; LZ4 data decompressor for Apple II

|

; "LZ4 unpacker in 143 bytes (6502 version) (2013)"

; This is that code, but with comments and labels added for clarity.

; I also found a bug when decoding with runs of multiples of 256

; which has since been fixed upstream.

; + The literal bytes follow. There may be zero of them
|

; At end you have 4 byte end-of-block marker (all zeros?) then
