                                 <p>Zathura is an awesome program. Out of the box it's basically nothing, but with extensions it can read many different formats, such PDFs, DjVu, comic books and more. It has Vim like keybindings, so it will take no getting used to if you're using a Vi like editor already.</p>

It can draw any kind of shapes you can think of including images, handle colors, transparency, and together with Pango it can also load fonts, draw text and even has XML like markup for colors and formatting. It is useful for both X and Wayland buffers.</p>
