What is Evince?
Evince is a document viewer for multiple document formats. It currently supports pdf, postscript, djvu, tiff, dvi, cbr, cbz, etc.
The goal of Evince is to replace the multiple document viewers that exist on the GNOME Desktop with a single simple application. Evince is also capable of displaying, adding and editing PDF annotations (comments).
Remember zoom factor per document.
Remember position per document.
