 /*!
 
-The `io` module contains basic input and output routines.
-
-A quick summary:
-
-## `Reader` and `Writer` traits
-
-These traits define the minimal set of methods that anything that can do
-input and output should implement.
-
-## `ReaderUtil` and `WriterUtil` traits
-
-Richer methods that allow you to do more. `Reader` only lets you read a certain
-number of bytes into a buffer, while `ReaderUtil` allows you to read a whole
-line, for example.
-
-Generally, these richer methods are probably the ones you want to actually
-use in day-to-day Rust.
-
-Furthermore, because there is an implementation of `ReaderUtil` for
-`<T: Reader>`, when your input or output code implements `Reader`, you get
-all of these methods for free.
-
-## `print` and `println`
-
-These very useful functions are defined here. You generally don't need to
-import them, though, as the prelude already does.
-
-## `stdin`, `stdout`, and `stderr`
-
-These functions return references to the classic three file descriptors. They
-implement `Reader` and `Writer`, where appropriate.
