#
# Note from cernlib source install web site:
#  "There are a number of products, mainly in "bin", which are 
#   not part of the standard build procedures. 
#   These include old stable products which are 
#   simply copied from previous releases as long as they keep working. 
#   There are the Patchy 4 programs (ypatchy etc.) 
#   and the Patchy 5 suite (nypatchy etc.). 
#   Other special programs may also be added as a 
#   convenience to certain users or as a backup. 
#   There may also be packages (e.g. Stdhep) which are 
#   not compiled at CERN and Cernlib is then only a distributor."
