  Usage: mt2rspec [--rails] [--mocha] source_file [target_file]

  Reads source_file, writes target_file. If target_file is omitted,
  its location will be inferred. For example, test/fruit/banana_test.rb
  implies spec/fruit/banana_spec.rb. If the target directory doesn't
  exist, it will be created.

  Options:
EOS
OPT_MOCHA = 
'Convert mocha to rspec-mocks. (Experimental)'
OPT_RAILS = 
<<~EOS.tr("\n", ' ').freeze
  Requires rails_helper instead of spec_helper.
  Passes :type metadatum to RSpec.describe.
