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

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

“The contents of an \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 <...>. For example, \hbox{@(tt) monospaced text@(/tt) would get the enclosed text in the TT font.” The above also holds for \text instead of \hbox.
