> When you type help in the shell, it prints outs this long list of commands.  I think
it would be nice if the commands were organized into groups.  Seems like this would make the
information easier to digest.  So the output might look something like the following.
> {noformat}
> user@instance> help
> Table Administration
>  createtable - 
>  online -
>  offline -
> Data Modification
>  insert -
>  delete -
> Data Retrieval
>  egrep -
>  grep - 
>  scan -
> {noformat}
> Need to come up with a list of groups.
