### Overriding global customization

Pry.config settings apply to all Pry instances, but some values can be overridden for a specific instance. The values that can be overridden are: `input`, `output`, `print`, `exception_handler`, `prompt`, and `hooks`. To override a given value, pass a new value as a hashed option for the method that initiates Pry.

Example: Overriding a global default at instantiation

```ruby
Pry.config.input = File.open("test.rb")

# Use a string-io for this specific instance.
