> (1)
> gsgw1037:/homes/arkady/CDSR> hod allocate -n 4 -d xx
> error: bin/hod failed to start.
> error: invalid 'clusterdir' specified in section hod (--hod.clusterdir): xx
> error: 1 problem found.
> Check your command line options and/or your configuration file /grid/0/kryptonite/hod/conf/hodrc
>    * Directory 'xx' does not exist - the message shuold say "Non-existing directory" (or "directory not found"), not "invalid"
>    * checking the configuration file will not help, the advice is confusing
>    * checking the command line options is the obvious thing to do -- the advise is unnecessary.
> (2) when hod does not understand the command, it prints the whole help options message -- which clobbers the screen and is confusing. It should give a meaningful message -- and may say "type hod help for more info"
