Works for me too. Thanks for implementing this change.

There is the User Guide at 
http://www.erlang.org/doc/apps/tools/xref_chapter.html#5, but it's not 
all that much more helpful.

I am not aware of any other documentation / tutorials / examples.

I found that carefully reading the above two documents from start to 
finish, and trying a few self-constructed examples along the way, helped 
quite a bit.

I suspect the inaccessibility of the xref documentation is one of the 
reasons it isn't known and used more widely. Somebody should write a few 
introductory blog posts ...
