Dr. Geniusis (now Dr. Geo) is the Gnome interactive geometry software. It allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is useable in a teaching situation with students from primary or secondary level.
As of Sept 14 2002 version 0.5.15 is packaged in the main Debian archive.
Until version 0.6.0, Guile scriptability is a new feature. A DrGenius Guile Script - DGS - is an object which can be plugged in a figure, its action is determined by its contents, a guile script which can interact with other element of the figure.
A DGS can alter other object or process values.
