Teapot is a spread sheet program for UNIX, which uses modern concepts besides being portable and extensible, for instance three dimensional tables and iterative expressions.
It provides various output formats e.g. LaTeX and HTML.
There are executables in english, dutch and german available. They are started by typing "teapot_en", "teapot_nl" or "teapot_de". Just typing "teapot" starts the english version.
