 \section{Acknowledgements}
 I would like to thank François Lafont who discovered quite a few bugs and made many suggestions that helped to improve the functionality of the package. Many thanks to Jin-Hwan Cho, the developer of \verb+dvipdfmx+, for contributing the \verb+dvipdfmx+ specific code, and to Walter Scott for proof-reading the documentation.
