Hi Nick,

I've finally put some short guidance to:

https://wiki.centos.org/SpecialInterestGroup/SCLo#head-b408f06ad89fd3a67686f755eafac7ce310ee081

I think that by this mail you basically did the step "Propose adding a 
new SCL on the mailing list", so now we should agree on the naming and 
SCL purpose.

 From my PoV, the last proposal of having "sclo-python3" with "always 
latest major Python 3" looks good to me, I'll also ask python maint team 
for their opinion, but if nobody is against here, we can go with this 
approach.

The next step will be you (or the person who is going to build the 
packages) becoming a SIG member 
(https://wiki.centos.org/HowTos/CommunityBuildSystem) and then we need 
to request build tags in the cbs.centos.org 
(https://wiki.centos.org/SpecialInterestGroup/SCLo#head-4ce81a8b651b8a1217a0c97f757e0eab869bea48).

Whether you'll find https://github.com/sclorg-distgit useful for 
development, or it will be used only for adding sources after build, 
it's up to you..

Let me know if you have any further questions..
