# To add new pragmas, first add the name and other relevant attributes
# of the pragma to the "pragma_def" object below. Then run this script
# to generate the C-code for the lookup table and copy/paste the output
# of this script into the appropriate spot in the pragma.c source file.
# Then add the extra "case PragTyp_XXXXX:" and subsequent code for the
# new pragma.
