\SectionX{About techexplorer: Introductory and Professional Editions}
\par
The Introductory Edition is a viewer for a large subset of TeX, LaTeX, and
AMS-LaTeX. It also contains some basic, experimental support for the
Mathematical Markup Language Specification, though that support is far from
complete and is not documented here. 
\par

The Professional Edition includes all the features of the Introductory Edition and adds: 

\begin{itemize}
\item A scripting interface for developers who wish to programmatically control
techexplorer from Java or JavaScript. 
\item An add-in interface for authors who want to interactively send information to
other applications. 
\item Printing of full documents displayed by techexplorer. 
\item Searching, with all matches selected.
\end{itemize}
