Well... it's actually &(article.content:h); and &(article.content); (note
the ampersands, not dollar signs)...
The added :h tells midgard to display the variable with some formatting
done to it, instead of directly. I think that :h will escape it, so that
it can will be displayed in HTML... that is, if you give it "foo<a href
='d'>a</a>", it will do the proper escapes to display that string in HTML,
instead of just dumping it into the output, which would give you "foo a",
where a is a link.

In their great knowledge, the midgard developers decided to modify the PHP
interpretor so that it will do that &(var); stuff without <? ?> around it.
This means that you can't just upgrade to PHP4, at least not till they add
the changes in to the PHP4 source, but its a small price to pay for the
convenience, I think. (and midgard 2 will have php4 support, so we won't
have to wait very long.)
Hope this helps,
Ben
