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, cssutils, lxml, python-dateutil, BeautifulSoup, mechanize, dnspython, icu4c and podofo.
