a "better" be "alias" for bundle exec, prioritizing local binstubs

be.rb

#!/usr/bin/env ruby

# Smarter be for ruby projects that prioritizes local project binstubs
# - uses zsh when needed, assuming MacOS Catalina or later
# - save on your path
# - drop the .rb
# - chmod +x
# - always type `be <command>` and the right thing should happen
#
# - inspired by Justin Searls (@searls)
