+=head1 DESCRIPTION
+
+This module provides a Perl interface that allows writing bzip2
+compressed data to files or buffer.
+
+For reading bzip2 files/buffers, see the companion module
+L<IO::Uncompress::Bunzip2|IO::Uncompress::Bunzip2>.
+
+=head1 Functional Interface
+
+A top-level function, C<bzip2>, is provided to carry out
+"one-shot" compression between buffers and/or files. For finer
+control over the compression process, see the L</"OO Interface">
+section.
+
+ use IO::Compress::Bzip2 qw(bzip2 $Bzip2Error) ;
+
+ bzip2 $input => $output [,OPTS]
+ or die "bzip2 failed: $Bzip2Error\n";
+
+The functional interface needs Perl5.005 or better.
+
+=head2 bzip2 $input => $output [, OPTS]
+
+C<bzip2> expects at least two parameters, C<$input> and C<$output>.
+
+=head3 The C<$input> parameter
+
+The parameter, C<$input>, is used to define the source of
+the uncompressed data.
+
+It can take one of the following forms:
+
+=over 5
+
+=item A filename
+
+If the C<$input> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for reading and the input data
+will be read from it.
+
+=item A filehandle
+
+If the C<$input> parameter is a filehandle, the input data will be
+read from it.
+The string '-' can be used as an alias for standard input.
+
+=item A scalar reference
+
+If C<$input> is a scalar reference, the input data will be read
+from C<$$input>.
+
+=item An array reference
+
+If C<$input> is an array reference, each element in the array must be a
+filename.
+
+The input data will be read from each file in turn.
+
+The complete array will be walked to ensure that it only
+contains valid filenames before any data is compressed.
+
+=item An Input FileGlob string
+
+If C<$input> is a string that is delimited by the characters "<" and ">"
+C<bzip2> will assume that it is an I<input fileglob string>. The
+input is the list of files that match the fileglob.
+
+If the fileglob does not match any files ...
+
+See L<File::GlobMapper|File::GlobMapper> for more details.
+
+=back
+
+If the C<$input> parameter is any other type, C<undef> will be returned.
+
+=head3 The C<$output> parameter
+
+The parameter C<$output> is used to control the destination of the
+compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed
+data will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data
+will be written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be
+stored in C<$$output>.
+
+=item An Array Reference
+
+If C<$output> is an array reference, the compressed data will be
+pushed onto the array.
+
+=item An Output FileGlob
+
+If C<$output> is a string that is delimited by the characters "<" and ">"
+C<bzip2> will assume that it is an I<output fileglob string>. The
+output is the list of files that match the fileglob.
+
+When C<$output> is an fileglob string, C<$input> must also be a fileglob
+string. Anything else is an error.
+
+=back
+
+If the C<$output> parameter is any other type, C<undef> will be returned.
+
+=head2 Notes
+
+When C<$input> maps to multiple files/buffers and C<$output> is a single
+file/buffer the input files/buffers will be stored
+in C<$output> as a concatenated series of compressed data streams.
+
+=head2 Optional Parameters
+
+Unless specified below, the optional parameters for C<bzip2>,
+C<OPTS>, are the same as those used with the OO interface defined in the
+L</"Constructor Options"> section below.
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option applies to any input or output data streams to
+C<bzip2> that are filehandles.

+
+ my $z = new IO::Compress::Bzip2 $output [,OPTS]
+ or die "IO::Compress::Bzip2 failed: $Bzip2Error\n";
+
+It returns an C<IO::Compress::Bzip2> object on success and undef on failure.
+The variable C<$Bzip2Error> will contain an error message on failure.
+
+If you are running Perl 5.005 or better the object, C<$z>, returned from
+IO::Compress::Bzip2 can be used exactly like an L<IO::File|IO::File> filehandle.
+This means that all normal output file operations can be carried out
+with C<$z>.
+For example, to write to a compressed file/buffer you can use either of
+these forms
+
+ $z->print("hello world\n");
+ print $z "hello world\n";
+
+The mandatory parameter C<$output> is used to control the destination
+of the compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed data
+will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data will be
+written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be stored
+in C<$$output>.
+
+=back
+
+If the C<$output> parameter is any other type, C<IO::Compress::Bzip2>::new will
+return undef.
+
+=head2 Constructor Options
+
+C<OPTS> is any combination of the following options:
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option is only valid when the C<$output> parameter is a filehandle. If
+specified, and the value is true, it will result in the C<$output> being
+closed once either the C<close> method is called or the C<IO::Compress::Bzip2>
+object is destroyed.
+
+This parameter defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+Opens C<$output> in append mode.
+
+The behaviour of this option is dependent on the type of C<$output>.
+
+=over 5
+
+=item * A Buffer
+
+If C<$output> is a buffer and C<Append> is enabled, all compressed data
+will be append to the end if C<$output>. Otherwise C<$output> will be
+cleared before any data is written to it.
+
+=item * A Filename
+
+If C<$output> is a filename and C<Append> is enabled, the file will be
+opened in append mode. Otherwise the contents of the file, if any, will be
+truncated before any compressed data is written to it.
+
+=item * A Filehandle
+
+If C<$output> is a filehandle, the file pointer will be positioned to the
+end of the file via a call to C<seek> before any compressed data is written
+to it. Otherwise the file pointer will not be moved.
+
+=back
+
+This parameter defaults to 0.
+
+=item C<< BlockSize100K => number >>
+
+Specify the number of 100K blocks bzip2 uses during compression.
+
+Valid values are from 1 to 9, where 9 is best compression.
+
+The default is 1.
+
+=item C<< WorkFactor => number >>
+
+Specifies how much effort bzip2 should take before resorting to a slower
+fallback compression algorithm.
+
+Valid values range from 0 to 250, where 0 means use the default value 30.
+
+The default is 0.
+
+=item C<< Strict => 0|1 >>
+
+This is a placeholder option.

+=head2 Examples
+
+TODO
+
+=head1 Methods
+
+=head2 print
+
+Usage is
+
+ $z->print($data)
+ print $z $data
+
+Compresses and outputs the contents of the C<$data> parameter. This
+has the same behaviour as the C<print> built-in.
+
+Returns true if successful.
+
+=head2 printf
+
+Usage is
+
+ $z->printf($format, $data)
+ printf $z $format, $data
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns true if successful.
+
+=head2 syswrite
+
+Usage is
+
+ $z->syswrite $data
+ $z->syswrite $data, $length
+ $z->syswrite $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 write
+
+Usage is
+
+ $z->write $data
+ $z->write $data, $length
+ $z->write $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 flush
+
+Usage is
+
+ $z->flush;
+
+Flushes any pending compressed data to the output file/buffer.
+
+TODO
+
+Returns true on success.
+
+=head2 tell
+
+Usage is
+
+ $z->tell()
+ tell $z
+
+Returns the uncompressed file offset.
+
+=head2 eof
+
+Usage is
+
+ $z->eof();
+ eof($z);
+
+Returns true if the C<close> method has been called.
+
+=head2 seek
+
+ $z->seek($position, $whence);
+ seek($z, $position, $whence);
+
+Provides a sub-set of the C<seek> functionality, with the restriction
+that it is only legal to seek forward in the output file/buffer.
+It is a fatal error to attempt to seek backward.
+
+Empty parts of the file/buffer will have NULL (0x00) bytes written to them.
+
+The C<$whence> parameter takes one the usual values, namely SEEK_SET,
+SEEK_CUR or SEEK_END.
+
+Returns 1 on success, 0 on failure.
+
+=head2 binmode
+
+Usage is
+
+ $z->binmode
+ binmode $z ;
+
+This is a noop provided for completeness.
+
+=head2 opened
+
+ $z->opened()
+
+Returns true if the object currently refers to a opened file/buffer.
+
+=head2 autoflush
+
+ my $prev = $z->autoflush()
+ my $prev = $z->autoflush(EXPR)
+
+If the C<$z> object is associated with a file or a filehandle, this method
+returns the current autoflush setting for the underlying filehandle. If
+C<EXPR> is present, and is non-zero, it will enable flushing after every
+write/print operation.
+
+If C<$z> is associated with a buffer, this method has no effect and always
+returns C<undef>.
+
+B<Note> that the special variable C<$|> B<cannot> be used to set or
+retrieve the autoflush setting.
+
+=head2 input_line_number
+
+ $z->input_line_number()
+ $z->input_line_number(EXPR)
+
+This method always returns C<undef> when compressing.
+
+=head2 fileno
+
+ $z->fileno()
+ fileno($z)
+
+If the C<$z> object is associated with a file or a filehandle, C<fileno>
+will return the underlying file descriptor. Once the C<close> method is
+called C<fileno> will return C<undef>.
+
+If the C<$z> object is is associated with a buffer, this method will return
+C<undef>.
+
+=head2 close
+
+ $z->close() ;
+ close $z ;
+
+Flushes any pending compressed data and then closes the output file/buffer.
+
+For most versions of Perl this method will be automatically invoked if
+the IO::Compress::Bzip2 object is destroyed (either explicitly or by the
+variable with the reference to the object going out of scope). The
+exceptions are Perl versions 5.005 through 5.00504 and 5.8.0. In
+these cases, the C<close> method will be called automatically, but
+not until global destruction of all live objects when the program is
+terminating.
+
+Therefore, if you want your scripts to be able to run on all versions
+of Perl, you should call C<close> explicitly and not rely on automatic
+closing.
+
+Returns true on success, otherwise 0.
+
+If the C<AutoClose> option has been enabled when the IO::Compress::Bzip2
+object was created, and the object is associated with a file, the
+underlying file will also be closed.
+
+=head2 newStream([OPTS])
+
+Usage is
+
+ $z->newStream( [OPTS] )
+
+Closes the current compressed data stream and starts a new one.
+
+OPTS consists of any of the the options that are available when creating
+the C<$z> object.
+
+See the L</"Constructor Options"> section for more details.

