#shell script to generate "val" declarations for a theory's axioms
# also generates a comma-separated list of axiom names
#
# usage: make-rulenames <file>
#
#Rule lines begin with a line containing the word "extend_theory"
# and end with a line containing the word "get_axiom"
#Each rule name xyz must appear on a line that begins
# <spaces> ("xyz"
#Output lines have the form
# val Eq_comp = ax"Eq_comp";
