Hey,
Is this conceivably because align is in the amsmath package and we

This is for output in the notebook, so it's not in the doc.

This one seems to work (I presume it compiles in the pdf doc okay),
although the html does quite like the \intertext...
Here's the full doc for reference:
.. MATH::
:nowrap:
\begin{alignat}{2}
\intertext{Minimize:}
&z&\\
\intertext{Such that:}
x_v^t &\leq x_v^{t+1}& \forall v\in V,\ 0\leq t\leq n-2\\
y_v^t &\leq y_v^{t+1}& \forall v\in V,\ 0\leq t\leq n-2\\
y_v^t &\leq x_w^t& \forall v\in V,\ \forall w\in N^+(v),\ 0\leq t\leq
n-1\\
\sum_{v \in V} y_v^{t} &= t+1& 0\leq t\leq n-1\\
x_v^t-y_v^t&\leq u_v^t & \forall v \in V,\ 0\leq t\leq n-1\\
\sum_{v \in V} u_v^t &\leq z& 0\leq t\leq n-1\\
0 \leq x_v^t &\leq 1& \forall v\in V,\ 0\leq t\leq n-1\\
0 \leq u_v^t &\leq 1& \forall v\in V,\ 0\leq t\leq n-1\\
y_v^t &\in \{0,1\}& \forall v\in V,\ 0\leq t\leq n-1\\
0 \leq z &\leq n&
\end{alignat}

These are used in output, so not in the doc.

This one is commented out (actually the whole function is), so it's not in
the doc.

The one in padics is inside of a _mul_(), so it's not in the doc.
The big thing I'd like is consistency: If the html docbuild works, then the
pdf should as well and vice versa.
Best,