+=head1 DESCRIPTION
+
+This module provides a Perl interface that allows writing compressed
+data to files or buffer as defined in RFC 1950.
+
+For reading RFC 1950 files/buffers, see the companion module
+L<IO::Uncompress::Inflate|IO::Uncompress::Inflate>.
+
+=head1 Functional Interface
+
+A top-level function, C<deflate>, is provided to carry out
+"one-shot" compression between buffers and/or files. For finer
+control over the compression process, see the L</"OO Interface">
+section.
+
+ use IO::Compress::Deflate qw(deflate $DeflateError) ;
+
+ deflate $input => $output [,OPTS]
+ or die "deflate failed: $DeflateError\n";
+
+The functional interface needs Perl5.005 or better.
+
+=head2 deflate $input => $output [, OPTS]
+
+C<deflate> expects at least two parameters, C<$input> and C<$output>.
+
+=head3 The C<$input> parameter
+
+The parameter, C<$input>, is used to define the source of
+the uncompressed data.
+
+It can take one of the following forms:
+
+=over 5
+
+=item A filename
+
+If the C<$input> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for reading and the input data
+will be read from it.
+
+=item A filehandle
+
+If the C<$input> parameter is a filehandle, the input data will be
+read from it.
+The string '-' can be used as an alias for standard input.
+
+=item A scalar reference
+
+If C<$input> is a scalar reference, the input data will be read
+from C<$$input>.
+
+=item An array reference
+
+If C<$input> is an array reference, each element in the array must be a
+filename.
+
+The input data will be read from each file in turn.
+
+The complete array will be walked to ensure that it only
+contains valid filenames before any data is compressed.
+
+=item An Input FileGlob string
+
+If C<$input> is a string that is delimited by the characters "<" and ">"
+C<deflate> will assume that it is an I<input fileglob string>. The
+input is the list of files that match the fileglob.
+
+If the fileglob does not match any files ...
+
+See L<File::GlobMapper|File::GlobMapper> for more details.
+
+=back
+
+If the C<$input> parameter is any other type, C<undef> will be returned.
+
+=head3 The C<$output> parameter
+
+The parameter C<$output> is used to control the destination of the
+compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed
+data will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data
+will be written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be
+stored in C<$$output>.
+
+=item An Array Reference
+
+If C<$output> is an array reference, the compressed data will be
+pushed onto the array.
+
+=item An Output FileGlob
+
+If C<$output> is a string that is delimited by the characters "<" and ">"
+C<deflate> will assume that it is an I<output fileglob string>. The
+output is the list of files that match the fileglob.
+
+When C<$output> is an fileglob string, C<$input> must also be a fileglob
+string. Anything else is an error.
+
+=back
+
+If the C<$output> parameter is any other type, C<undef> will be returned.
+
+=head2 Notes
+
+When C<$input> maps to multiple files/buffers and C<$output> is a single
+file/buffer the input files/buffers will be stored
+in C<$output> as a concatenated series of compressed data streams.
+
+=head2 Optional Parameters
+
+Unless specified below, the optional parameters for C<deflate>,
+C<OPTS>, are the same as those used with the OO interface defined in the
+L</"Constructor Options"> section below.
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option applies to any input or output data streams to
+C<deflate> that are filehandles.
+
+If C<AutoClose> is specified, and the value is true, it will result in all
+input and/or output filehandles being closed once C<deflate> has
+completed.
+
+This parameter defaults to 0.
+
+=item C<< BinModeIn => 0|1 >>
+
+When reading from a file or filehandle, set C<binmode> before reading.
+
+Defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+The behaviour of this option is dependent on the type of output data
+stream.
+
+=over 5
+
+=item * A Buffer
+
+If C<Append> is enabled, all compressed data will be append to the end of
+the output buffer. Otherwise the output buffer will be cleared before any
+compressed data is written to it.
+
+=item * A Filename
+
+If C<Append> is enabled, the file will be opened in append mode. Otherwise
+the contents of the file, if any, will be truncated before any compressed
+data is written to it.
+
+=item * A Filehandle
+
+If C<Append> is enabled, the filehandle will be positioned to the end of
+the file via a call to C<seek> before any compressed data is
+written to it. Otherwise the file pointer will not be moved.
+
+=back
+
+When C<Append> is specified, and set to true, it will I<append> all compressed
+data to the output data stream.
+
+So when the output is a filehandle it will carry out a seek to the eof
+before writing any compressed data. If the output is a filename, it will be opened for
+appending. If the output is a buffer, all compressed data will be appened to
+the existing buffer.
+
+Conversely when C<Append> is not specified, or it is present and is set to
+false, it will operate as follows.
+
+When the output is a filename, it will truncate the contents of the file
+before writing any compressed data. If the output is a filehandle
+its position will not be changed. If the output is a buffer, it will be
+wiped before any compressed data is output.
+
+Defaults to 0.
+
+=back
+
+=head2 Examples
+
+To read the contents of the file C<file1.txt> and write the compressed
+data to the file C<file1.txt.1950>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Deflate qw(deflate $DeflateError) ;

+
+=head1 OO Interface
+
+=head2 Constructor
+
+The format of the constructor for C<IO::Compress::Deflate> is shown below
+
+ my $z = new IO::Compress::Deflate $output [,OPTS]
+ or die "IO::Compress::Deflate failed: $DeflateError\n";
+
+It returns an C<IO::Compress::Deflate> object on success and undef on failure.
+The variable C<$DeflateError> will contain an error message on failure.
+
+If you are running Perl 5.005 or better the object, C<$z>, returned from
+IO::Compress::Deflate can be used exactly like an L<IO::File|IO::File> filehandle.
+This means that all normal output file operations can be carried out
+with C<$z>.
+For example, to write to a compressed file/buffer you can use either of
+these forms
+
+ $z->print("hello world\n");
+ print $z "hello world\n";
+
+The mandatory parameter C<$output> is used to control the destination
+of the compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed data
+will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data will be
+written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be stored
+in C<$$output>.
+
+=back
+
+If the C<$output> parameter is any other type, C<IO::Compress::Deflate>::new will
+return undef.
+
+=head2 Constructor Options
+
+C<OPTS> is any combination of the following options:
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option is only valid when the C<$output> parameter is a filehandle. If
+specified, and the value is true, it will result in the C<$output> being
+closed once either the C<close> method is called or the C<IO::Compress::Deflate>
+object is destroyed.
+
+This parameter defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+Opens C<$output> in append mode.
+
+The behaviour of this option is dependent on the type of C<$output>.
+
+=over 5
+
+=item * A Buffer
+
+If C<$output> is a buffer and C<Append> is enabled, all compressed data
+will be append to the end of C<$output>. Otherwise C<$output> will be
+cleared before any data is written to it.
+
+=item * A Filename
+
+If C<$output> is a filename and C<Append> is enabled, the file will be
+opened in append mode. Otherwise the contents of the file, if any, will be
+truncated before any compressed data is written to it.
+
+=item * A Filehandle
+
+If C<$output> is a filehandle, the file pointer will be positioned to the
+end of the file via a call to C<seek> before any compressed data is written
+to it. Otherwise the file pointer will not be moved.
+
+=back
+
+This parameter defaults to 0.
+
+=item C<< Merge => 0|1 >>
+
+This option is used to compress input data and append it to an existing
+compressed data stream in C<$output>. The end result is a single compressed
+data stream stored in C<$output>.
+
+It is a fatal error to attempt to use this option when C<$output> is not an
+RFC 1950 data stream.
+
+There are a number of other limitations with the C<Merge> option:
+
+=over 5
+
+=item 1
+
+This module needs to have been built with zlib 1.2.1 or better to work. A
+fatal error will be thrown if C<Merge> is used with an older version of
+zlib.
+
+=item 2
+
+If C<$output> is a file or a filehandle, it must be seekable.
+
+=back
+
+This parameter defaults to 0.
+
+=item -Level
+
+Defines the compression level used by zlib. The value should either be
+a number between 0 and 9 (0 means no compression and 9 is maximum
+compression), or one of the symbolic constants defined below.
+
+ Z_NO_COMPRESSION
+ Z_BEST_SPEED
+ Z_BEST_COMPRESSION
+ Z_DEFAULT_COMPRESSION
+
+The default is Z_DEFAULT_COMPRESSION.
+
+Note, these constants are not imported by C<IO::Compress::Deflate> by default.
+
+ use IO::Compress::Deflate qw(:strategy);
+ use IO::Compress::Deflate qw(:constants);
+ use IO::Compress::Deflate qw(:all);
+
+=item -Strategy
+
+Defines the strategy used to tune the compression. Use one of the symbolic
+constants defined below.
+
+ Z_FILTERED
+ Z_HUFFMAN_ONLY
+ Z_RLE
+ Z_FIXED
+ Z_DEFAULT_STRATEGY
+
+The default is Z_DEFAULT_STRATEGY.
+
+=item C<< Strict => 0|1 >>
+
+This is a placeholder option.

