DESCRIPTION
-----------
-
This module provides a Perl interface to the zlib compression library.
-
-
-
-
PREREQUISITES
-------------
Before you can build Compress-Raw-Zlib you need to have the following
installed on your system:
-
* A C compiler
* Perl 5.004 or better.
-
-
By default, Compress-Raw-Zlib will build its own private copy of the
zlib library. If you want to use a different version of
zlib, follow the instructions in the section called
"Controlling the version of zlib used by Compress-Raw-Zlib"
later in this document.

TROUBLESHOOTING
---------------
+Undefined Symbol gzsetparams
+----------------------------
+If you get the error shown below when you run the Compress-Raw-Zlib test
+harness it probably means you are running a copy of zlib that is
+version 1.0.5 or older.
+t/01version.........Can't load 'blib/arch/auto/Compress/Zlib/Zlib.so' for
+ module Compress::Raw::Zlib: blib/arch/auto/Compress/Raw/Zlib/Zlib.so:
+ undefined symbol: gzsetparams at ...
+There are two ways to fix this problem:
+ 1. Upgrade to the latest version of zlib.
+ 2. Edit config.in and set the OLD_ZLIB variable to True.
+
+Test Harness 01version fails
+----------------------------
+If the 01version test harness fails, and the problem isn't covered by the
+scenario above, it probably means that you have two versions of
+zlib installed on your system.
+
+Run the command below to see if this is indeed the case
+
+ make test TEST_VERBOSE=1 TEST_FILES=t/01version.t
+
+Try removing the one you don't want to use and rebuild.

+=head1 NAME
+
+Compress::Raw::Zlib::FAQ -- Frequently Asked Questions about Compress::Raw::Zlib
+
+=head1 DESCRIPTION
+
+Common questions answered.
+
+=head2 Compatibility with Unix compress/uncompress.
+
+This module is not compatible with Unix C<compress>.
+
+If you have the C<uncompress> program available, you can use this to read
+compressed files
+
+ open F, "uncompress -c $filename |";
+ while (<F>)
+ {
+ ...
+
+Alternatively, if you have the C<gunzip> program available, you can use
+this to read compressed files
+
+ open F, "gunzip -c $filename |";
+ while (<F>)
+ {
+ ...
+
+and this to write compress files, if you have the C<compress> program
+available
+
+ open F, "| compress -c $filename ";
+ print F "data";
+ ...
+ close F ;
+
+=head2 Accessing .tar.Z files
+
+See previous FAQ item.
+
+If the C<Archive::Tar> module is installed and either the C<uncompress> or
+C<gunzip> programs are available, you can use one of these workarounds to
+read C<.tar.Z> files.
+
+Firstly with C<uncompress>
+
+ use strict;
+ use warnings;
+ use Archive::Tar;
+
+ open F, "uncompress -c $filename |";
+ my $tar = Archive::Tar->new(*F);
+ ...
+
+and this with C<gunzip>
+
+ use strict;
+ use warnings;
+ use Archive::Tar;
+
+ open F, "gunzip -c $filename |";
+ my $tar = Archive::Tar->new(*F);
+ ...
+
+Similarly, if the C<compress> program is available, you can use this to
+write a C<.tar.Z> file
+
+ use strict;
+ use warnings;
+ use Archive::Tar;
+ use IO::File;
+
+ my $fh = new IO::File "| compress -c >$filename";
+ my $tar = Archive::Tar->new();
+ ...
+ $tar->write($fh);
+ $fh->close ;
+
+=head2 Accessing Zip Files
+
+This module does not support reading/writing zip files.
+
+Support for reading/writing zip files is included with the
+C<IO::Compress::Zip> and C<IO::Uncompress::Unzip> modules.
+
+The primary focus of the C<IO::Compress::Zip> and C<IO::Uncompress::Unzip>
+modules is to provide an C<IO::File> compatible streaming read/write
+interface to zip files/buffers. They are not fully flegged archivers. If
+you are looking for an archiver check out the C<Archive::Zip> module. You
+can find it on CPAN at
+
+ http://www.cpan.org/modules/by-module/Archive/Archive-Zip-*.tar.gz
+
+=head2 Zlib Library Version Support
+
+By default C<Compress::Raw::Zlib> will build with a private copy of version
+1.2.3 of the zlib library. (See the F<README> file for details of
+how to override this behaviour)
+
+If you decide to use a different version of the zlib library, you need to be
+aware of the following issues
+
+=over 5
+
+=item *
+
+First off, you must have zlib 1.0.5 or better.
+
+=item *
+
+You need to have zlib 1.2.1 or better if you want to use the C<-Merge>
+option with C<IO::Compress::Gzip>, C<IO::Compress::Deflate> and
+C<IO::Compress::RawDeflate>.
