michael@0: # mozconfig2configure - Loads options from .mozconfig onto configure's
michael@0: #    command-line. See mozconfig-find for how the config file is
michael@0: #    found
michael@0: #
michael@0: #    The options from .mozconfig are inserted into the command-line
michael@0: #    before the real command-line options. This way the real options
michael@0: #    will override any .mozconfig options.
michael@0: #
michael@0: # .mozconfig is a shell script. To add an option to configure's
michael@0: #    command-line use the pre-defined function, ac_add_options,
michael@0: #
michael@0: #       ac_add_options  <configure-option> [<configure-option> ... ]
michael@0: #
michael@0: #    For example,
michael@0: #
michael@0: #       ac_add_options --with-pthreads --enable-debug
michael@0: #
michael@0: # ac_add_options can be called multiple times in .mozconfig.
michael@0: #    Each call adds more options to configure's command-line.
michael@0: 
michael@0: # Note: $_AUTOCONF_TOOLS_DIR must be defined in the script that includes this.