+=head2 Examples
+
+TODO
+
+=head1 Methods
+
+=head2 print
+
+Usage is
+
+ $z->print($data)
+ print $z $data
+
+Compresses and outputs the contents of the C<$data> parameter. This
+has the same behaviour as the C<print> built-in.
+
+Returns true if successful.
+
+=head2 printf
+
+Usage is
+
+ $z->printf($format, $data)
+ printf $z $format, $data
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns true if successful.
+
+=head2 syswrite
+
+Usage is
+
+ $z->syswrite $data
+ $z->syswrite $data, $length
+ $z->syswrite $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 write
+
+Usage is
+
+ $z->write $data
+ $z->write $data, $length
+ $z->write $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 flush
+
+Usage is
+
+ $z->flush;
+ $z->flush($flush_type);
+
+Flushes any pending compressed data to the output file/buffer.
+
+This method takes an optional parameter, C<$flush_type>, that controls
+how the flushing will be carried out. By default the C<$flush_type>
+used is C<Z_FINISH>. Other valid values for C<$flush_type> are
+C<Z_NO_FLUSH>, C<Z_SYNC_FLUSH>, C<Z_FULL_FLUSH> and C<Z_BLOCK>. It is
+strongly recommended that you only set the C<flush_type> parameter if
+you fully understand the implications of what it does - overuse of C<flush>
+can seriously degrade the level of compression achieved. See the C<zlib>
+documentation for details.
+
+Returns true on success.
+
+=head2 tell
+
+Usage is
+
+ $z->tell()
+ tell $z
+
+Returns the uncompressed file offset.
+
+=head2 eof
+
+Usage is
+
+ $z->eof();
+ eof($z);
+
+Returns true if the C<close> method has been called.
+
+=head2 seek
+
+ $z->seek($position, $whence);
+ seek($z, $position, $whence);
+
+Provides a sub-set of the C<seek> functionality, with the restriction
+that it is only legal to seek forward in the output file/buffer.
+It is a fatal error to attempt to seek backward.
+
+Empty parts of the file/buffer will have NULL (0x00) bytes written to them.
+
+The C<$whence> parameter takes one the usual values, namely SEEK_SET,
+SEEK_CUR or SEEK_END.
+
+Returns 1 on success, 0 on failure.
+
+=head2 binmode
+
+Usage is
+
+ $z->binmode
+ binmode $z ;
+
+This is a noop provided for completeness.
+
+=head2 opened
+
+ $z->opened()
+
+Returns true if the object currently refers to a opened file/buffer.
+
+=head2 autoflush
+
+ my $prev = $z->autoflush()
+ my $prev = $z->autoflush(EXPR)
+
+If the C<$z> object is associated with a file or a filehandle, this method
+returns the current autoflush setting for the underlying filehandle. If
+C<EXPR> is present, and is non-zero, it will enable flushing after every
+write/print operation.
+
+If C<$z> is associated with a buffer, this method has no effect and always
+returns C<undef>.
+
+B<Note> that the special variable C<$|> B<cannot> be used to set or
+retrieve the autoflush setting.
+
+=head2 input_line_number
+
+ $z->input_line_number()
+ $z->input_line_number(EXPR)
+
+This method always returns C<undef> when compressing.
+
+=head2 fileno
+
+ $z->fileno()
+ fileno($z)
+
+If the C<$z> object is associated with a file or a filehandle, C<fileno>
+will return the underlying file descriptor. Once the C<close> method is
+called C<fileno> will return C<undef>.
+
+If the C<$z> object is is associated with a buffer, this method will return
+C<undef>.
+
+=head2 close
+
+ $z->close() ;
+ close $z ;
+
+Flushes any pending compressed data and then closes the output file/buffer.
+
+For most versions of Perl this method will be automatically invoked if
+the IO::Compress::Deflate object is destroyed (either explicitly or by the
+variable with the reference to the object going out of scope). The
+exceptions are Perl versions 5.005 through 5.00504 and 5.8.0. In
+these cases, the C<close> method will be called automatically, but
+not until global destruction of all live objects when the program is
+terminating.
+
+Therefore, if you want your scripts to be able to run on all versions
+of Perl, you should call C<close> explicitly and not rely on automatic
+closing.
+
+Returns true on success, otherwise 0.
+
+If the C<AutoClose> option has been enabled when the IO::Compress::Deflate
+object was created, and the object is associated with a file, the
+underlying file will also be closed.
+
+=head2 newStream([OPTS])
+
+Usage is
+
+ $z->newStream( [OPTS] )
+
+Closes the current compressed data stream and starts a new one.
+
+OPTS consists of any of the the options that are available when creating
+the C<$z> object.
+
+See the L</"Constructor Options"> section for more details.
+
+=head2 deflateParams
+
+Usage is
+
+ $z->deflateParams
+
+TODO
+
+=head1 Importing

+=head1 DESCRIPTION
+
+This module provides a Perl interface that allows writing compressed
+data to files or buffer as defined in RFC 1952.
+
+All the gzip headers defined in RFC 1952 can be created using

