Example: build-formula.sh -f Formula/aws-sam-cli.rb
Required:
-f Formula file to build
Optional:
-h Print this usage help
-u Use existing tap instead of untapping and retapping
-l Dynamically sets the TAP to the first git remote found that is not the official aws tap
-t Specify a sepcific tap i.e. `-t bwagner5/tap`
