+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.)

+ * The first instruction uses a 16-bit address, which costs an extra,

+ * 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.

+;
+; this file contain two implementation of longest_match
+;
+;  longest_match_7fff : written 1996 by Gilles Vollant optimized for 
+;            first Pentium. Assume s->w_mask == 0x7fff
+;  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

-.SH NAME
-miniunzip - uncompress and examine ZIP archives
-.SH SYNOPSIS
-.B miniunzip
-.RI [ -exvlo ]
-zipfile [ files_to_extract ] [-d tempdir]
-.SH DESCRIPTION
-.B minizip
-is a simple tool which allows the extraction of compressed file
-archives in the ZIP format used by the MS-DOS utility PKZIP.  It was
-written as a demonstration of the
-.IR zlib (3)
-library and therefore lack many of the features of the
-.IR unzip (1)
-program.
-.SH OPTIONS
-A number of options are supported.  With the exception of
-.BI \-d\  tempdir
-these must be supplied before any
-other arguments and are:
-.TP
-.BI \-l\ ,\ \-\-v
-List the files in the archive without extracting them.
-.TP
-.B \-o
-Overwrite files without prompting for confirmation.
-.TP
-.B \-x
-Extract files (default).
-.PP
-The
-.I zipfile
-argument is the name of the archive to process. The next argument can be used
-to specify a single file to extract from the archive.
-
-Lastly, the following option can be specified at the end of the command-line:
-.TP
-.BI \-d\  tempdir
-Extract the archive in the directory
-.I tempdir
-rather than the current directory.
-.SH SEE ALSO
-.BR minizip (1),
-.BR zlib (3),
-.BR unzip (1).
-.SH AUTHOR
-This program was written by Gilles Vollant.  This manual page was
-written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
-was added by Dirk Eddelbuettel <edd@debian.org>.

-zipfile [ " files" ... ]
-.SH DESCRIPTION
-.B minizip
-is a simple tool which allows the creation of compressed file archives

-a demonstration of the

-library and therefore lack many of the features of the

-program.
-.SH OPTIONS
-The first argument supplied is the name of the ZIP archive to create or
-.RI -o
-in which case it is ignored and the second argument treated as the
-name of the ZIP file.  If the ZIP file already exists it will be
-overwritten.
-.PP
-Subsequent arguments specify a list of files to place in the ZIP
-archive.  If none are specified then an empty archive will be created.
