\section{Changes}
29 Dec 1993, v1.30: Created file.
3 Jan 1994, v1.301: Renamed some of the glyphs, added fakes for
\texttt{arrowverttp} and friends.
8 Jan 1994, v1.304: Renamed \texttt{similareq} to \texttt{similarequal}.
9 Jan 1994, v1.305: Renamed some glyphs to use the same names as Lucida
New Math.
16 October 2000, v\,1.915: Updated markup (made it a \LaTeXe\
document!). (LH)
20 November 2000, v\,1.915: Added test for whether the \texttt{product}
glyph exists before setting the \textit{textoperatorsize}, using
value corresponding to \texttt{cmex10} if it doesn't. Changed
\verb|\wideaccent| to call the widest glyph \textellipsis\texttt{widest}
instead of \textellipsis\texttt{widerr}. Changed glyph name
\texttt{arrowdblvertex} to \texttt{arrowvertexdbl}. (LH) Reported by
Alejandro L\'{o}pez-Valencia.
