+// I, Mathias Panzenböck, place this file hereby into the public domain. Use
+// it at your own risk for whatever you like. In case there are
+// jurisdictions that don't support putting things in the public domain you
+// can also consider it to be "dual licensed" under the BSD, MIT and Apache
+// licenses, if you want to. This code is trivial anyway. Consider it an
+// example on how to get the endian conversion functions on different
+// platforms.
