  STDERR.puts <<EndOfHelp
Usage: #{$0} submission.rb specfile.rb

Creates an autograder of the RspecGrader subclass (which evaluates student
code based solely on RSpec output) and grades the submission.rb file with it.

For example, try these, where PREFIX=rag/spec/fixtures:

#{$0} $PREFIX/correct_example.rb $PREFIX/correct_example.spec.rb
#{$0} $PREFIX/example_with_syntax_error.rb $PREFIX/correct_example.spec.rb
#{$0} $PREFIX/example_with_runtime_exception.rb $PREFIX/correct_example.spec.rb
