[likewise snipped lots of stuff]

Thanks.  Given that, I went ahead and created a Feature page for this:
https://fedoraproject.org/wiki/Features/Python3F13

So far it's mostly just a restatement of my post, though I've started
fleshing out some sections e.g. "how to test".  I've assumed the naming
convention from my post "python3" for the srpm, and for the symlink to
the binary.  

Feel free to dive in and edit.  I marked myself as owner of the feature
as I know I'm going to be able to devote a big chunk of time to this.
Hope that's OK.

We now have 3 competing srpms for Python 3:
(i) the one from ivazquez:

("python3000")

(ii) the one by Andrew McNabb:
https://bugzilla.redhat.com/show_bug.cgi?id=526126 (named "python3")

(iii) and the one I did, also named "python3":

I'm assuming ivazquez is seeing these emails (I _think_ he said he'd
seen it on IRC earlier today), and I added a link to my email to the
review bug above so hopefully Andrew is seeing this.

I hope to have a look at the commonality/differences between the 3
efforts tomorrow.  I think "python3" is a better name (if nothing else,
it's shorter to type!).

I'd like it if the eventually python 3 specfile could resemble the
python 2 specfile so that we can meaningfully look at the textual diffs
between them (but it may be necessary to clean up the python specfile to
achieve this!  I'll try to have a look at the merge-review)

Thanks for the feedback; hope this all sounds sane
