Thanks Tobbe, that was the solution. So if I understand you correctly,
the yaws function that invokes the foo module expects the out/1
function to return a certain tuple, whereas io:format/2 doesn't really
return anything?

If this is the case, is there anywhere where I can find anymore
detailed documentation on what return tuples are expected by the
invoking method?

Thanks for your help,

Ben

I think I may have found the answer to this in section 7.6 of the yaws
manual. Most of the return values are fairly intuitive. I was
wondering if there is some deeper infomation about the exact pattern
matches that would be expected on some of the return type, like for
example {content, MimeType, Content}.

Cheers,

Ben
