[NTG-context] multiple line comments

Dear all, It's a bit tiring to start many lines always with %. Is it possibile to have multiple line comments like in C \* comments here *\ I wasn't able to find anything like it in manual. In this case, what about a \startcomment \stopccoment syntax? Or maybe is it possible to have a user defined command? \comment{ comments here } Thanks -a- Andrea Valle DAMS - Facoltà di Scienze della Formazione Università degli Studi di Torino http://www.semiotiche.it/andrea andrea.valle@unito.it
