What it does

Checks that IEEE papers use IEEEeqnarray instead of align, split, or similar alignment environments.

Why is this bad?

The IEEE template provides a dedicated command for multi-line equations, IEEEeqnarray.

Example

\begin{align}
  a &= b
\end{align}

\begin{IEEEeqnarray}{rCl}
  a & = & b
\end{IEEEeqnarray}
