Basically, it provides various, sophisticated methods for sifting through the thousands of marriage and baptismal records that can be in multiple files. It then takes the results of a search and loosely groups them by family. It is actually better suited for tracing families than just individuals.
It does NOT search the Internet, just files that are on your computer.
The program and help file are combined as one 'zip' file that can be
downloaded and unzipped to any directory you choose. I have not bothered
with a fancy installation program.
On first use, the 'Source' directory must be set from the 'File' menu. This tells the program where to find the text data files to be searched.
Warning: Use of this program IS addictive and can result in a lot of lost time<g>
