LifeLines is an advanced genealogical system. You can store any kind and any amount of data in a LifeLines database, and you can process and generate output based on that data in any way and in any format. LifeLines supports GEDCOM; it imports and exports GEDCOM data. LifeLines has a unique approach to report generation. LifeLines has no built-in reports. Instead all reports are generated using report programs that are written in a report programming language. Because of its flexibility and programmability, LifeLines is frequently used for genealogy applications on the World Wide Web. WWW: http://lifelines.sourceforge.net/
