+TinyEndian
+==========
+
+![](https://travis-ci.org/dlang-community/tinyendian.svg?branch=master) ![](https://img.shields.io/dub/v/tinyendian.svg)
+
+Introduction
+------------
+
+TinyEndian is a minimal endianness library for the D programming
+language. It has no external dependencies, it only needs a D compiler
+and Phobos (standard library). TinyEndian doesn't allocate memory and is
+fully `@nogc` to allow use in high-performance code.
+
+The API is not stable and may change in the future.
+
+Features
+--------
+
+-   Swap byte order of 2- or 4-byte elements in an array in place.
+-   Read a UTF-8, UTF-16 or UTF-32 buffer, determine its endianness
+    using a UTF byte-order-mark and convert it to system endianness in
+    place.
+-   No external dependencies.
+-   pure, nothrow and @nogc.

+
+Usage
+-----
+
+Assuming you use [dub](http://code.dlang.org/about), add this line:
+
+    "tinyendian": { "version" : "~>0.2.0" }
+
+to the `"dependencies"` in your project's `dub.json`.
+
+If you don't use dub, you can directly copy the `source/tinyendian.d`
+file into your project.
+
+TinyEndian requires DMD 2.067 or better.
