    # Code match-and-transform procedure.
    #
    # This is useful to transform human readable code examples
    # into proper exectuable code. For example, say you want to
    # run shell code, but want to make if look like typical
    # shelle examples:
    #
    #    $ cp fixture/a.rb fixture/b.rb
    #
    # You can use a transform to convert lines starting with '$'
    # into executable Ruby using #system.
    #
    #    system('cp fixture/a.rb fixture/b.rb')
    #
