The screenshot seems very nice.

Yes; I assume that you currently use the mycas technique?
When you have a working interface, then I can add the necessary support
to the main TeXmacs distribution. After that, you may write your
own style file and scheme commands.

Hmm, I see... I have to think a bit about this.
I either have to modify the verbatim format slightly or
add a new format.

Andrey: what do you think about this.

Yes, please put this online or send it as an attached file to me.

In fact, we have the plan to add more command line tools for conversions.
One good TeXmacs command line option would be to let it execute a scheme
file and die. The new tendency is also to write as much of the converters
as possible in scheme; this will allow you to do certain types of
conversions (independent from the typesetter) without launching TeXmacs.
However, we did not find time yet to implement all this.
