# brew-bundle.rb
#
# Usage: brew bundle [path]
#
# Looks for a Brewfile and runs each line as a brew command.
#
# brew bundle # Looks for "./Brewfile"
# brew bundle path/to/dir # Looks for "path/to/dir/Brewfile"
# brew bundle path/to/file # Looks for "path/to/file"
#
# For example, given a Brewfile with the following contents:
# tap foo/bar
# install spark
#
# Running `brew bundle` will run the commands `brew tap foo/bar`
# and `brew install spark`.
