Where can I find boost: fusion articles, examples, guides, tutorials?

I'm going to go ahead and shamelessly duplicate this question because the accepted answer is essentially "no, no guides" and it's been almost a year since it was asked. Does anyone know of any helpful articles, guides, tutorials, etc. For boost :: fusion, besides the barebones documentation at boost.org? (which I'm sure is great as a link after you get to know the library.) I'm completely open to, say, linking to a book on Amazon. Was looking for this myself now, but all I came up with was green tea. Top links on Google aren't that much better.
