This is the \textit{\revtex~4 Command and Options Summary}. It details
usage for many of the new commands and options that are available in
\revtex~4. Please see the \textit{\revtex~4 Author's Guide} for
complete information on how to use \revtex~4.  Class options for the
\verb+\documentclass+ line are marked with square
brackets. Environments are indicated by \verb+\begin{&lt;env&gt;}+ and always
require a matching \verb+\end{&lt;env&gt;}+.
