Branch project for KDE:Frameworks5
This project contains Plasma 5 packages that don't conflict with kdebase4-workspace or the corresponding KDE4 applications' packages, so can be installed side-by-side with KDE4 (they install to /opt/kf5).
Install plasma5-session to be able to select Plasma 5 on your Login Screen.
Please note that you also need the repos KDE:Frameworks5 and KDE:Qt5 for neccessary packages!
This project only contains versions of those packages from there that conflict with KDE4.
Exception: The Tumbleweed repo is built against plain Tumbleweed, no additional repo needed there.
You should probably give this repo a higher priority (= lower priority number) than KDE:Frameworks5 and the standard repos, especially on Tumbleweed, to make sure the packages from here are preferred (by "zypper dup" in particular).
