I'm still fought whether docs should be in the C module or in the .rst.
I'd prefer the first because DRY, but writing multiline strings in C
really sucks.
Per https://docs.python.org/3/library/optparse.html
> Deprecated since version 3.2: The optparse module is deprecated and

The sandbox directory was there to test issues before we had full test
coverage and to try quick and dirty Python snippets before moving them to
the examples directory, sending them to mailing list or copying them to
the docs. Almost anything that was in sandbox is now in the examples
directory or has been refactored into a full test, or is so old that is
of no use anymore. So, adieu sandbox.
distutils is not recommended for use and unnecessary for modern Python
environments. Use only setuptools instead. From
https://docs.python.org/3/library/distutils.html:
> Most Python users will not want to use this module directly, but
> instead use the cross-version tools maintained by the Python Packaging
> Authority. In particular, setuptools is an enhanced alternative to
> distutils ...
>
> The recommended pip installer runs all setup.py scripts with
> setuptools, even if the script itself only imports distutils. Refer to
> the Python Packaging User Guide for more information.
The FreeBSD-related condition which enables custom round() implementation is incorrect: one must include <sys/param.h> to get __FreeBSD_version value, and since it's not included here, the check succeeds while it shouldn't. Before it worked somehow, but since python 3.7 it results in conflicting declarations of round(). The condition is also no longer needed since FreeBSD 5.3 is unsupported for 12 years.
The errcodes.txt file contains all the errors for the currently
maintained server versions. There is only one error code missing,
probably unused, but adding it back anyway to keep the errcode module
unchanged.
