  16 -----------
  17
  18 ``BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS`` is an boolean configuration macro
  19 regulating library's internal use of preprocessed headers. When defined, it
  20 instructs the MPL to discard the pre-generated headers found in
  21 ``boost/mpl/aux_/preprocessed`` directory and use `preprocessor
  22 metaprogramming`__ techniques to generate the necessary versions of the
  23 library components on the fly.
  24
  25 In this implementation of the library, the macro is not defined by default.
  26 To change the default configuration, define
  27 ``BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS`` before  including any library
  28 header.
