+--  > import Turtle
+--  > import Prelude hiding (FilePath)
+--
+--  This module re-exports the rest of the library and also re-exports useful
+--  modules from @base@:
+--
+--  "Turtle.Pattern" provides `Pattern`s, which are like more powerful regular
+--  expressions
+--
+--  "Turtle.Protected" provides `Protected` resources that are exception-safe
+--
+--  "Turtle.Shell" provides a streaming `Shell` abstraction for building
+--  exception-safe pipelines
+--
+--  "Turtle.Prelude" provides many useful derived utilities to get you started
+--  with basic shell-like programming within Haskell
+--
+--  "Control.Applicative" provides two classes:
+--
+--  * `Applicative`, which works with `Fold`, `Pattern`, `Protected`, and
+--    `Shell`
+--
+--  * `Alternative`, which works with `Pattern` and `Shell`
+--
+--  "Control.Monad" provides two classes:
+--
+--  * `Monad`, which works with `Pattern`, `Protected` and `Shell`
+--
+--  * `MonadPlus`, which works with `Pattern` and `Shell`
+--
+--  "Control.Monad.IO.Class" provides one class:
+--
+--  * `MonadIO`, which works with `Protected` and `Shell`
+--
+--  Additionally, you might also want to import "Control.Foldl" or
+--  "Control.Foldl.Text" qualified.
