#
#    This builds "optimise", which is a programme to generate the set of possible optimum points
#    for a filter published in the Appendix of article /61.html
#
#    It also builds "series" which is a programme to calculate general information about
#    series of filter reduction ratios.
#    This makefile puts this information into a file "series.gh", which is included in optimise.cc
#
#    With further processing, the information in series.gh can also be used for other purposes, including
#    to generate the tables of reduction ratios published in article /42.html
