+zlib 1.0 is a general purpose data compression library.
+All the code is reentrant (thread safe).
+
+The data format used by the zlib library is described in the
+files zlib-3.2.doc, deflate-1.2.doc and gzip-4.2.doc, available
+in ftp://ftp.uu.net/pub/archiving/zip/doc
 
 All functions of the compression library are documented in the file
 zlib.h. A usage example of the library is given in the file example.c
 which also tests that the library is working correctly. Another
-example is given in the file minigzip.c. The compression library itself
-is composed of all source files except example.c and minigzip.c.
+example is given in the file minigzip.c.
 
-To compile all files and run the test program, follow the instructions
-given at the top of Makefile. In short "make test; make install"
-should work for most machines.  For MSDOS, use one of the special
-makefiles such as Makefile.msc; for VMS, use Make_vms.com or descrip.mms.
+To compile all files and run the test program, just type: make test
+(For MSDOS, use one of the special makefiles such as Makefile.msc;
+for VMS, use Make_vms.com or descrip.mms.)
+To install the zlib library (libz.a) in /usr/local/lib, type: make install
+To install in a different directory, use for example:
+  make install prefix=$HOME
+This will install in $HOME/lib instead of /usr/local/lib.

 The changes made in version 1.0 are documented in the file ChangeLog.
 The main changes since 0.95 are:
-- allow preset dictionary shared between compressor and decompressor
 - allow compression level 0 (no compression)
 - add deflateParams in zlib.h: allow dynamic change of compression level
   and compression strategy.
 - test large buffers and deflateParams in example.c
-- add optional "configure" to build zlib as a shared library
-- suppress Makefile.qnx, use configure instead
-- fixes for 64-bit systems (needed for Alpha and Cray)
 - declare Z_DEFLATED in zlib.h (possible parameter for deflateInit2)
+- fixes for 64-bit systems (needed for Alpha and Cray)
 - always return Z_BUF_ERROR when deflate() has nothing to do
-- deflateInit and inflateInit are now macros to allow version checking
-- prefix all global functions and types with z_ with -DZ_PREFIX
-- fix some very unlikely race conditions in multi-threaded environment
+- fix some very unlikely race conditions.
 - several minor fixes for better portability
 - free in reverse order of allocation to help memory manager
-- use zlib-1.0/* instead of zlib/* inside the tar.gz
-- make zlib warning-free with "gcc -O3 -Wall -Wwrite-strings -Wpointer-arith
-  -Wconversion -Wstrict-prototypes -Wmissing-prototypes"
-- allow gzread on concatenated .gz files
-- deflateEnd now returns Z_DATA_ERROR if it was premature
-- deflate is finally (?) fully deterministic
 
 Notes for some targets:
 
-- For Turbo C the small model is supported only with reduced performance to
-  avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
+- For MSDOS, the small and medium models have been tested only with
+  Microsoft C.  (This should work for Borland C also, but I don't have
+  a Borland compiler to test with.) The small model was tested with
+  Turbo C but only with reduced performance to avoid any far
+  allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
+
+  MS Visual C++1.5 in far model gives:
+     warning C4746: 'z_errmsg' : unsized array treated as '__far'
+     warning C4746: 'inflate_mask' : unsized array treated as  '__far'
+  Ignore those warnings.
 
 - For 64-bit Iris, deflate.c must be compiled without any optimization.
   With -O, one libpng test fails. The test works in 32 bit mode (with the
   -32 compiler flag).
 
-- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1   
-  it works when compiled with cc.
-
-- zlib doesn't work on HP-UX 9.05 with one cc compiler (the one not
-  accepting the -O option). It works with the other cc compiler.

-A Perl interface to zlib written by Paul Marquess <pmarquess@bfsec.bt.co.uk>
-is in the CPAN (Comprehensive Perl Archive Network) sites, such as:
-ftp://ftp.cis.ufl.edu/pub/perl/CPAN/modules/by-module/Compress/Compress-Zlib*
-
-Acknowledgments:
-
-  The deflate format used by zlib was defined by Phil Katz. The deflate
-  and zlib specifications were written by Peter Deutsch. Thanks to all the
-  people who reported problems and suggested various improvements in zlib;
-  they are too numerous to cite here.
