LifeLines is a genealogy program to help with your family history research. Its primarily strengths are its powerful scripting language and the ability easily import and export information in the GEDCOM format.
JMakeZtxt converts text files into the format needed by Weasel Reader (or CSpotRun). It is written in Java and should run on any machine that has a Java 2 JRE available for it. It has been most heavily tested on Linux and (lesser on) Windows.
