%description
The 'zlib' compression library provides in-memory compression and
decompression functions, including integrity checks of the
uncompressed data. This version of the library supports only one
compression method (deflation) but other algorithms may be added later
and will have the same stream interface.

This package contains the cross version for Win32.

%description -l pl.UTF-8
Biblioteka zlib udostępnia podprogramy do kompresji i dekompresji w
pamięci operacyjnej włącznie ze sprawdzaniem integralności w trakcie
dekompresji. Ta wersja biblioteki udostępnia tylko jedną metodę
kompresji o nazwie deflation niemniej inne algorytmy mogą być
dodawane udostępniając taki sam interfejs funkcji operujących na
strumieniu danych.

Ten pakiet zawiera wersję skrośną dla Win32.
