      NC HOST
          Show hosts in the farm.
          The hosts are also called 'slaves' or 'vovslaves'.
  
      USAGE:
          % nc hosts [OPTIONS]
  
      OPTIONS:
          -h        -- This help
          -c        -- Show consumable resources (e.g. RAM and CPUS)
          -f        -- Show list of slave fields
          -r        -- Show resources (legacy: pre-2013.03 format)
          -m        -- Show machine parameters (RAM, CPUfreq,...)
          -a        -- Show all known hosts (used with -m)
          -hw <HW>  -- Show only slaves that match HW constraints.
          -rule <SELRULE> -- Show only slaves that match the given selection
                             rule. Use "vovselect fieldname from slaves" for
                             the complete list of fields that can be used in
                             the rule. Example rules:
                                 "status==READY"
                                 "status!=OVRLD slots>8"
                             Can accept multiple constraints.
          -O <fmt>  -- Specify output format. The format string can contain
                       elements like @FIELDNAME@  or @FIELDNAME:WIDTH@  where
                       a negative width means left-align and a positive width
                       means right-align.
          -RAM      -- Same as -O "@NAME@ RAM/@RAM@ RAMFREE#@RAMFREE@
                                   RAMTOTAL#@RAMTOTAL@"
          -SLOTS    -- Same as -O "@NAME@ SLOTS/@SLOTS@ SLOTSTOTAL#@SLOTSTOTAL@
                                   CORES/@CORES@ CORESTOTAL#@CORESTOTAL@"
          -LOAD     -- Same as -O ...selection of fields about load...
          -INFO     -- Same as -O ...fields about host, arch, model, ...
          -ALL      -- Show all info about each slave (multiline output)
  
          -slowdown -- used only for testing
  
      EXAMPLES:
          % nc hosts

          % nc hosts -f
          % nc hosts -O "RAMFREE#@RAMFREE@ SWAP/@SWAP@ M=@MODEL@"
