# The purpose of this script is to create metakind.h from a template
# and a list of theory kinds.
#
# This is kept distinct from kind.h because kind.h is a public header
# and metakind.h is intended for the expr package only.
#
# Invocation:

# mkmetakind template-file theory-kind-files...

# Output is to standard out.
