# file to be read by commander.p
# each line is turned into a structure entry   	(str)

#     	a usage-printing entry			(usg)
# 	and a command line reading entry	(clr)
# of these, the S, U and C can be disabled by >No S, etc.

# BND is essentially parameter-free; you only have to decide when to
# give up. For numerical reasons a clipping rule was introduced but it
# only very rarely makes any difference.
# the fudge procedure is not needed but is investigated as a research 
# possiblity.
