WARNING: I use this tap for adding HEAD url and a few options. Because I install from source, bottle and tar files are probably outdated. So this tap will be useful ONLY if you are installing development/HEAD version.
brew install muhammedzakir/personal/<formula>
Or brew tap muhammedzakir/personal and then brew install <formula>.
Or install via URL (which will not receive updates):
brew install https://raw.githubusercontent.com/MuhammedZakir/homebrew-personal/master/Formula/<formula>.rb
brew help, man brew or check Homebrew's documentation.