+For reading RFC 1952 files/buffers, see the companion module
+L<IO::Uncompress::Gunzip|IO::Uncompress::Gunzip>.
+
+=head1 Functional Interface
+
+A top-level function, C<gzip>, is provided to carry out
+"one-shot" compression between buffers and/or files. For finer
+control over the compression process, see the L</"OO Interface">
+section.
+
+ use IO::Compress::Gzip qw(gzip $GzipError) ;
+
+ gzip $input => $output [,OPTS]
+ or die "gzip failed: $GzipError\n";
+
+The functional interface needs Perl5.005 or better.
+
+=head2 gzip $input => $output [, OPTS]
+
+C<gzip> expects at least two parameters, C<$input> and C<$output>.
+
+=head3 The C<$input> parameter
+
+The parameter, C<$input>, is used to define the source of
+the uncompressed data.
+
+It can take one of the following forms:
+
+=over 5
+
+=item A filename
+
+If the C<$input> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for reading and the input data
+will be read from it.
+
+=item A filehandle
+
+If the C<$input> parameter is a filehandle, the input data will be
+read from it.
+The string '-' can be used as an alias for standard input.
+
+=item A scalar reference
+
+If C<$input> is a scalar reference, the input data will be read
+from C<$$input>.
+
+=item An array reference
+
+If C<$input> is an array reference, each element in the array must be a
+filename.
+
+The input data will be read from each file in turn.
+
+The complete array will be walked to ensure that it only
+contains valid filenames before any data is compressed.
+
+=item An Input FileGlob string
+
+If C<$input> is a string that is delimited by the characters "<" and ">"
+C<gzip> will assume that it is an I<input fileglob string>. The
+input is the list of files that match the fileglob.
+
+If the fileglob does not match any files ...
+
+See L<File::GlobMapper|File::GlobMapper> for more details.
+
+=back
+
+If the C<$input> parameter is any other type, C<undef> will be returned.
+
+In addition, if C<$input> is a simple filename, the default values for
+the C<Name> and C<Time> options will be sourced from that file.
+
+If you do not want to use these defaults they can be overridden by
+explicitly setting the C<Name> and C<Time> options or by setting the
+C<Minimal> parameter.
+
+=head3 The C<$output> parameter
+
+The parameter C<$output> is used to control the destination of the
+compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed
+data will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data
+will be written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be
+stored in C<$$output>.
+
+=item An Array Reference
+
+If C<$output> is an array reference, the compressed data will be
+pushed onto the array.
+
+=item An Output FileGlob
+
+If C<$output> is a string that is delimited by the characters "<" and ">"
+C<gzip> will assume that it is an I<output fileglob string>. The
+output is the list of files that match the fileglob.
+
+When C<$output> is an fileglob string, C<$input> must also be a fileglob
+string. Anything else is an error.
+
+=back
+
+If the C<$output> parameter is any other type, C<undef> will be returned.
+
+=head2 Notes
+
+When C<$input> maps to multiple files/buffers and C<$output> is a single
+file/buffer the input files/buffers will be stored
+in C<$output> as a concatenated series of compressed data streams.
+
+=head2 Optional Parameters
+
+Unless specified below, the optional parameters for C<gzip>,
+C<OPTS>, are the same as those used with the OO interface defined in the
+L</"Constructor Options"> section below.
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option applies to any input or output data streams to
+C<gzip> that are filehandles.
+
+If C<AutoClose> is specified, and the value is true, it will result in all
+input and/or output filehandles being closed once C<gzip> has
+completed.
+
+This parameter defaults to 0.
+
+=item C<< BinModeIn => 0|1 >>
+
+When reading from a file or filehandle, set C<binmode> before reading.
+
+Defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+The behaviour of this option is dependent on the type of output data
+stream.
+
+=over 5
+
+=item * A Buffer
+
+If C<Append> is enabled, all compressed data will be append to the end of
+the output buffer. Otherwise the output buffer will be cleared before any
+compressed data is written to it.
+
+=item * A Filename
+
+If C<Append> is enabled, the file will be opened in append mode. Otherwise
+the contents of the file, if any, will be truncated before any compressed
+data is written to it.
+
+=item * A Filehandle
+
+If C<Append> is enabled, the filehandle will be positioned to the end of
+the file via a call to C<seek> before any compressed data is
+written to it. Otherwise the file pointer will not be moved.
+
+=back
+
+When C<Append> is specified, and set to true, it will I<append> all compressed
+data to the output data stream.
+
+So when the output is a filehandle it will carry out a seek to the eof
+before writing any compressed data. If the output is a filename, it will be opened for
+appending. If the output is a buffer, all compressed data will be appened to
+the existing buffer.
+
+Conversely when C<Append> is not specified, or it is present and is set to
+false, it will operate as follows.
+
+When the output is a filename, it will truncate the contents of the file
+before writing any compressed data. If the output is a filehandle
+its position will not be changed. If the output is a buffer, it will be
+wiped before any compressed data is output.
+
+Defaults to 0.
+
+=back
+
+=head2 Examples
+
+To read the contents of the file C<file1.txt> and write the compressed
+data to the file C<file1.txt.gz>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Gzip qw(gzip $GzipError) ;
+
+ my $input = "file1.txt";
+ gzip $input => "$input.gz"
+ or die "gzip failed: $GzipError\n";
+
+To read from an existing Perl filehandle, C<$input>, and write the
+compressed data to a buffer, C<$buffer>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Gzip qw(gzip $GzipError) ;
+ use IO::File ;
+
+ my $input = new IO::File "<file1.txt"
+ or die "Cannot open 'file1.txt': $!\n" ;
+ my $buffer ;
+ gzip $input => \$buffer
+ or die "gzip failed: $GzipError\n";
+
+To compress all files in the directory "/my/home" that match "*.txt"
+and store the compressed data in the same directory
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Gzip qw(gzip $GzipError) ;
+
+ gzip '</my/home/*.txt>' => '<*.gz>'
+ or die "gzip failed: $GzipError\n";
+
+and if you want to compress each file one at a time, this will do the trick
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Gzip qw(gzip $GzipError) ;
+
+ for my $input ( glob "/my/home/*.txt" )
+ {
+ my $output = "$input.gz" ;
+ gzip $input => $output
+ or die "Error compressing '$input': $GzipError\n";
+ }
+
+=head1 OO Interface
+
+=head2 Constructor
+
+The format of the constructor for C<IO::Compress::Gzip> is shown below
+
+ my $z = new IO::Compress::Gzip $output [,OPTS]
+ or die "IO::Compress::Gzip failed: $GzipError\n";
+
+It returns an C<IO::Compress::Gzip> object on success and undef on failure.
+The variable C<$GzipError> will contain an error message on failure.
+
+If you are running Perl 5.005 or better the object, C<$z>, returned from
+IO::Compress::Gzip can be used exactly like an L<IO::File|IO::File> filehandle.
+This means that all normal output file operations can be carried out
+with C<$z>.
+For example, to write to a compressed file/buffer you can use either of
+these forms
+
+ $z->print("hello world\n");
+ print $z "hello world\n";
+
+The mandatory parameter C<$output> is used to control the destination
+of the compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed data
+will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data will be
+written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be stored
+in C<$$output>.
+
+=back
+
+If the C<$output> parameter is any other type, C<IO::Compress::Gzip>::new will
+return undef.
+
+=head2 Constructor Options
+
+C<OPTS> is any combination of the following options:
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option is only valid when the C<$output> parameter is a filehandle. If
+specified, and the value is true, it will result in the C<$output> being
+closed once either the C<close> method is called or the C<IO::Compress::Gzip>
+object is destroyed.
+
+This parameter defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+Opens C<$output> in append mode.
+
+The behaviour of this option is dependent on the type of C<$output>.
+
+=over 5
+
+=item * A Buffer
+
+If C<$output> is a buffer and C<Append> is enabled, all compressed data
+will be append to the end of C<$output>. Otherwise C<$output> will be
+cleared before any data is written to it.
+
+=item * A Filename
+
+If C<$output> is a filename and C<Append> is enabled, the file will be
+opened in append mode. Otherwise the contents of the file, if any, will be
+truncated before any compressed data is written to it.
+
+=item * A Filehandle
+
+If C<$output> is a filehandle, the file pointer will be positioned to the
+end of the file via a call to C<seek> before any compressed data is written
+to it. Otherwise the file pointer will not be moved.
+
+=back
+
+This parameter defaults to 0.
+
+=item C<< Merge => 0|1 >>
+
+This option is used to compress input data and append it to an existing
+compressed data stream in C<$output>. The end result is a single compressed
+data stream stored in C<$output>.
+
+It is a fatal error to attempt to use this option when C<$output> is not an
+RFC 1952 data stream.
+
+There are a number of other limitations with the C<Merge> option:
+
+=over 5
+
+=item 1
+
+This module needs to have been built with zlib 1.2.1 or better to work. A
+fatal error will be thrown if C<Merge> is used with an older version of
+zlib.
+
+=item 2
+
+If C<$output> is a file or a filehandle, it must be seekable.
+
+=back
+
+This parameter defaults to 0.
+
+=item -Level
+
+Defines the compression level used by zlib. The value should either be
+a number between 0 and 9 (0 means no compression and 9 is maximum
+compression), or one of the symbolic constants defined below.
+
+ Z_NO_COMPRESSION
+ Z_BEST_SPEED
+ Z_BEST_COMPRESSION
+ Z_DEFAULT_COMPRESSION
+
+The default is Z_DEFAULT_COMPRESSION.
+
+Note, these constants are not imported by C<IO::Compress::Gzip> by default.
+
+ use IO::Compress::Gzip qw(:strategy);
+ use IO::Compress::Gzip qw(:constants);
+ use IO::Compress::Gzip qw(:all);
+
+=item -Strategy
+
+Defines the strategy used to tune the compression. Use one of the symbolic
+constants defined below.
+
+ Z_FILTERED
+ Z_HUFFMAN_ONLY
+ Z_RLE
+ Z_FIXED
+ Z_DEFAULT_STRATEGY
+
+The default is Z_DEFAULT_STRATEGY.
+
+=item C<< Minimal => 0|1 >>
+
+If specified, this option will force the creation of the smallest possible
+compliant gzip header (which is exactly 10 bytes long) as defined in
+RFC 1952.
+
+See the section titled "Compliance" in RFC 1952 for a definition
+of the values used for the fields in the gzip header.
+
+All other parameters that control the content of the gzip header will
+be ignored if this parameter is set to 1.
+
+This parameter defaults to 0.
+
+=item C<< Comment => $comment >>
+
+Stores the contents of C<$comment> in the COMMENT field in
+the gzip header.
+By default, no comment field is written to the gzip file.
+
+If the C<-Strict> option is enabled, the comment can only consist of ISO
+8859-1 characters plus line feed.
+
+If the C<-Strict> option is disabled, the comment field can contain any
+character except NULL. If any null characters are present, the field
+will be truncated at the first NULL.
+
+=item C<< Name => $string >>
+
+Stores the contents of C<$string> in the gzip NAME header field. If
+C<Name> is not specified, no gzip NAME field will be created.
+
+If the C<-Strict> option is enabled, C<$string> can only consist of ISO
+8859-1 characters.
+
+If C<-Strict> is disabled, then C<$string> can contain any character
+except NULL. If any null characters are present, the field will be
+truncated at the first NULL.
+
+=item C<< Time => $number >>
+
+Sets the MTIME field in the gzip header to $number.
+
+This field defaults to the time the C<IO::Compress::Gzip> object was created
+if this option is not specified.
+
+=item C<< TextFlag => 0|1 >>
+
+This parameter controls the setting of the FLG.FTEXT bit in the gzip
+header. It is used to signal that the data stored in the gzip file/buffer
+is probably text.
+
+The default is 0.
+
+=item C<< HeaderCRC => 0|1 >>
+
+When true this parameter will set the FLG.FHCRC bit to 1 in the gzip header
+and set the CRC16 header field to the CRC of the complete gzip header
+except the CRC16 field itself.
+
+B<Note> that gzip files created with the C<HeaderCRC> flag set to 1 cannot
+be read by most, if not all, of the the standard gunzip utilities, most
+notably gzip version 1.2.4. You should therefore avoid using this option if
+you want to maximize the portability of your gzip files.
+
+This parameter defaults to 0.
+
+=item C<< OS_Code => $value >>
+
+Stores C<$value> in the gzip OS header field. A number between 0 and 255 is
+valid.
+
+If not specified, this parameter defaults to the OS code of the Operating
+System this module was built on. The value 3 is used as a catch-all for all
+Unix variants and unknown Operating Systems.
+
+=item C<< ExtraField => $data >>
+
+This parameter allows additional metadata to be stored in the ExtraField in
+the gzip header. An RFC 1952 compliant ExtraField consists of zero or more
+subfields. Each subfield consists of a two byte header followed by the
+subfield data.
+
+The list of subfields can be supplied in any of the following formats
+
+ -ExtraField => [$id1, $data1,
+ $id2, $data2,
+ ...
+ ]
+ -ExtraField => [ [$id1 => $data1],
+ [$id2 => $data2],
+ ...
+ ]
+ -ExtraField => { $id1 => $data1,
+ $id2 => $data2,
+ ...
+ }
+
+Where C<$id1>, C<$id2> are two byte subfield ID's. The second byte of
+the ID cannot be 0, unless the C<Strict> option has been disabled.
+
+If you use the hash syntax, you have no control over the order in which
+the ExtraSubFields are stored, plus you cannot have SubFields with
+duplicate ID.
+
+Alternatively the list of subfields can by supplied as a scalar, thus
+
+ -ExtraField => $rawdata
+
+If you use the raw format, and the C<Strict> option is enabled,
+C<IO::Compress::Gzip> will check that C<$rawdata> consists of zero or more
+conformant sub-fields. When C<Strict> is disabled, C<$rawdata> can
+consist of any arbitrary byte stream.
+
+The maximum size of the Extra Field 65535 bytes.
+
+=item C<< ExtraFlags => $value >>
+
+Sets the XFL byte in the gzip header to C<$value>.
+
+If this option is not present, the value stored in XFL field will be
+determined by the setting of the C<Level> option.
+
+If C<< Level => Z_BEST_SPEED >> has been specified then XFL is set to 2.
+If C<< Level => Z_BEST_COMPRESSION >> has been specified then XFL is set to 4.
+Otherwise XFL is set to 0.
+
+=item C<< Strict => 0|1 >>
+
+C<Strict> will optionally police the values supplied with other options
+to ensure they are compliant with RFC1952.
+
+This option is enabled by default.
+
+If C<Strict> is enabled the following behaviour will be policed:
+
+=over 5
+
+=item *
+
+The value supplied with the C<Name> option can only contain ISO 8859-1
+characters.
+
+=item *
+
+The value supplied with the C<Comment> option can only contain ISO 8859-1
+characters plus line-feed.
+
+=item *
+
+The values supplied with the C<-Name> and C<-Comment> options cannot
+contain multiple embedded nulls.
+
+=item *
+
+If an C<ExtraField> option is specified and it is a simple scalar,
+it must conform to the sub-field structure as defined in RFC 1952.
+
+=item *
+
+If an C<ExtraField> option is specified the second byte of the ID will be
+checked in each subfield to ensure that it does not contain the reserved
+value 0x00.
+
+=back
+
+When C<Strict> is disabled the following behaviour will be policed:
+
+=over 5
+
+=item *
+
+The value supplied with C<-Name> option can contain
+any character except NULL.
+
+=item *
+
+The value supplied with C<-Comment> option can contain any character
+except NULL.
+
+=item *
+
+The values supplied with the C<-Name> and C<-Comment> options can contain
+multiple embedded nulls. The string written to the gzip header will
+consist of the characters up to, but not including, the first embedded
+NULL.
+
+=item *
+
+If an C<ExtraField> option is specified and it is a simple scalar, the
+structure will not be checked. The only error is if the length is too big.
+
+=item *
+
+The ID header in an C<ExtraField> sub-field can consist of any two bytes.

