9					my $column = Class::DBI::Column->new($name);
10
11					my $name = $column->name;

18					=head1 DESCRIPTION
19
20					Each Class::DBI class maintains a list of its columns as class data.
21					This provides an interface to those columns. You probably shouldn't be
22					dealing with this directly.
