GV tap for homebrew
I did the bare minimum of work to get this functional, not promising any updates.
How do I install this formula?
brew install denismm/gv/gv
brew tap denismm/gv and then
brew install gv.
Or install via URL (which will not receive updates):
brew install https://raw.githubusercontent.com/denismm/homebrew-gv/master/Formula/gv%403.7.4.rb
If you have problems with ghostscript, try pinning this tap first so you'll get the version of ghostscript with x11 options.
man brew or check Homebrew's documentation.
