       description: >
-        "You can now easily generate a catlog of all books in your calibre library by clicking the arrow next to the convert button. The catalog can be in one of several formats: XML, CSV, EPUB and MOBI, with scope for future formats via plugins. If you generate the catalog in an e-book format, it will be automatically sent to your e-book reader the next time you  connect it, allowing you to easily browse your collection on the reader itself."
