Bug Summary

Can't pass a String either by-value or by borrow to about. Error message:

error[E0277]: the trait bound `&str: std::convert::From<&std::string::String>` is not satisfied
  --> src/main.rs:12:34

   |
   = note: required because of the requirements on the impl of `std::convert::Into<&str>` for `&std::string::String`

You can either call as_str:

let matches = App::new(NAME).about(description.as_str()).get_matches();

or use &* (which is now suggested by rustc):

let matches = App::new(NAME).about(&*description).get_matches();

I'm trying to understand why the API use Into<&str> in the first place. Do you have any references ? @JD557
