-This is a patched version of zlib modified to use
-Pentium-optimized assembly code in the deflation algorithm. The files
-changed/added by this patch are:
-
-README.586
-match.S
-
-The effectiveness of these modifications is a bit marginal, as the the
-program's bottleneck seems to be mostly L1-cache contention, for which
-there is no real way to work around without rewriting the basic
-algorithm. The speedup on average is around 5-10% (which is generally
-less than the amount of variance between subsequent executions).
-However, when used at level 9 compression, the cache contention can
-drop enough for the assembly version to achieve 10-20% speedup (and
-sometimes more, depending on the amount of overall redundancy in the
-files). Even here, though, cache contention can still be the limiting
-factor, depending on the nature of the program using the zlib library.
-This may also mean that better improvements will be seen on a Pentium
-with MMX, which suffers much less from L1-cache contention, but I have
-not yet verified this.
-
-Note that this code has been tailored for the Pentium in particular,
-and will not perform well on the Pentium Pro (due to the use of a
-partial register in the inner loop).
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)

- * Two optimization notes on the choice of instructions:
- *
- * The first instruction uses a 16-bit address, which costs an extra,
- * unpairable cycle. This is cheaper than doing a 32-bit access and
- * zeroing the high word, due to the 3-cycle misalignment penalty which
- * would occur half the time. This also turns out to be cheaper than
- * doing two separate 8-bit accesses, as the memory is so rarely in the
- * L1 cache.
- *
- * The window buffer, however, apparently spends a lot of time in the
- * cache, and so it is faster to retrieve the word at the end of the
- * match string with two 8-bit loads. The instructions that test the
- * word at the beginning of the match string, however, are executed
- * much less frequently, and there it was cheaper to use 16-bit
- * instructions, which avoided the necessity of saving off and
- * subsequently reloading one of the other registers.

-;  longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro
-;
-;  for using an seembly version of longest_match, you need define ASMV in project
-;  There is two way in using gvmat32.asm
-;
-;  A) Suggested method
-;    if you want include both longest_match_7fff and longest_match_686
-;    compile the asm file running
-;           ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm
-;    and include gvmat32c.c in your project
-;    if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,
-;        longest_match_7fff will be used
-;    if you have a more modern CPU (Pentium Pro, II and higher)
-;        longest_match_686 will be used
-;    on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,
-;        but this is not a sitation you'll find often
-;
-;  B) Alternative
-;    if you are not interresed in old cpu performance and want the smaller
-;       binaries possible
-;
-;    compile the asm file running
-;           ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm
-;    and do not include gvmat32c.c in your project (ou define also 
-;              NOOLDPENTIUMCODE)
-;
-; note : as I known, longest_match_686 is very faster than longest_match_7fff
-;        on pentium Pro/II/III, faster (but less) in P4, but it seem
-;        longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8

 Introduction

-MiniZip64 is built from MiniZip by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
+MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
 
-When adding ZIP64 support into minizip it would result into breaking compatibility with current minizip.
+When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
-And since breaking compatibility in minizip is not wanted. I decided to create a fork of minizip 
+All possible work was done for compatibility.
-and create minizip64.
-
-Even though MiniZip64 is build from MiniZip, all functions and struct's have changed name so that it 
-would not collide with each other.
 
 
 Background
 ---------------------
-When adding ZIP64 support I found that Even Rouault have added ZIP64 support for unzip.c into minizip

+support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
 
 That was used as a starting point. And after that ZIP64 support was added to zip.c
 some refactoring and code cleanup was also done.
 
 
-Changed from MiniZip to MiniZip64
+Changed from MiniZip 1.0 to MiniZip 1.1

-* Filenames has got a '64' at the end of them . eg unzip.c is now called unzip64.c
 * Added ZIP64 support for unzip ( by Even Rouault )

 * Reverted some changed that Even Rouault did.

-   pigz compresses from stdin to stdout using threads to make use of multiple
-   processors and cores.  The input is broken up into 128 KB chunks, and each
-   is compressed separately.  The CRC for each chunk is also calculated
-   separately.  The compressed chunks are written in order to the output,
-   and the overall CRC is calculated from the CRC's of the chunks.
-
-   The compressed data format generated is the gzip format using the deflate
-   compression method.  First a gzip header is written, followed by raw deflate
-   partial streams.  They are partial, in that they do not have a terminating
-   block.  At the end, the deflate stream is terminated with a final empty
-   static block, and lastly a gzip trailer is written with the CRC and the
-   number of input bytes.
-
-   Each raw deflate partial stream is terminated by an empty stored block
-   (using the Z_SYNC_FLUSH option of zlib), in order to end that partial
-   bit stream at a byte boundary.  That allows the partial streams to be
-   concantenated simply as sequences of bytes.  This adds a very small four
-   or five byte overhead to the output for each input chunk.
-
-   zlib's crc32_combine() routine allows the calcuation of the CRC of the
-   entire input using the independent CRC's of the chunks.  pigz requires zlib
-   version 1.2.3 or later, since that is the first version that provides the
-   crc32_combine() function.
-
-   pigz uses the POSIX pthread library for thread control and communication.
