A keg for homebrew-installable GIS recipes.
brew tap walker/geokeg
Geogig is a GIS version control system that works on a git-like command model. There are some fundamental differences though because of the way GIS files work, so it's not a 1:1 match.
You will need JRE 1.8+, the Java 8 runtime environment. You can install it with homebrew with the command brew cask install java.
brew install walker/geokeg/geogig
