** Description changed:

+ Please backport evince with libgxps support in precise.

+ Intro: libgxps is a GObject based library for handling and rendering XPS
+ documents.
+ 
+ OpenXPS or XPS stands for XML Paper Specification. It is based on XML
+ and it's a new electronic paper format originally developed by Microsoft
+ and it serves as a PDF alternative. XPS files are usually created using
+ "Microsoft XPS Document Writer" in Windows environments. It is now
+ standardized as an open standard document format.
+ 
+ Quoting Wikipedia: An XPS file is in fact a Unicoded ZIP archive using
+ the Open Packaging Conventions, containing the files which make up the
+ document. These include an XML markup file for each page, text, embedded
+ fonts, raster images, 2D vector graphics, as well as the digital rights
+ management information. The contents of an XPS file can be examined
+ simply by opening it in an application which supports ZIP files.
+ 
+ The OpenXPS document format specification supports features such as
+ color gradients, transparencies, CMYK color spaces, printer calibration,
+ multiple-ink systems and print schemas.
