- Add the parameters refentry.numbered, refentry.tocdepth to have the refentry titles numbered (default) or not.

- Add partintros handling. Needed to have a complete TDG compiled with `dblatex`.

- Add linking to areaset.

- Add emphasis rendering in programlisting and screen.

- Add some logic to handle the graphics in equations. Add the alt.use parameter.

- Add some XeTeX support. One can use `-b xetex` to compile with `xelatex`. The xetex.font parameter is added to allow the user to configure the fonts used by XeTeX. This feature may not work for some ranges of unicode characters. This aspect will be improved in a next release.

- A number of bug fixes.
