What is Sanaviron?

The Sanaviron Project is an 2D drawing engine fully written in Python for represent composite vector graphics. This is
essentially a GTK+ Cairo based canvas. The effort focuses mainly on the design of budgets, invoices, labels and many
other types of commercial documents. Sanaviron offers a simple but powerful high level API that you can implement in
their programs. This widget can be used for flexible display of graphics and/or creating documents interactively.
Sanaviron is a GTK+/Cairo dependent component, so it is portable to many plataforms. Sanaviron is 100% pure Python,
but because the libraries used, it is easy to translate into ANSI-C using GObject mechanism and much easier to translate
into C++.
