+Native LZO1X implementation in Golang
+
+This code has been written using the original LZO1X source code as a reference,
+to study and understand the algorithms. Both the LZO1X-1 and LZO1X-999
+algorithms are implemented. These are the most popular of the whole LZO suite
+of algorithms.
+
+Being a straightforward port of the original source code, it shares the same
+license (GPLv2) as I can't possibly claim any copyright on it.
+
+I plan to eventually reimplement LZO1X-1 from scratch. At that point, I will be
+also changing license.
