+    (description
+     "Turtle is a reimplementation of the Unix command line environment in
+Haskell so that you can use Haskell as both a shell and a scripting
+language.  Features include:
+
+@itemize
+@item Batteries included: Command an extended suite of predefined utilities.
+@item Interoperability: You can still run external shell commands.
+@item Portability: Works on Windows, OS X, and Linux.
+@item Exception safety: Safely acquire and release resources.
+@item Streaming: Transform or fold command output in constant space.
+@item Patterns: Use typed regular expressions that can parse structured values.
+@item Formatting: Type-safe printf-style text formatting.
+@item Modern: Supports text and system-filepath.
+@end itemize
+
+Read \"Turtle.Tutorial\" for a detailed tutorial or \"Turtle.Prelude\" for a
+quick-start guide.  Turtle is designed to be beginner-friendly, but as a
+result lacks certain features, like tracing commands.  If you feel comfortable
+using turtle then you should also check out the Shelly library which provides
+similar functionality.")
