<erl> out(A) -> yaws_api:ssi(A#arg.docroot, ["/HEAD", "/TOPTAB"]). </erl>
is at least a *little* bit clumsy though. :)

I think the success of Open Source has been more to do with widespread
peer-review. More eyeballs on the code means more bugs are caught.

But one person's idea of a cool improvement is another person's cruft.
Why should I force my ideas on Klacke's project when it's clear that we
have different priorities? Maybe he doesn't want an integrated cookieless
user system based on a database of IP addresses with timeouts, whereas I
do. Maybe I could just take yaws and make my "improvements" to it, but
then I'd have Chris' Hacked Version of Yaws, which wouldn't be any better
than something original of mine. In fact it would probably be worse in
the long run, as I can barely follow his code as it rapidly progresses.

I think that's a bit of a pipe dream... in my experience, Open Source
projects are generally written and maintained by a small team of
developers, or even a single person; everyone else mainly just sends in
bug reports and suggestions. Collaborative design tends to result in a
'too many cooks spoil the broth' situation in the pursuit of a 'one size
fits all' solution.
Basically, if I were going to worry about duplication of effort, I'd worry
more about how every Erlang programmer writes their own to_upper/1 et al
helper functions because they aren't found in stdlib :)
