Pedfiddler v0.2, v0.3, v0.31 (2000-2003)

Pedfiddler is a set of programs to manipulate pedigree graphs. It can be used as a stand-alone version of the graphics facilities found in Pedpack. However, Pedfiddler is not fully compatible with Pedpack because it is not intended for analysis, but graphical purposes only.
