as i step you through example after example after example -- all of 'em pre-existing, including many from the library itself, and handled with solid honest-to-goodness working source-code -- you'll come to realize fully how _easy_ it is to detect headers (and even header-level!), and the people who insist on telling you "it's impossible" will seem curiously illogical and out-of-touch... oh yeah, feel free to recommend any e-text from the whole library as a "test-case" that you would like me to consider in detail! :+) (to be fair, test-cases should include scans to resolve any doubts.) thank you! enjoy your first full day of summer! 90 degrees in l.a.! -bowerbird
