Thank you Hans for this present !!

I just had to search the key to open this present,
as I used an old ConTeXt version
So I'm trying to switch to the texlive-2004 distribution
(choosing the GUTenberg installation set)
After some setup (m-bib has changed, ...)
I could try your code and...

	*** it does exactly what I need ! ***

Thank you very much !

Just a question.
As you keep calling this environment "\startline" I suppose
it is intended to be a standard option for "\startline"
(which is a great news as I think it is quite usefull for
numerous situations)
But as the new version of context is not yet in the texlive-2004
(or as texlive-2005 is not yet out ;-)
Would it not be a better idea to provide another environnement name
to avoid conflict with the future standard startline environment?

I tried to rename "startlines" to "startLines" with other hack,
but it doesn't seem to be suffisant (but I didn't expect to!).

Any way thank you for the solution !
