 If you want to run a command written in Ruby like `rake`, `rails`, `bundle`, `rspec`, and so on, you can use `rdbg -c` option.

 Examples:

 * `rdbg -c -- bundle exec ruby foo.rb`
 * `rdbg -c -- bundle exec rake test`
-* `rdbg -c -- ruby target.rb` is same as `rdbg target.rb`
+* `rdbg -c -- ruby target.rb` is the same as `rdbg target.rb`
 
-NOTE: `--` is needed to separate the command line options for `rdbg` and invoking command. For example, `rdbg -c rake -T` is recognized like `rdbg -c -T -- rake`. It should be `rdbg -c -- rake -T`.
