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

# Note: $_AUTOCONF_TOOLS_DIR must be defined in the script that includes this.
