Dear all, we wrote a small program called gTybalt, which combines GiNaC, Root and TeXmacs. This yields a graphical user interface to GiNaC. Since the Root-package includes CINT, you basically have the same functionality as ginac-cint. In addition, gTybalt provides routines for plotting functions of one or two variables. The plotting routines are based on Root and are quite fancy. Furthermore by integrating TeXmacs, you get high-quality output, e.g. mathematical formulae are displayed using TeX fonts. TeXmacs is a what-you-see-is-what-you-get editor and the resulting formulae can easily be converted to LaTeX. At the present stage, the very first alpha-release of gTybalt is available. (This means: Don't expect too much !) You are welcome to visit the web-site http://www.fis.unipr.it/~stefanw/gtybalt.html for more information and the source code. Please note that at the moment gTybalt is based on OLD VERSIONS of GiNaC and CLN. You need GiNaC 0.6.4 and CLN 1.0.3. Best wishes, Stefan Weinzierl and Roberta Marani
