Let's assume the retraining will be 2 or 3 orders of magnitude easier 
than switching from cvs to git, than that's doable.
Eclasses, ebuilds and documentation will be the real burden, but at this 
point it's better to discuss if the feature is wanted or not, then later 
wait for the volunteer(s) to actually do the work.

yep, that could be done, but since it's not trivial maybe better decide 
if it will be wasted or possibly accepted.


by the way eclasses from gentoo repo with PYTHON string inside are the 
following:

$ grep -c PYTHON *.eclass | grep -v :0$
distutils-r1.eclass:28
enlightenment.eclass:6
gnome-python-common-r1.eclass:2
kernel-2.eclass:2
mate.eclass:1
mozcoreconf-v4.eclass:3
python-any-r1.eclass:75
python-r1.eclass:107
python-single-r1.eclass:112
python-utils-r1.eclass:203
ros-catkin.eclass:40
