DESCRIPTION
     Nice executes command with low scheduling priority.  If the

     priority for most processes is 0.

     The super-user may run commands with priority higher than
     normal by using a negative priority, e.g. `--10'.

     Processes that have been niced are marked specially in ps(1)
     listings.
