Sorry if I was not sufficiently clear but that is not the case at all.

Current Cygwin package is python2 only from 2010 when python3 first came out.

You asked about the current Cygwin source package - that is all those answers 
refer to - and the logs relate to - nothing about the latest upstream package.

The Cygwin source package as distributed does not work with python3, it can not 
be easily upgraded to work with python3 using 2to3, and there is no way for us 
to rebuild it anyway, as it depends on some cygbuild "magic" not provided in the 
source package.

The latest version of the upstream package builds, installs, checks, and runs 
fine using minimal cygport and python3 cygclasses, as referred to in the 
scallywag links provided.

I am replacing the upstream man page provided, as it was written in POD, applies 
to the outdated 2010 release, and the latest upstream version's help has many 
more options, is more comprehensive, and was started with help2man.
