<h3> A Bit Of History </h3>
10
You'll find <a href="http://www.gzip.org">gzip</a> using the same compression
11
that was written by Jean-loup <a href="http://gailly.net">Gailly</a>
12
for the <a href="http://www.info-zip.org">Info-Zip</a> Group
13
whose <a href="http://www.info-zip.org/pub/infozip/Zip.html">Zip</a>
14
program is compatible with msdos PKZIP program from
15
<a href="http://www.pkware.com">PK Ware</a>. Then, in collaboration
16
with <a href="http://www.alumni.caltech.edu/~madler">Mark Adler</a>
17
he wrote the <a href="http://www.gzip.org/zlib">zlib</a>
18
compression library which was later standardized in the
19
<a href="ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html">
21
<a href="http://www.ietf.org/rfc/rfc1950.txt">RFC 1950</a>
22
<a href="ftp://ftp.uu.net/graphics/png/documents/zlib/rfc-zlib.html.Z">
24
<a href="http://www.ietf.org/rfc/rfc1951.txt">RFC 1951</a>
25
<a href="ftp://ftp.uu.net/graphics/png/documents/zlib/rfc-deflate.html.Z">
26
deflate 1.3</a> and
27
<a href="http://www.ietf.org/rfc/rfc1952.txt">RFC 1952</a>
28
<a href="ftp://ftp.uu.net/graphics/png/documents/zlib/rfc-gzip.html">
29
gzip 4.3</a>. The free algorithm can be found in lots of places
30
today including PPP packet compression and PNG picture compression.
34
<h3> Installation </h3>
37
The installation is from the source .tar.gz tarball does follow
38
the simple gnu style: type <tt>''configure && make install''</tt>
39
in the unpacked directory. This will actually perform the usual
40
sequence of <tt>''configure && make && make install''</tt>. The
41
use of <tt>''make rpm''</tt> will make rpms based on your system
42
setup, and using a decent mingw32 compiler (e.g. the crossgcc
43
from <a href="http://libsdl.org/Xmingw32">libsdl.org/Xmingw32</a>)
44
will allow you to create windows dlls using a gnu development
45
environment. MSVC and Borland support (Make-)files should be
46
easy to be derived from the <a href="Makefile.am">Makefile.am</a>
53
The library was developed by
54
<a href="mailto:guidod@gmx.de?subject=zziplib">
55
Guido Draheim </a> based on the library
56
<a href="http://freshmeat.net/appindex/1999/08/02/933593367.html">
58
by <a href="mailto:too@iki.fi"> Tomi Ollila </a> (many thanks
59
for his support of the zziplib project). He has provided
60
a good deal of testing rounds and very helpful comments.
61
It may be assumed that this library supersedes
62
<a href="http://www.iki.fi/too/sw/zip08x.readme">
63
<tt>zip08x</tt></a>, and in April 2002, he
64
has even given up copyright restrictions coming from zip08x
65
and changed the <a href="http://www.iki.fi/too/sw/zip08x.readme">zip08x</a>
66
readme to point to <a href="http://zziplib.sf.net">zziplib</a>.
67
Anyone who wants to contribute in accessing zip-archives
68
with the zlib-library is hereby kindly invited to send us
69
comments and sourcecode.

<a href="http://pobox.com/~newt">[3]</a> package originally developed

by the <a href="http://www.info-zip.org">Info-Zip</a> Group

As of late, the pkware appnote.txt has been revised into a whitepaper
85
<a href="http://www.pkware.com/products/enterprise/white_papers/appnote.html">
86
"APPNOTE.TXT - .ZIP File Format Specification"</a>.
87
Be also aware of other zzip like projects, e.g.
88
<a href="http://zipios.sourceforge.net">zipios++</a> that
89
mangles zip access into C++ iostream facilities.
