-zlib 1.0.4 is a general purpose data compression library. All the code
-is reentrant (thread safe). The data format used by the zlib library
-is described by RFCs (Request for Comments) 1950 to 1952 in the files
-ftp://ds.internic.net/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate
-format) and rfc1952.txt (gzip format). These documents are also available in
-other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
-
-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.
-
-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.
-
-Questions about zlib should be sent to <zlib@quest.jpl.nasa.gov> or,
-if this fails, to the addresses given below in the Copyright section.
-The zlib home page is http://quest.jpl.nasa.gov/zlib/
-
-The changes made in version 1.0.4 are documented in the file ChangeLog.
-The main changes since 1.0.3 are:
-
-- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
- bit, so the decompressor could decompress all the correct data but went
- on to attempt decompressing extra garbage data. This affected minigzip too.
-- zlibVersion and gzerror return const char* (needed for DLL)
-- port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno)
-
-
-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*
-
-
-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 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). The compiler bug has been reported to SGI.
-
-- 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.
-
-- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
- and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
- For help on building a zlib DLL, contact Alessandro Iacopetti
- <iaco@email.alessandria.alpcom.it> http://lisa.unial.it/iaco ,
- or contact Brad Clarke <bclarke@cyberus.ca>.
-
-- gzdopen is not supported on RISCOS
