\section{Sample Script}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

A source file \edef\temp{\noexpand\url{jhsample.tex}}\temp{} of this
document  may be compiled for JavHelp 2.0 with the following script.

\Verbatim
jhlatex jhsample
tex "\def\filename{{$1}{idx}{4dx}{ind}} \input  idxmake.4ht"
makeindex -o jhsample.ind jhsample.4dx
jhlatex jhsample
\EndVerbatim

The compilation produces the following files.

\begin{verbatim}
jhprog.class
jhsample-doc/
jhsample-doc/jhsample.html
jhsample-doc/jhsample.jhm
jhsample-doc/jhsample-jhi.xml
jhsample-doc/jhsample.hs
jhsample-doc/jhsample-jht.xml
jhsample-doc/jhprog.java
\end{verbatim}


The following instruction can be used for compiling the program.

\Verbatim
javac -classpath ${HOME}/jh2.0/javahelp/lib/jh.jar jhprog.java
\EndVerbatim


The outcome could be viewed through the following command.

\Verbatim
java -cp ${\home}/jh2.0/javahelp/lib/jh.jar:. jhprog
\EndVerbatim


\printindex
