 Sometimes there’s hard conflict between formulae, and it can’t be avoided or circumvented with `keg_only`.
 
-PolarSSL is a good [example](https://github.com/Homebrew/homebrew/blob/master/Library/Formula/polarssl.rb) formula for minor conflict.
+`mbedtls` is a good [example](https://github.com/Homebrew/homebrew/blob/master/Library/Formula/mbedtls.rb) formula for minor conflict.
 
-PolarSSL ship and compile a "Hello World" executable. This is obviously non-essential to PolarSSL’s functionality, and conflict with the popular GNU `hello` formula would be overkill, so we just remove it.