+
+=head2 syswrite
+
+Usage is

+ $z->syswrite $data
+ $z->syswrite $data, $length
+ $z->syswrite $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if

+
+=head2 write
+
+Usage is
+
+ $z->write $data
+ $z->write $data, $length
+ $z->write $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 flush
+
+Usage is
+
+ $z->flush;
+ $z->flush($flush_type);
+
+Flushes any pending compressed data to the output file/buffer.
+
+This method takes an optional parameter, C<$flush_type>, that controls
+how the flushing will be carried out. By default the C<$flush_type>
+used is C<Z_FINISH>. Other valid values for C<$flush_type> are
+C<Z_NO_FLUSH>, C<Z_SYNC_FLUSH>, C<Z_FULL_FLUSH> and C<Z_BLOCK>. It is
+strongly recommended that you only set the C<flush_type> parameter if
+you fully understand the implications of what it does - overuse of C<flush>
+can seriously degrade the level of compression achieved. See the C<zlib>
+documentation for details.
+
+Returns true on success.
+
+=head2 tell
+
+Usage is
+
+ $z->tell()
+ tell $z
+
+Returns the uncompressed file offset.
+
+=head2 eof
+
+Usage is
+
+ $z->eof();
+ eof($z);
+
+Returns true if the C<close> method has been called.
+
+=head2 seek
+
+ $z->seek($position, $whence);
+ seek($z, $position, $whence);
+
+Provides a sub-set of the C<seek> functionality, with the restriction
+that it is only legal to seek forward in the output file/buffer.
+It is a fatal error to attempt to seek backward.
+
+Empty parts of the file/buffer will have NULL (0x00) bytes written to them.
+
+The C<$whence> parameter takes one the usual values, namely SEEK_SET,
+SEEK_CUR or SEEK_END.
+
+Returns 1 on success, 0 on failure.

+Usage is
+
+ $z->binmode
+ binmode $z ;
+
+This is a noop provided for completeness.

+
+Returns true if the object currently refers to a opened file/buffer.
+
+=head2 autoflush
+
+ my $prev = $z->autoflush()
+ my $prev = $z->autoflush(EXPR)
+
+If the C<$z> object is associated with a file or a filehandle, this method
+returns the current autoflush setting for the underlying filehandle. If
+C<EXPR> is present, and is non-zero, it will enable flushing after every
+write/print operation.
+
+If C<$z> is associated with a buffer, this method has no effect and always
+returns C<undef>.
+
+B<Note> that the special variable C<$|> B<cannot> be used to set or
+retrieve the autoflush setting.
+
+=head2 input_line_number
+
+ $z->input_line_number()
+ $z->input_line_number(EXPR)
+
+This method always returns C<undef> when compressing.
+
+=head2 fileno
+
+ $z->fileno()
+ fileno($z)
+
+If the C<$z> object is associated with a file or a filehandle, C<fileno>
+will return the underlying file descriptor. Once the C<close> method is
+called C<fileno> will return C<undef>.
+
+If the C<$z> object is is associated with a buffer, this method will return
+C<undef>.
+
+=head2 close
+
+ $z->close() ;
+ close $z ;
+
+Flushes any pending compressed data and then closes the output file/buffer.
+
+For most versions of Perl this method will be automatically invoked if
+the IO::Compress::Gzip object is destroyed (either explicitly or by the
+variable with the reference to the object going out of scope). The
+exceptions are Perl versions 5.005 through 5.00504 and 5.8.0. In
+these cases, the C<close> method will be called automatically, but
+not until global destruction of all live objects when the program is
+terminating.
+
+Therefore, if you want your scripts to be able to run on all versions
+of Perl, you should call C<close> explicitly and not rely on automatic
+closing.
+
+Returns true on success, otherwise 0.
+
+If the C<AutoClose> option has been enabled when the IO::Compress::Gzip
+object was created, and the object is associated with a file, the
+underlying file will also be closed.
+
+=head2 newStream([OPTS])
+
+Usage is

