    Official GNU MPFR website:

      https://www.mpfr.org/

    NOTE: At the time of the release 4.1.0, the MPFR repository is hosted at
    InriaForge, but it will need to migrate since InriaForge will shut down in
    December 2020. Please go to https://www.mpfr.org/ for the current status.
    What follows remains valid until the migration is done.

    You can get the latest source code by Subversion at InriaForge:

      svn checkout svn://scm.gforge.inria.fr/svn/mpfr/trunk mpfr

    or

      svn checkout https://scm.gforge.inria.fr/svn/mpfr/trunk mpfr

    (the last argument can be any directory name). You can use

      svn ls svn://scm.gforge.inria.fr/svn/mpfr/branches
      svn ls svn://scm.gforge.inria.fr/svn/mpfr/tags

    to get the list of branches or tags (releases), then checkout a
    particular branch or tag instead of the trunk. Alternatively, you
    can now use the "https:" scheme (a.k.a. DAV) instead of "svn:".
    For more information about Subversion, please see:

      * http://svnbook.red-bean.com/ (the official Subversion book);
      * https://gcc.gnu.org/wiki/SvnHelp (written for GCC developers,
        but interesting general information can be found there);
      * http://subversion.apache.org/faq.html (the Subversion FAQ).

    Subversion users should read the file "doc/README.dev" (in the
    source tree).
