Hi, we would like to use Python 3 on the default installation instead of Python 2 on Fedora 22.
From that perspective, your package is considered as IMPORTANT - that means, is has to be updated to Python 3, for our intention come true.
The goal here is, that at least for F22 you should provide python3- prefixed subpackage.
Please, help use update to Python 3 flawlessly.
Check if upstream already support Python 3, if yes, use it and add te support to the package.
If upstream doesn't support Python 3 yet, encourage it to do so by sending patches and offering your help.
When upstream is dead or unwilling to support Python 3, you'll need to patch this package on Fedora level. Try to avoid this as much as you can, but use it, if it's the last option.
Chances are, that you ARE the upstream. In that case, everything is easier, just do it yourself.
There is a table on wiki, that should list your package. Chances are, that you can see an upstream link that covers the problem. Anyway, please update the table with information you know.
I offer my help with this task, so if you have no idea, how to work on this, or it is just not your priority, don't hesitate to ask for help.
(As you've already realized, this is a bulk text, so if something is not quite exact about your package, sorry for that, just ask)
Python3 support is just build for rawhide
