   this funny little program is based on Tom Wetmore's "genancc1"
   and generates a GEDCOM file with descendants of a chosen individual
   who have the same surname (usually this means male line descendants
   plus illegitimate children of daughters) plus their spouses.

   a truely good program would need to exclude cases of daughters'
   marriages with guys of the same surname but not related and include
   male line descendants who changed surnames */
