Well, the website is up and coming. I have a page of examples that I
use to test new releases of Petal that I'll try to get loaded up this
week. The url used to <http://petal.mkdoc.org>; however, things have
apparently changed with the host company because that address is
bringing up a webarch.net homepage. Perhaps we'll hear more about this
development later. Be sure to read the POD for Petal::Doc::Petales. That
has lots of examples in it.

I agree although have so far been content to create condition
hierarchies in my templates since it's only been 2 options. This point
brings up in my mind the question of how is it done in TAL. I think that
they have a method of invoking Python directly but so far Jean-Michel
has avoided making Perl's interpreter available, a decision with which I
generally agree. However, it would be nice to have a solution to the OR
dilemma.

Oftentime, Jean-Michel suggests creating a custom modifier. This
technique is explained in more detail in the Petales doc I suggested
above.


Good luck and let us know what you end up doing,
William
