 *                      Written by Freddy Ariës                             *
 *                                                                          *
 * ARexx script to find unrelated family trees in the database              *
 * It will detect all family trees within the database that have no links   *
 * (spouse, parent or child links) to other present family trees.           *
 * Eg. useful to find out if you forgot to add a link somewhere...          *
 *                                                                          *
 * This version uses (by default) the rexxreqtools.library (which requires  *
 * a version of reqtools larger than 2.0 and rexxsyslib.library)            *
 * If you do not have these, change the line 'usereq = 1' to 'usereq = 0'   *
 *                                                                          *
 * New (requested by Robbie): progress indicator, using rexxarplib.library  *
 *                                                                          *
