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.
