<title>Embedding LaTeX Math in AsciiDoc dblatex documents</title>

<simpara>You can include LaTeX math equations in AsciiDoc documents that are
processed by <ulink url="http://dblatex.sourceforge.net/">dblatex</ulink>. The AsciiDoc
<emphasis>latexmath</emphasis> macros and passthrough blocks generate DocBook

containing the LaTeX markup which is processed by <emphasis>dblatex</emphasis>.</simpara>