+
+Closes the current compressed data stream and starts a new one.
+
+OPTS consists of any of the the options that are available when creating

+=head1 DESCRIPTION
+
+This module provides a Perl interface that allows writing compressed
+data to files or buffer as defined in RFC 1951.
+
+Note that RFC 1951 data is not a good choice of compression format
+to use in isolation, especially if you want to auto-detect it.
+
+For reading RFC 1951 files/buffers, see the companion module
+L<IO::Uncompress::RawInflate|IO::Uncompress::RawInflate>.
+
+=head1 Functional Interface
+
+A top-level function, C<rawdeflate>, is provided to carry out
+"one-shot" compression between buffers and/or files. For finer
+control over the compression process, see the L</"OO Interface">
+section.
+
+ use IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;
+
+ rawdeflate $input => $output [,OPTS]
+ or die "rawdeflate failed: $RawDeflateError\n";
+
+The functional interface needs Perl5.005 or better.
+
+=head2 rawdeflate $input => $output [, OPTS]
+
+C<rawdeflate> expects at least two parameters, C<$input> and C<$output>.
+
+=head3 The C<$input> parameter
+
+The parameter, C<$input>, is used to define the source of
+the uncompressed data.
+
+It can take one of the following forms:
+
+=over 5
+
+=item A filename
+
+If the C<$input> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for reading and the input data
+will be read from it.
+
+=item A filehandle
+
+If the C<$input> parameter is a filehandle, the input data will be
+read from it.
+The string '-' can be used as an alias for standard input.
+
+=item A scalar reference
+
+If C<$input> is a scalar reference, the input data will be read
+from C<$$input>.
+
+=item An array reference
+
+If C<$input> is an array reference, each element in the array must be a
+filename.
+
+The input data will be read from each file in turn.
+
+The complete array will be walked to ensure that it only
+contains valid filenames before any data is compressed.
+
+=item An Input FileGlob string
+
+If C<$input> is a string that is delimited by the characters "<" and ">"
+C<rawdeflate> will assume that it is an I<input fileglob string>. The
+input is the list of files that match the fileglob.
+
+If the fileglob does not match any files ...
+
+See L<File::GlobMapper|File::GlobMapper> for more details.
+
+=back
+
+If the C<$input> parameter is any other type, C<undef> will be returned.
+
+=head3 The C<$output> parameter
+
+The parameter C<$output> is used to control the destination of the
+compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed
+data will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data
+will be written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be
+stored in C<$$output>.
+
+=item An Array Reference
+
+If C<$output> is an array reference, the compressed data will be
+pushed onto the array.
+
+=item An Output FileGlob
+
+If C<$output> is a string that is delimited by the characters "<" and ">"
+C<rawdeflate> will assume that it is an I<output fileglob string>. The
+output is the list of files that match the fileglob.
+
+When C<$output> is an fileglob string, C<$input> must also be a fileglob
+string. Anything else is an error.
+
+=back
+
+If the C<$output> parameter is any other type, C<undef> will be returned.
+
+=head2 Notes
+
+When C<$input> maps to multiple files/buffers and C<$output> is a single
+file/buffer the input files/buffers will be stored
+in C<$output> as a concatenated series of compressed data streams.
+
+=head2 Optional Parameters
+
+Unless specified below, the optional parameters for C<rawdeflate>,
+C<OPTS>, are the same as those used with the OO interface defined in the
+L</"Constructor Options"> section below.
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option applies to any input or output data streams to
+C<rawdeflate> that are filehandles.
+
+If C<AutoClose> is specified, and the value is true, it will result in all
+input and/or output filehandles being closed once C<rawdeflate> has
+completed.
+
+This parameter defaults to 0.
+
+=item C<< BinModeIn => 0|1 >>
+
+When reading from a file or filehandle, set C<binmode> before reading.
+
+Defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+The behaviour of this option is dependent on the type of output data
+stream.
+
+=over 5
+
+=item * A Buffer
+
+If C<Append> is enabled, all compressed data will be append to the end of
+the output buffer. Otherwise the output buffer will be cleared before any
+compressed data is written to it.
+
+=item * A Filename
+
+If C<Append> is enabled, the file will be opened in append mode. Otherwise
+the contents of the file, if any, will be truncated before any compressed
+data is written to it.
+
+=item * A Filehandle
+
+If C<Append> is enabled, the filehandle will be positioned to the end of
+the file via a call to C<seek> before any compressed data is
+written to it. Otherwise the file pointer will not be moved.
+
+=back
+
+When C<Append> is specified, and set to true, it will I<append> all compressed
+data to the output data stream.
+
+So when the output is a filehandle it will carry out a seek to the eof
+before writing any compressed data. If the output is a filename, it will be opened for
+appending. If the output is a buffer, all compressed data will be appened to
+the existing buffer.
+
+Conversely when C<Append> is not specified, or it is present and is set to
+false, it will operate as follows.
+
+When the output is a filename, it will truncate the contents of the file
+before writing any compressed data. If the output is a filehandle
+its position will not be changed. If the output is a buffer, it will be
+wiped before any compressed data is output.
+
+Defaults to 0.
+
+=back
+
+=head2 Examples
+
+To read the contents of the file C<file1.txt> and write the compressed
+data to the file C<file1.txt.1951>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;
+
+ my $input = "file1.txt";
+ rawdeflate $input => "$input.1951"
+ or die "rawdeflate failed: $RawDeflateError\n";
+
+To read from an existing Perl filehandle, C<$input>, and write the
+compressed data to a buffer, C<$buffer>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;
+ use IO::File ;
+
+ my $input = new IO::File "<file1.txt"
+ or die "Cannot open 'file1.txt': $!\n" ;
+ my $buffer ;
+ rawdeflate $input => \$buffer
+ or die "rawdeflate failed: $RawDeflateError\n";
+
+To compress all files in the directory "/my/home" that match "*.txt"
+and store the compressed data in the same directory
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;
+
+ rawdeflate '</my/home/*.txt>' => '<*.1951>'
+ or die "rawdeflate failed: $RawDeflateError\n";
+
+and if you want to compress each file one at a time, this will do the trick
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::RawDeflate qw(rawdeflate $RawDeflateError) ;
+
+ for my $input ( glob "/my/home/*.txt" )
+ {
+ my $output = "$input.1951" ;
+ rawdeflate $input => $output
+ or die "Error compressing '$input': $RawDeflateError\n";
+ }
+
+=head1 OO Interface
+
+=head2 Constructor
+
+The format of the constructor for C<IO::Compress::RawDeflate> is shown below
+
+ my $z = new IO::Compress::RawDeflate $output [,OPTS]
+ or die "IO::Compress::RawDeflate failed: $RawDeflateError\n";
+
+It returns an C<IO::Compress::RawDeflate> object on success and undef on failure.
+The variable C<$RawDeflateError> will contain an error message on failure.
+
+If you are running Perl 5.005 or better the object, C<$z>, returned from
+IO::Compress::RawDeflate can be used exactly like an L<IO::File|IO::File> filehandle.
+This means that all normal output file operations can be carried out
+with C<$z>.
+For example, to write to a compressed file/buffer you can use either of
+these forms
+
+ $z->print("hello world\n");
+ print $z "hello world\n";
+
+The mandatory parameter C<$output> is used to control the destination
+of the compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed data
+will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data will be
+written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be stored
+in C<$$output>.
+
+=back
+
+If the C<$output> parameter is any other type, C<IO::Compress::RawDeflate>::new will
+return undef.
+
+=head2 Constructor Options
+
+C<OPTS> is any combination of the following options:
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option is only valid when the C<$output> parameter is a filehandle. If
+specified, and the value is true, it will result in the C<$output> being
+closed once either the C<close> method is called or the C<IO::Compress::RawDeflate>
+object is destroyed.
+
+This parameter defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+Opens C<$output> in append mode.
+
+The behaviour of this option is dependent on the type of C<$output>.
+
+=over 5
+
+=item * A Buffer
+
+If C<$output> is a buffer and C<Append> is enabled, all compressed data
+will be append to the end of C<$output>. Otherwise C<$output> will be
+cleared before any data is written to it.
+
+=item * A Filename
+
+If C<$output> is a filename and C<Append> is enabled, the file will be
+opened in append mode. Otherwise the contents of the file, if any, will be
+truncated before any compressed data is written to it.
+
+=item * A Filehandle
+
+If C<$output> is a filehandle, the file pointer will be positioned to the
+end of the file via a call to C<seek> before any compressed data is written
+to it. Otherwise the file pointer will not be moved.
+
+=back
+
+This parameter defaults to 0.
+
+=item C<< Merge => 0|1 >>
+
+This option is used to compress input data and append it to an existing
+compressed data stream in C<$output>. The end result is a single compressed
+data stream stored in C<$output>.
+
+It is a fatal error to attempt to use this option when C<$output> is not an
+RFC 1951 data stream.
+
+There are a number of other limitations with the C<Merge> option:
+
+=over 5
+
+=item 1
+
+This module needs to have been built with zlib 1.2.1 or better to work. A
+fatal error will be thrown if C<Merge> is used with an older version of
+zlib.
+
+=item 2
+
+If C<$output> is a file or a filehandle, it must be seekable.
+
+=back
+
+This parameter defaults to 0.
+
+=item -Level
+
+Defines the compression level used by zlib. The value should either be
+a number between 0 and 9 (0 means no compression and 9 is maximum
+compression), or one of the symbolic constants defined below.
+
+ Z_NO_COMPRESSION
+ Z_BEST_SPEED
+ Z_BEST_COMPRESSION
+ Z_DEFAULT_COMPRESSION
+
+The default is Z_DEFAULT_COMPRESSION.
+
+Note, these constants are not imported by C<IO::Compress::RawDeflate> by default.
+
+ use IO::Compress::RawDeflate qw(:strategy);
+ use IO::Compress::RawDeflate qw(:constants);
+ use IO::Compress::RawDeflate qw(:all);
+
+=item -Strategy
+
+Defines the strategy used to tune the compression. Use one of the symbolic
+constants defined below.
+
+ Z_FILTERED
+ Z_HUFFMAN_ONLY
+ Z_RLE
+ Z_FIXED
+ Z_DEFAULT_STRATEGY
+
+The default is Z_DEFAULT_STRATEGY.
+
+=item C<< Strict => 0|1 >>
+
+This is a placeholder option.

