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

- Add `partintro`s 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.
