name of the Icecream network
   and the host running the scheduler.


   -n netname
          The name of the icecream network the daemon should  connect  to.
          There  has  to  be a scheduler running for the network under the
          same network name.

   -m max_processes
          Maximum number of compile jobs started in  parallel  on  machine
          running the daemon.

          Prevents jobs from other nodes being scheduled on this one.


   -d, --daemonize
          Detach daemon from shell.

   -l logfile
          Name of file where log output is written to.

   -s scheduler_host
          Name  of  host  running the scheduler for the network the daemon
          should connect to. This option might help if the scheduler can't
          broadcast  its  presence to the clients due to firewall settings
          or similar reasons.

   -v, -vv, -vvv
          Control verbosity of daemon. The more v the more verbose.

   -r, --run-as-user
          Force running the daemon with user rights. Usually you will need
          to run the daemon with root rights.

   -b env_basedir
          Base  directory  for  storing  compile  environments sent to the
          daemon by the compile clients.

   -u, --nobody-uid nobodyuid
          Id of user nobody. This user id  is  used  when  the  daemon  is
          dropping privileges.

   --cache-limit MB
          Maximum  size  in  Mega  Bytes  of  cache  used to store compile
          environments of compile clients.

   -N hostname
          The name of the icecream host on the network.
