Major Description
The HTML reports, although quite nice, do not scale. It is quite easy to generate a report.html so large that your browser will refuse to load it (or die trying)... a suggestion would be to take a page from JavaDoc and generate multiple html files with a unifying index.html page that
uses frames to present the whole thing.
Another approach would be to generate a PDF report. But although it would be easier to print (and that is a good requirement) I think the focus is more on navigation. If the amount of information in the report is too large printing won't help, but good navigation options (cross-links among the pages) will.
