Tired of adding # frozen_string_literals: true to every file in your project or
running rubocop -A to make it do that for you? What if I told you that you can
just add a single gem to your project and activate this option for the project's
files automatically (without enabling it globally)?

Freezolite is a gem that turns the frozen_string_literal compile option on only
for the specified files. Thus it's like running Ruby
with --enable=frozen-string-literal but only for the files you own.
