E-book manual: wrong format

[gdetrez]

The downloadable manual link, which is advertised as being an epub file, gives you a docbook xml instead:

~ ❯❯❯ wget http://openbuildservice.org/files/manuals/obs-reference-guide.epub
~ ❯❯❯ file obs-reference-guide.epub
obs-reference-guide.epub: XML document text
