  40 # mozconfig2configure - Loads options from .mozconfig onto configure's
  41 #    command-line. See mozconfig-find for how the config file is
  42 #    found
  43 #
  44 #    The options from .mozconfig are inserted into the command-line
  45 #    before the real command-line options. This way the real options
  46 #    will override any .mozconfig options.
  47 #
  48 # .mozconfig is a shell script. To add an option to configure's
  49 #    command-line use the pre-defined function, ac_add_options,
  50 #
  51 #       ac_add_options  <configure-option> [<configure-option> ... ]
  52 #
  53 #    For example,
  54 #
  55 #       ac_add_options --with-pthreads --enable-debug
  56 #
  57 # ac_add_options can be called multiple times in .mozconfig.
  58 #    Each call adds more options to configure's command-line.
  59
  60 # Note: $_AUTOCONF_TOOLS_DIR must be defined in the script that includes this.