+=head2 Examples
+
+TODO
+
+=head1 Methods
+
+=head2 print
+
+Usage is
+
+ $z->print($data)
+ print $z $data
+
+Compresses and outputs the contents of the C<$data> parameter. This
+has the same behaviour as the C<print> built-in.
+
+Returns true if successful.
+
+=head2 printf
+
+Usage is
+
+ $z->printf($format, $data)
+ printf $z $format, $data
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns true if successful.
+
+=head2 syswrite
+
+Usage is
+
+ $z->syswrite $data
+ $z->syswrite $data, $length
+ $z->syswrite $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 write
+
+Usage is
+
+ $z->write $data
+ $z->write $data, $length
+ $z->write $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 flush
+
+Usage is
+
+ $z->flush;
+ $z->flush($flush_type);
+
+Flushes any pending compressed data to the output file/buffer.
+
+This method takes an optional parameter, C<$flush_type>, that controls
+how the flushing will be carried out. By default the C<$flush_type>
+used is C<Z_FINISH>. Other valid values for C<$flush_type> are
+C<Z_NO_FLUSH>, C<Z_SYNC_FLUSH>, C<Z_FULL_FLUSH> and C<Z_BLOCK>. It is
+strongly recommended that you only set the C<flush_type> parameter if
+you fully understand the implications of what it does - overuse of C<flush>
+can seriously degrade the level of compression achieved. See the C<zlib>
+documentation for details.
+
+Returns true on success.
+
+=head2 tell
+
+Usage is
+
+ $z->tell()
+ tell $z
+
+Returns the uncompressed file offset.
+
+=head2 eof
+
+Usage is
+
+ $z->eof();
+ eof($z);
+
+Returns true if the C<close> method has been called.
+
+=head2 seek
+
+ $z->seek($position, $whence);
+ seek($z, $position, $whence);
+
+Provides a sub-set of the C<seek> functionality, with the restriction
+that it is only legal to seek forward in the output file/buffer.
+It is a fatal error to attempt to seek backward.
+
+Empty parts of the file/buffer will have NULL (0x00) bytes written to them.
+
+The C<$whence> parameter takes one the usual values, namely SEEK_SET,
+SEEK_CUR or SEEK_END.
+
+Returns 1 on success, 0 on failure.
+
+=head2 binmode
+
+Usage is
+
+ $z->binmode
+ binmode $z ;
+
+This is a noop provided for completeness.
+
+=head2 opened
+
+ $z->opened()
+
+Returns true if the object currently refers to a opened file/buffer.
+
+=head2 autoflush
+
+ my $prev = $z->autoflush()
+ my $prev = $z->autoflush(EXPR)
+
+If the C<$z> object is associated with a file or a filehandle, this method
+returns the current autoflush setting for the underlying filehandle. If
+C<EXPR> is present, and is non-zero, it will enable flushing after every
+write/print operation.
+
+If C<$z> is associated with a buffer, this method has no effect and always
+returns C<undef>.
+
+B<Note> that the special variable C<$|> B<cannot> be used to set or
+retrieve the autoflush setting.
+
+=head2 input_line_number
+
+ $z->input_line_number()
+ $z->input_line_number(EXPR)
+
+This method always returns C<undef> when compressing.
+
+=head2 fileno
+
+ $z->fileno()
+ fileno($z)
+
+If the C<$z> object is associated with a file or a filehandle, C<fileno>
+will return the underlying file descriptor. Once the C<close> method is
+called C<fileno> will return C<undef>.
+
+If the C<$z> object is is associated with a buffer, this method will return
+C<undef>.
+
+=head2 close
+
+ $z->close() ;
+ close $z ;
+
+Flushes any pending compressed data and then closes the output file/buffer.
+
+For most versions of Perl this method will be automatically invoked if
+the IO::Compress::RawDeflate object is destroyed (either explicitly or by the
+variable with the reference to the object going out of scope). The
+exceptions are Perl versions 5.005 through 5.00504 and 5.8.0. In
+these cases, the C<close> method will be called automatically, but
+not until global destruction of all live objects when the program is
+terminating.
+
+Therefore, if you want your scripts to be able to run on all versions
+of Perl, you should call C<close> explicitly and not rely on automatic
+closing.
+
+Returns true on success, otherwise 0.
+
+If the C<AutoClose> option has been enabled when the IO::Compress::RawDeflate
+object was created, and the object is associated with a file, the
+underlying file will also be closed.
+
+=head2 newStream([OPTS])
+
+Usage is
+
+ $z->newStream( [OPTS] )
+
+Closes the current compressed data stream and starts a new one.
+
+OPTS consists of any of the the options that are available when creating
+the C<$z> object.
+
+See the L</"Constructor Options"> section for more details.
+
+=head2 deflateParams
+
+Usage is
+
+ $z->deflateParams
+
+TODO

