+===========
+Quick Error
+===========
+
+:Status: production-ready
+:Documentation: http://tailhook.github.io/quick-error/
+
+A macro which makes error types pleasant to write.
+
+Features:
+
+* Define enum type with arbitrary parameters
+* Concise notation of ``Display`` and ``Error`` traits
+* Full control of ``Display`` and ``Error`` trait implementation
+* Any number of ``From`` traits
+* Support for all enum-variants ``Unit``, ``Tuple`` and ``Struct``
+
+Here is the comprehensive example:
+
+.. code-block:: rust
+
+    quick_error! {
+        #[derive(Debug)]
+        pub enum IoWrapper {
+            Io(err: io::Error) {
+                from()
+                display("I/O error: {}", err)
+                cause(err)
+            }
+            Other(descr: &'static str) {
+                display("Error {}", descr)
+            }
+            IoAt { place: &'static str, err: io::Error } {
+                cause(err)
+                display(me) -> ("io error at {}: {}", place, err)
+                from(s: String) -> {
+                    place: "some string",
+                    err: io::Error::new(io::ErrorKind::Other, s)
+                }
+            }
+            Discard {
+                from(&'static str)
+            }
+        }
+    }
