=item $option-value = $csv->option ($option-name)

Gets option value.

=item $csv->option ($option-name, $option-value, ...)

Set option value(s).  You can pass multiple option name-value pair
as parameter when setting.

=cut

## Inherited

=item $type = $csv->value_type

Gets value-type.  Value-type is package name of module
used for value modification.  A special value-type, ':none:'
is used to indicate values are non-structured (and no module
is automatically used).

=item $csv->value_type ([$type])

Set value-type.

=item $clone = $ua->clone ()

Returns a copy of the object.
