OK. If you want, I can add a "dot" (or rather "graphviz") entry to
the extern systems for TeXmacs. By the way, if you use extern files,
then it may be a good idea to use standard temporary files and delete them.

If I have time, then I might also implement a "black box" facility,
with the capacity of delegating typesetting to an extern system.
In a first stage, this will not be interactive, but it might be
nice for graphviz. I plan to reuse the standard interface techniques
used for cas' in order to do so. In other words, you may reuse what
you have done so far.

Thanks; this seems cool. I probably should add a facility to
specify optional arguments on the command line, which should allow
you to clean things up a little bit. For instance, this would allow
you to write

        texmacs -b texmacs-printer.scm -[ *.tm -]

and retrive the arguments a list, using a dedicated function
which has to be added as a scheme primitive. I don't know when
I will have time for this, so you actually may want to do this yourself.
After such a cleaning up, I would be happy to include your script in
the main distribution. Don't forget to add license information if
you would like this to happen.

Yours, Joris
