+=head1 NAME
+
+Tk::Zinc - TkZinc is a kind of Canvas which proposes many new functionnalities
+
+=for category Tk Widget Classes
+
+=head1 SYNOPSIS
+
+I<$zinc> = I<$parent>-E<gt>B<Zinc>(?I<options>?);
+
+=head1 DESCRIPTION
+
+I<Zinc> widget is very similar to Tk Canvase in that it supports
+structured graphics. Like the Canvas, TkZinc implements items used to
+display graphical entities. Those items can be manipulated and bindings can be
+associated with them to implement interaction behaviors. But unlike the
+Canvas, TkZinc can structure the items in a hierarchy (with the use of
+group items), has support for affine 2D transforms (i.e. translation, scaling, and
+rotation), clipping can be set for sub-trees of the item hierarchy, the item set
+is quite more powerful including field specific items for Air Traffic systems and
+new rendering techniques such as transparency and gradients.
+
+Since the 3.2.2 version, TkZinc also offers as a runtime option, the support
+for openGL rendering, giving access to features such as antialiasing, transparency,
+color gradients and even a new, openGL oriented, item type triangles.
+
+TkZinc full documentation is available as part of the Zinc software as a
+pdf file, B<refman.pdf> and html pages B<refman/index.html>.
+
+As a complement to the reference manual, small Perl/Tk demos of TkZinc are
+also available through a small application named zinc-demos, highly inspired
+from the widget application included in Tk. The aim of these demos are both
+to demonstrates the power of TkZinc and to help newcomers start using
+TkZinc with small examples.
