  26 # generated with mph which can be found in pkgsrc/devel/mph.
  27 # If you change the directives or keywords (adding, deleting, reordering) you
  28 # need to create new tables and hash functions (directive_hash, keyword_hash).
  29 #
  30 # The following changes have been made to the generated code:
  31 #
  32 #       o prefix the names of the g, T0 and T1 arrays with 'directive_'
  33 #         resp. 'keyword_'.
  34 #
  35 #       o make the type of the tables 'const [un]signed char' (if you change
  36 #         anything make sure that the numbers fit into a char).
  37 #
  38 #       o make the hash function use the length for termination,
  39 #         not the trailing '\0', via the -l flag in emitc and some editing
  40 #         (only for directive_hash).
