\title{The AMS \texttt{msam} symbol encoding vector}

\section{Introduction}

This document describes the AMS \texttt{msam} symbol encoding, which
is unfortunately called \texttt{TEX MATH SYMBOLS} in the \texttt{.tfm}
files although it has nothing to do with the encoding of
\texttt{cmsy}.  To overcome this difficulty use e.g.\ \texttt{msam10} 
like
\begin{quote}
  \textellipsis
  \verb|,\metrics\generalpltomtx{msam10}{msam10}{pl}{msam},msam10,|%
  \textellipsis
\end{quote}
in the \textit{file list} argument of \verb+\installfont+, or generate 
the \texttt{.mtx} file at some point before the \verb|\installfont| 
command.

Most glyph names were revised to match the names used in the
\texttt{.afm} files of the BlueSky Type~1 fonts, except for a few
cases where those glyph names were found to be confusing or
misleading.
