As stated in the announcement, the page http://www.swox.se/gmp/gmp3.1.html,
in the NEWS file and mpfr/README file the integration of mpfr with GMP is
in no way completed. It is an experimental part of GMP.

Being experimental the option was not included in the GMP manual.
Perhaps it should have been. The option is documented in the locations
listed above.

The original mpfr documentation from the mpfr-0.4 distribution was to
be included in the mpfr directory but unfortunately this was forgotten
(by me, sorry). To get the documentation you have to download the
mpfr-0.4 distribution for the texinfo file or download the dvi file

Again, sorry about this,
