%description
Zlib is a general-purpose, patent-free, lossless data compression
library which is used by many different programs.

The library is available as 32-bit and 64-bit.

%define libdir64 /opt/freeware/lib64

Summary:	Header files and libraries for Zlib development
Group:		Development/Libraries
Requires:	%{name} = %{version}-%{release}

%description devel
The zlib-devel package contains the header files and libraries needed
to develop programs that use the zlib compression and decompression
library.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".
