Rob Beezer \texttt{<[email protected]>} reported parse errors triggered
by xtpipes when jsmath compatible html pages are generated. Hence the
\verb=\Hcode{<!--l. \the\inputlineno-->}= has been commented out. Also
commented out is \verb= |<recall dvimath par|>= which would insert a
\verb=\sv:ignore= macro at the end of the \verb=DViMath=
configuration.

Changes to fix bugs reported by Rob Beezer's
\texttt{<[email protected]>}: Values of \verb=\@math= in the
configurations of \verb=$= and \verb=$$= have been changed from
\verb=span= and \verb=div= to \verb=\dlr= and \verb=\dlr\dlr=
respectively.  \verb=\dlr= will expand to \verb=$= character which is
needed by jsMath. Removed \verb=|<inline end-par comment|>= after
\verb=IgnorePar= in the configuration for \verb=$$=.

``The contents of an \verb=\hbox{}= are not rendered by jsMath, but
instead are used as plain text in the browser.  JsMath allows you to
include HTML commands through the (rather awkward) means of using
@(...) in place of \verb=<...>=.  For example, \verb=\hbox{@(tt)=
 monospaced \verb=text@(/tt)= would get the enclosed text in the TT font.''
The above also holds for \verb=\text= instead of \verb=\hbox=.
