=head1 NAME
 | 
						|
 | 
						|
B<gettab> - select table rows, based on attribute criteria, and display specific attributes.
 | 
						|
 | 
						|
=head1 SYNOPSIS
 | 
						|
 | 
						|
B<gettab> [B<-H> | B<--with-fieldname>] I<key=value,...  table.attribute ...>
 | 
						|
 | 
						|
B<gettab> [B<-?> | B<-h> | B<--help>]
 | 
						|
 | 
						|
=head1 DESCRIPTION
 | 
						|
 | 
						|
The B<gettab> command uses the specified key values to select a row in each of the tables requested.
 | 
						|
For each selected row, the specified attributes are displayed.  The B<gettab> command can be used instead
 | 
						|
of B<nodels> for tables that are not keyed by nodename (e.g. the B<site> table), or to select rows based
 | 
						|
on an attribute value other than nodename.
 | 
						|
 | 
						|

						|
 |

 | 
						|
 | 
						|
=item B<-H|--with-fieldname>
 |

 | 
						|
one table.attribute is requested.
