-// Package s2 implements the S2 compression format.
-//
-// S2 is an extension of Snappy. Similar to Snappy S2 is aimed for high throughput,
-// which is why it features concurrent compression for bigger payloads.
-//
-// Decoding is compatible with Snappy compressed content,
-// but content compressed with S2 cannot be decompressed by Snappy.
-//
-// For more information on Snappy/S2 differences see README in: https://github.com/klauspost/compress/tree/master/s2
-//
-// There are actually two S2 formats: block and stream. They are related,
-// but different: trying to decompress block-compressed data as a S2 stream
-// will fail, and vice versa. The block format is the Decode and Encode
-// functions and the stream format is the Reader and Writer types.
-//
-// A "better" compression option is available. This will trade some compression
-// speed
-//
-// The block format, the more common case, is used when the complete size (the
-// number of bytes) of the original data is known upfront, at the time
-// compression starts. The stream format, also known as the framing format, is
-// for when that isn't always true.
-//
-// Blocks to not offer much data protection, so it is up to you to
-// add data validation of decompressed blocks.
-//
-// Streams perform CRC validation of the decompressed data.
-// Stream compression will also be performed on multiple CPU cores concurrently
-// significantly improving throughput.

-Each encoded block begins with the varint-encoded length of the decoded data,
-followed by a sequence of chunks. Chunks begin and end on byte boundaries. The
-first byte of each chunk is broken into its 2 least and 6 most significant bits
-called l and m: l ranges in [0, 4) and m ranges in [0, 64). l is the chunk tag.
-Zero means a literal tag. All other values mean a copy tag.
-
-For literal tags:
-  - If m < 60, the next 1 + m bytes are literal bytes.
-  - Otherwise, let n be the little-endian unsigned integer denoted by the next
-    m - 59 bytes. The next 1 + n bytes after that are literal bytes.
-
-For copy tags, length bytes are copied from offset bytes ago, in the style of
-Lempel-Ziv compression algorithms. In particular:
-  - For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12).
-    The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10
-    of the offset. The next byte is bits 0-7 of the offset.
-  - For l == 2, the offset ranges in [0, 1<<16) and the length in [1, 65).
-    The length is 1 + m. The offset is the little-endian unsigned integer
-    denoted by the next 2 bytes.
-  - For l == 3, the offset ranges in [0, 1<<32) and the length in
-    [1, 65). The length is 1 + m. The offset is the little-endian unsigned
-    integer denoted by the next 4 bytes.
