| // zlib's configuration prefix and checksum suffix wrapped around that. |
| // |
| // A zlib.decoder basically becomes a deflate.decoder. This is useful when the |
| // caller might want to choose between the two related-but-slightly-different |
| // formats at run time but would rather not allocate two separate decoders. |
