| 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. | |
