I did a quick rewrite, but then fell prey to feature creep ;). So it's now
in Perl and produces HTML tables. It takes EXPLAIN output on STDIN and is
configured through a stylesheet.

        pgsql -U user -D database -c "EXPLAIN query" 2>&1 |
        ./explain > out.html

Or just call it with a text file:

        perl explain in.txt out.html

The sample is a bit doctored as I embedded the stylesheet in it so people
could preview from email if they wanted. Output HTMLs require the CSS
(Cascading Style Sheet) to be in the same dir as them by default.

It doesn't use any modules (which means it's icky embedded HTML ;) so it
should work on any *nix system by default. Pretty rough but should work.

Have fun.
