| # Zlib | |
| Zlib ([RFC 1950](https://www.ietf.org/rfc/rfc1950.txt)) is a thin wrapper | |
| around raw deflate (RFC 1951). Zlib is similar to gzip (RFC 1952), but with a | |
| different wire format and checksum algorithm. | |
| Zlib is used by the ELF executable and PNG image file formats. | |
| TODO: a worked example. |
