From the developer:
Zarb is a carefully conceived program package for creating exercises, worksheets, tests and transparencies. The offered functions are varied and practical. Zarb seamlessly integrates its toolbars and menus with the most popular word processor Microsoft Word, and so combines the strengths of Word – working with fonts, tables, AutoTexts, grafics, etc. – with a whole range of new possibilities for educational purposes.
