Dear all, for those who are interested, I put a new version of gTybalt on the web. (http://www.fis.unipr.it/~stefanw/gtybalt.html) gTybalt is a small program build on top of some other packages (GiNaC, TeXmacs, Root, ...) and provides basically TeX-type fonts output for GiNaC and some basic plotting routines. The installation of the new version has become a little bit more user-friendlier, no modifications or adjustment of TeXmacs or GiNaC are needed any more. Enjoy it, Stefan - To UNSUBSCRIBE, email to ginac-list@ginac.de with a subject of "unsubscribe".
