       This code is no longer maintained. We recommend using the Go mmdbwriter package
       <https://github.com/maxmind/mmdbwriter> to write MMDB files.

       This distribution contains the code necessary to write MaxMind DB database files
       <http://maxmind.github.io/MaxMind-DB/>. See MaxMind::DB::Writer::Tree for API docs.

       If you're running into install errors under Mac OS X, you may need to force a build of the 64 bit binary.
       For example, if you're installing via "cpanm":

           ARCHFLAGS="-arch x86_64" cpanm MaxMind::DB::Writer

       This distribution does not currently work on Windows. Reasonable patches for Windows support are very
       welcome. You will probably need to start by making Math::Int128 work on Windows, since we use that
       module's C API for dealing with 128-bit integers to represent IPv6 addresses numerically.
