It works as expected for me =E2=80=94 thanks much for doing this

Specifically, it works in my macOS environment with homebrew-installed Pyth=
on3.

When I test with XCode-installed Python3, I run into what seems to be a
general known issue with trying to run any Python code with that =E2=80=94 =
which is
apparently due to the XCode installer not installing any root SSL certs; so
with that XCode Python3, any Python code that has, e.g., urllib.request.url=
open()
calls ends up running into this error:

  SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get
  local issuer certificate (_ssl.c:1056 cafile

But it seems that Apple doesn=E2=80=99t consider it a bug and the solution =
they
suggest is to use the 'request' library rather than urllib =E2=80=94

=2E..or else to change the code to import certifi and change all the
urllib.request.urlopen() calls to include a cafile arg, like this:

  urllib.request.urlopen(ghPrefix + "manifest.txt", cafile=3Dcertifi.where(=
))

Not sure if that=E2=80=99d be a useful solution in practice, if it=E2=80=99=
d also require
Bikeshed users to pip install certifi =E2=80=94 because I think they=E2=80=
=99d need to have
root perms to do that.
