Calibre is meant to be a complete e-library solution. It includes library
management, format conversion, news feeds to ebook conversion as well as
e-book reader sync features.

Calibre is primarily an ebook cataloging program. It manages your ebook
collection for you. It is designed around the concept of the logical book,
i.e. a single entry in the database that may correspond to ebooks in several
formats. It also supports conversion from a dozen different ebook formats to
LRF and EPUB. A graphical interface to the conversion software can be
accessed easily by just clicking the "Convert E-books" button.

This requires pysetuptools, lxml, python-dateutil, BeautifulSoup, ClientForm, 
mechanize, dnspython, and podofo.

Optional: unrar and openjpeg.

Note: This package conflicts with pyPdf, cssutils, and CherryPy, as it 
provides these packages (available at slackbuilds.org).  Calibre also 
provides odfpy and django-tagging (not available at slackbuilds.org).
