Merge forked repositories with barbushin/dater

[barbushin]

Hi guys,

barbushin/dater has a big refactoting, and I see that there are 5 forks, that are not so up to date. I'm just worried that old version code usage is not compatible with new code, so I want to ask everybody to merge with barbushin/dater repository. It's very easy:

git remote add upstream https://github.com/barbushin/dater.git
git fetch upstream
git merge upstream/master
git pull upstream/master
