  28 # Quick and dirty but hopefully portable script to generate
  29 # command list from const COMMAND COMMANDS[] in command.c
  30 #
  31 # Usage: command_enum.sh [--with-help]
  32 #
  33 # Note: Only tested with GNU sed 4.0.9. Will anyway probably only work
  34 # with it, since we make use of many GNU extensions.
