LifeLines is a genealogy program that runs on UNIX systems. It maintains genealogical records (persons, families, sources, events and others) in a database, and generates reports from those records. There are no practical limits on the number of records that can be stored in a LifeLines database, nor on the amounts or kinds of data that can be kept in the records. LifeLines does not contain built-in reports. Instead it provides a programming subsystem that you use to program your own reports and charts. The programming subsystem also lets you query your databases and process your data in any way. LifeLines uses the terminal independent features of UNIX to provide a screen and menu based user interface.
LifeLines is a non-commercial, experimental system that is use at your own risk software. I developed LifeLines for personal use and shared it with friends. Enough of a demand arose through word of mouth and internet, that I have made the LifeLines source code and other information freely available at two ftp sites, ftp.cac.psu.edu and hoth.stsci.edu. Though LifeLines is free in all its forms, I retain all rights.
