=head1 DESCRIPTION

The GD.Text.Wrap plugin provides an interface to the GD::Text::Wrap
module. It allows multiples line of text to be drawn in GD images with
various wrapping and alignment.

See L<GD::Text::Wrap> for more details. See
L<Template::Plugin::GD::Text::Align> for a plugin that allow you to
draw text with various alignment and orientation.

Thomas Boutell wrote the GD graphics library.

Lincoln D. Stein wrote the Perl GD modules that interface to it
and Martien Verbruggen wrote the GD::Text module.

Craig Barratt E<lt>craig@arraycomm.comE<gt> wrote the original GD
plugins for the Template Toolkit (2001).

Andy Wardley E<lt>abw@cpan.orgE<gt> extracted them from the TT core
into a separate distribution for TT version 2.15.

These modules are looking for a new maintainer.  Please contact
