-.TH ZLIB 3 "15 Jan 2017"
-.SH NAME
-zlib \- compression/decompression library
-.SH SYNOPSIS
-[see
-.I zlib.h
-for full description]
-.SH DESCRIPTION
-The
-.I zlib
-library is a general purpose data compression library.
-The code is thread safe, assuming that the standard library functions
-used are thread safe, such as memory allocation routines.
-It 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
-with the same stream interface.
-.LP
-Compression can be done in a single step if the buffers are large enough
-or can be done by repeated calls of the compression function.
-In the latter case,
-the application must provide more input and/or consume the output
-(providing more output space) before each call.
-.LP
-The library also supports reading and writing files in
-.IR gzip (1)
-(.gz) format
-with an interface similar to that of stdio.
-.LP
-The library does not install any signal handler.
-The decoder checks the consistency of the compressed data,
-so the library should never crash even in the case of corrupted input.
-.LP
-All functions of the compression library are documented in the file
-.IR zlib.h .
-The distribution source includes examples of use of the library
-in the files
-.I test/example.c
-and
-.IR test/minigzip.c,
-as well as other examples in the
-.IR examples/
-directory.
-.LP
-Changes to this version are documented in the file
-.I ChangeLog
-that accompanies the source.
-.LP
-.I zlib
-is built in to many languages and operating systems, including but not limited to
-Java, Python, .NET, PHP, Perl, Ruby, Swift, and Go.
-.LP
-An experimental package to read and write files in the .zip format,
-written on top of
-.I zlib
-by Gilles Vollant (info@winimage.com),
-is available at:
-.IP
-http://www.winimage.com/zLibDll/minizip.html
-and also in the
-.I contrib/minizip
-directory of the main
-.I zlib
-source distribution.
-.SH "SEE ALSO"
-The
-.I zlib
-web site can be found at:
-.IP

-.LP
-The data format used by the
-.I zlib
-library is described by RFC
-(Request for Comments) 1950 to 1952 in the files:
-.IP
-http://tools.ietf.org/html/rfc1950 (for the zlib header and trailer format)
-.br
-http://tools.ietf.org/html/rfc1951 (for the deflate compressed data format)
-.br
-http://tools.ietf.org/html/rfc1952 (for the gzip header and trailer format)
-.LP
-Mark Nelson wrote an article about
-.I zlib
-for the Jan. 1997 issue of  Dr. Dobb's Journal;
-a copy of the article is available at:

-.SH "REPORTING PROBLEMS"
-Before reporting a problem,
-please check the
-.I zlib
-web site to verify that you have the latest version of
-.IR zlib ;
-otherwise,
-obtain the latest version and see if the problem still exists.
-Please read the
-.I zlib
-FAQ at:
-.IP
-http://zlib.net/zlib_faq.html
-.LP
-before asking for help.
-Send questions and/or comments to zlib@gzip.org,
-or (for the Windows DLL version) to Gilles Vollant (info@winimage.com).
