observe the convention of using files in directories called

<attribution>Terry Weissman</attribution>
|
|
<para>I've been asked to explain this ... way back when, when
|
|
Netscape released version 4.0 of its browser, we had a release
|
|
party. Naturally, there had been a big push to try and fix every
|
|
known bug before the release. Naturally, that hadn't actually
|
|
happened. (This is not unique to Netscape or to 4.0; the same thing
|
|
has happened with every software project I've ever seen.) Anyway,
|
|
at the release party, T-shirts were handed out that said something
|
|
like "Netscape 4.0: Zarro Boogs". Just like the software, the
|
|
T-shirt had no known bugs. Uh-huh.
|
|
</para>
|
|
|
|
<para>So, when you query for a list of bugs, and it gets no results,
|
|
you can think of this as a friendly reminder. Of *course* there are
|
|
bugs matching your query, they just aren't in the bugsystem yet...
