Done, please test.

Thanks, that is very much appreciated. A couple of things:

* [ and ] don't work with \Big; they work with \left/\right though. The
synonyms \lbrack and \rbrack should be supported.
* the input <math>\Bigg\mid abc \Bigg\mid</math> returns the same text,
without any TeX rendering.
* the absolute value symbol doesn't work after \left or \big, neither
in the form | nor in the form \vert (which should be supported).

I would still wish for an eqnarray* environment, to break long lines of
equations into separate lines.

All fixed. \Big [ in fact worked, it's just ] what is magical
(support for optional arguments in tex requires some magic,
I just forgot to cast proper spells on \Big)

\Bigg \mid throws syntax error now (what you saw was
IMG alt text - texvc accepted it thinking \mid is a delimiter,
while tex rejected it).

You mean something like {matrix} but with left alignment instead
of centering or more than that ?

Brion, please apply that patch.
Oh, and there's no need to copy texvc_test to all w/math/ directories.
It shouldn't even be built by default.

New patch is on test.wikipedia.org and in CVS. Ready to install on
production wikis when you say the word.

Okay, thanks. :)

Yes, and it should also use the larger display style rather than the
inline style for formulas, which makes a difference when you have
integrals, sums and limits.

In LaTeX it's called \begin{eqnarray*}...\end{eqnarray*} and in
AmsLaTeX they have \begin{align*}...\end{align*}. They're almost
identical, so if you support one you may as well throw in the other for
the same price. Syntax is the same as the matrix environment. The stars
are there because we don't want equation numbers.
