Optionally but strongly recommended

1. flair-geoviewer a plugin to flair for interactive geometry editing, debugging and 3D visualization
2. PIL (python imaging library) and the tk interaface for image exporting from geoviewer. Typically on various distributions they appear with the name

Version Numbering

• M: Major version, this number is increased by one only when a major modification in the structure of the program takes place. During the initial phase of development is 0.
• m: Minor version, this number is increased by one every time a addition in the program functionality is made. e.g. Adding new plotting forms, mechanism, databases etc.
• R: Release, this number is increased every time when bug fixes take place or minor changes in the functionality. e.g. Addition of extra fields in a form etc.

Installation

In case your system doesn't support the rpm, use the tar gzip file and follow the instructions in the README file. For specialised help on various OS, look first the FAQ.
