It's very nice to have a document describing the format like this, although I
think it can be improved.

When this md file is converted to HTML for viewing, the examples will only be
displayed in "code block" style if they are indented one more level:


The format for recipe result for compile failures is:

    {
        'report': {
            'result': {
                'rev1': 'passed',
                'rev2': 'failed'
            }
        }
    }

look when converted to HTML by using tools like http://dillinger.io/.

Yes. It does look much better now. Thank you : )
