  55 The build configuration is determined by named arguments and CC/FC
  56 environment variables.  The script chooses matching build options from
  57 the list of available options displayed by the default configure script,
  58 so compatible builds can be started that don't depend on the numbering
  59 provided by a particular version of WRF.  The CC/FC variables should
  60 be in the option list title in arch/configure_new.defaults.  This means
  61 FC=PGI will work but not FC=pgf90.  Future versions of this script may
  62 allow for better selection of compilers and path substitution.  By default,
  63 the script will succeed only if exactly one option matches.  You can refine
  64 the selection by providing a regex with the -r option.  The -1 option will
  65 use the first match it encounters and not error out if there are more." >&2
