libz/1.2.1100+2

General-purpose lossless data compression C library

zlib is a general-purpose lossless data compression C library. The data format
used by the library is described by RFCs 1950, 1951, and 1952 (zlib, deflate,
and gzip formats, respectively). For more information see:

https://www.zlib.net/

This package contains the original libz library source code overlaid with the
build2-based build system and packaged for the build2 package manager (bpkg).

See the INSTALL file for the prerequisites and installation instructions.
