=head1 DESCRIPTION

This class models a text area, where users can type text.

=head1 INTERFACE

The interface is the same as the one described in
L<CGI::Test::Form::Widget::Input>, with the following additional attributes:

=over 4

=item C<columns>

Amount of displayed columns.

=item C<rows>

Amount of displayed text rows.

=item C<wrap_mode>

The selected work wrapping mode.

=back

=head1 BUGS

Does not handle C<wrap_mode> and C<columns> yet.  There is actually some work
done by the browser when the wrapping mode is set to C<"hard">, which alters
the value transmitted back to the script upon submit.
