# File:
#    equations.txt
#
# Purpose:
#    This file is used as input for the eqn_regr_test.py script, which
#    exercises the eqn_test_driver SHARE executable.
#
#    This first version is a decent start, and exercises SHARE 57334, but it
#    will no doubt need some additional test cases.
#
#    Comments are lines that start with a '#'.  Comments may be added to the
#    end of a line if they start with '=#' since the parser tokenizes by '='.
