#
#shell script for adding signature and val declarations to a rules file
#  usage:  make-rulenames <directory>
#
#Input is the file ruleshell.ML, which defines a theory.
#Output is .rules.ML
#
#
#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"
# ENSURE THAT THE FIRST RULE LINE DOES NOT CONTAIN A "[" CHARACTER!
#The file RULESIG gets lines like	val Eq_comp: thm
#    These are inserted after the line containing the string INSERT-RULESIG
#
#The file RULENAMES gets lines like	val Eq_comp = ax"Eq_comp";
#    These are inserted after the line containing the string INSERT-RULENAMES
#The input file should define the function "ax" above this point.
