Great. So I convinced you to port the x_display (now that I got
more and more convinced that we can indeed bypass this step...).

OK; do you plan to support CVS access there so that I, David or
others can help you on certain points whenever this is appropriate?

Maybe, but wouldn't it be better to uncouple the TMGUI API
from using Perl or not? These should really be independent issues.
I am not against having some command line option in order to
support Perl (later we will do better, but this seems to be
a good temporary solution), but I think that the perl support
should not be mixed up with Qt.

I do not follow you completely.

We will do this, but later; I believe that we should not mix up
complicated changes inside TeXmacs with porting TeXmacs to another toolkit.
We will be able to do what you want, but I prefer to proceed by
clean steps before I get crazy. Don't forget that there are many other
developers and users with all sorts of questions, requests and problems...

Yes it is, you should enable hyphenation in the cells.
However, we do not have good Html <-> TeXmacs converters yet.
This really should be the first step before getting all this to work.
But I plan to work on this soon.
