Two suggestions for improvement:
- Add masthead_url = 'http://www.elpais.com/im/tit_logo_int.gif'
(e.g. before the INDEX line). This adds the logo of El Pais at the top
of the feed overview (which contains only one feed in this case)
- Activate 'no_stylesheets = True' (there are articles with '<style ...'
after the article content which gets included in the EPUB otherwise)
The name of the feed appears as "Unknown feed' which should be renamed somehow.
Good work!
