title: Why is edoc unable to discover callbacks?
body: <p>For some time we are able to declare behaviour callback using -callback attribute instead of behaviour_info/1 (which in my opinion is more convenient). But, the edoc application seems to be unable to discover such attribute. Still, release notes suggested, that this issue was already fixed in version 0.7.10 (<a href="http://www.erlang.org/doc/apps/edoc/notes.html" rel="nofollow">http://www.erlang.org/doc/apps/edoc/notes.html</a>). Did anyone encounter similar problem and was able to overcome it?</p>