+=head1 DESCRIPTION
+
+This module provides a Perl interface that allows writing zip
+compressed data to files or buffer.
+
+The primary purpose of this module is to provide streaming write access to
+zip files and buffers. It is not a general-purpose file archiver. If that
+is what you want, check out C<Archive::Zip>.
+
+At present three compression methods are supported by IO::Compress::Zip,
+namely Store (no compression at all), Deflate and Bzip2.
+
+Note that to create Bzip2 content, the module C<IO::Compress::Bzip2> must
+be installed.
+
+For reading zip files/buffers, see the companion module
+L<IO::Uncompress::Unzip|IO::Uncompress::Unzip>.
+
+=head1 Functional Interface
+
+A top-level function, C<zip>, is provided to carry out
+"one-shot" compression between buffers and/or files. For finer
+control over the compression process, see the L</"OO Interface">
+section.
+
+ use IO::Compress::Zip qw(zip $ZipError) ;
+
+ zip $input => $output [,OPTS]
+ or die "zip failed: $ZipError\n";
+
+The functional interface needs Perl5.005 or better.
+
+=head2 zip $input => $output [, OPTS]
+
+C<zip> expects at least two parameters, C<$input> and C<$output>.
+
+=head3 The C<$input> parameter
+
+The parameter, C<$input>, is used to define the source of
+the uncompressed data.
+
+It can take one of the following forms:
+
+=over 5
+
+=item A filename
+
+If the C<$input> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for reading and the input data
+will be read from it.
+
+=item A filehandle
+
+If the C<$input> parameter is a filehandle, the input data will be
+read from it.
+The string '-' can be used as an alias for standard input.
+
+=item A scalar reference
+
+If C<$input> is a scalar reference, the input data will be read
+from C<$$input>.
+
+=item An array reference
+
+If C<$input> is an array reference, each element in the array must be a
+filename.
+
+The input data will be read from each file in turn.
+
+The complete array will be walked to ensure that it only
+contains valid filenames before any data is compressed.
+
+=item An Input FileGlob string
+
+If C<$input> is a string that is delimited by the characters "<" and ">"
+C<zip> will assume that it is an I<input fileglob string>. The
+input is the list of files that match the fileglob.
+
+If the fileglob does not match any files ...
+
+See L<File::GlobMapper|File::GlobMapper> for more details.
+
+=back
+
+If the C<$input> parameter is any other type, C<undef> will be returned.
+
+In addition, if C<$input> is a simple filename, the default values for
+the C<Name>, C<Time>, C<ExtAttr> and C<exTime> options will be sourced from that file.
+
+If you do not want to use these defaults they can be overridden by
+explicitly setting the C<Name>, C<Time>, C<ExtAttr> and C<exTime> options or by setting the
+C<Minimal> parameter.
+
+=head3 The C<$output> parameter
+
+The parameter C<$output> is used to control the destination of the
+compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed
+data will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data
+will be written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be
+stored in C<$$output>.
+
+=item An Array Reference
+
+If C<$output> is an array reference, the compressed data will be
+pushed onto the array.
+
+=item An Output FileGlob
+
+If C<$output> is a string that is delimited by the characters "<" and ">"
+C<zip> will assume that it is an I<output fileglob string>. The
+output is the list of files that match the fileglob.
+
+When C<$output> is an fileglob string, C<$input> must also be a fileglob
+string. Anything else is an error.
+
+=back
+
+If the C<$output> parameter is any other type, C<undef> will be returned.
+
+=head2 Notes
+
+When C<$input> maps to multiple files/buffers and C<$output> is a single
+file/buffer the input files/buffers will each be stored
+in C<$output> as a distinct entry.
+
+=head2 Optional Parameters
+
+Unless specified below, the optional parameters for C<zip>,
+C<OPTS>, are the same as those used with the OO interface defined in the
+L</"Constructor Options"> section below.
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option applies to any input or output data streams to
+C<zip> that are filehandles.
+
+If C<AutoClose> is specified, and the value is true, it will result in all
+input and/or output filehandles being closed once C<zip> has
+completed.
+
+This parameter defaults to 0.
+
+=item C<< BinModeIn => 0|1 >>
+
+When reading from a file or filehandle, set C<binmode> before reading.
+
+Defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+The behaviour of this option is dependent on the type of output data
+stream.
+
+=over 5
+
+=item * A Buffer
+
+If C<Append> is enabled, all compressed data will be append to the end of
+the output buffer. Otherwise the output buffer will be cleared before any
+compressed data is written to it.
+
+=item * A Filename
+
+If C<Append> is enabled, the file will be opened in append mode. Otherwise
+the contents of the file, if any, will be truncated before any compressed
+data is written to it.
+
+=item * A Filehandle
+
+If C<Append> is enabled, the filehandle will be positioned to the end of
+the file via a call to C<seek> before any compressed data is
+written to it. Otherwise the file pointer will not be moved.
+
+=back
+
+When C<Append> is specified, and set to true, it will I<append> all compressed
+data to the output data stream.
+
+So when the output is a filehandle it will carry out a seek to the eof
+before writing any compressed data. If the output is a filename, it will be opened for
+appending. If the output is a buffer, all compressed data will be appened to
+the existing buffer.
+
+Conversely when C<Append> is not specified, or it is present and is set to
+false, it will operate as follows.
+
+When the output is a filename, it will truncate the contents of the file
+before writing any compressed data. If the output is a filehandle
+its position will not be changed. If the output is a buffer, it will be
+wiped before any compressed data is output.
+
+Defaults to 0.
+
+=back
+
+=head2 Examples
+
+To read the contents of the file C<file1.txt> and write the compressed
+data to the file C<file1.txt.zip>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Zip qw(zip $ZipError) ;
+
+ my $input = "file1.txt";
+ zip $input => "$input.zip"
+ or die "zip failed: $ZipError\n";
+
+To read from an existing Perl filehandle, C<$input>, and write the
+compressed data to a buffer, C<$buffer>.
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Zip qw(zip $ZipError) ;
+ use IO::File ;
+
+ my $input = new IO::File "<file1.txt"
+ or die "Cannot open 'file1.txt': $!\n" ;
+ my $buffer ;
+ zip $input => \$buffer
+ or die "zip failed: $ZipError\n";
+
+To compress all files in the directory "/my/home" that match "*.txt"
+and store the compressed data in the same directory
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Zip qw(zip $ZipError) ;
+
+ zip '</my/home/*.txt>' => '<*.zip>'
+ or die "zip failed: $ZipError\n";
+
+and if you want to compress each file one at a time, this will do the trick
+
+ use strict ;
+ use warnings ;
+ use IO::Compress::Zip qw(zip $ZipError) ;
+
+ for my $input ( glob "/my/home/*.txt" )
+ {
+ my $output = "$input.zip" ;
+ zip $input => $output
+ or die "Error compressing '$input': $ZipError\n";
+ }
+
+=head1 OO Interface
+
+=head2 Constructor
+
+The format of the constructor for C<IO::Compress::Zip> is shown below
+
+ my $z = new IO::Compress::Zip $output [,OPTS]
+ or die "IO::Compress::Zip failed: $ZipError\n";
+
+It returns an C<IO::Compress::Zip> object on success and undef on failure.
+The variable C<$ZipError> will contain an error message on failure.
+
+If you are running Perl 5.005 or better the object, C<$z>, returned from
+IO::Compress::Zip can be used exactly like an L<IO::File|IO::File> filehandle.
+This means that all normal output file operations can be carried out
+with C<$z>.
+For example, to write to a compressed file/buffer you can use either of
+these forms
+
+ $z->print("hello world\n");
+ print $z "hello world\n";
+
+The mandatory parameter C<$output> is used to control the destination
+of the compressed data. This parameter can take one of these forms.
+
+=over 5
+
+=item A filename
+
+If the C<$output> parameter is a simple scalar, it is assumed to be a
+filename. This file will be opened for writing and the compressed data
+will be written to it.
+
+=item A filehandle
+
+If the C<$output> parameter is a filehandle, the compressed data will be
+written to it.
+The string '-' can be used as an alias for standard output.
+
+=item A scalar reference
+
+If C<$output> is a scalar reference, the compressed data will be stored
+in C<$$output>.
+
+=back
+
+If the C<$output> parameter is any other type, C<IO::Compress::Zip>::new will
+return undef.
+
+=head2 Constructor Options
+
+C<OPTS> is any combination of the following options:
+
+=over 5
+
+=item C<< AutoClose => 0|1 >>
+
+This option is only valid when the C<$output> parameter is a filehandle. If
+specified, and the value is true, it will result in the C<$output> being
+closed once either the C<close> method is called or the C<IO::Compress::Zip>
+object is destroyed.
+
+This parameter defaults to 0.
+
+=item C<< Append => 0|1 >>
+
+Opens C<$output> in append mode.
+
+The behaviour of this option is dependent on the type of C<$output>.
+
+=over 5
+
+=item * A Buffer
+
+If C<$output> is a buffer and C<Append> is enabled, all compressed data
+will be append to the end of C<$output>. Otherwise C<$output> will be
+cleared before any data is written to it.
+
+=item * A Filename
+
+If C<$output> is a filename and C<Append> is enabled, the file will be
+opened in append mode. Otherwise the contents of the file, if any, will be
+truncated before any compressed data is written to it.
+
+=item * A Filehandle
+
+If C<$output> is a filehandle, the file pointer will be positioned to the
+end of the file via a call to C<seek> before any compressed data is written
+to it. Otherwise the file pointer will not be moved.
+
+=back
+
+This parameter defaults to 0.
+
+=item C<< Name => $string >>
+
+Stores the contents of C<$string> in the zip filename header field. If
+C<Name> is not specified, no zip filename field will be created.
+
+=item C<< Time => $number >>
+
+Sets the last modified time field in the zip header to $number.
+
+This field defaults to the time the C<IO::Compress::Zip> object was created
+if this option is not specified.
+
+=item C<< ExtAttr => $attr >>
+
+This option controls the "external file attributes" field in the central
+header of the zip file. This is a 4 byte field.
+
+If you are running a Unix derivative this value defaults to
+
+ 0666 << 16
+
+This should allow read/write access to any files that are extracted from
+the zip file/buffer.
+
+For all other systems it defaults to 0.
+
+=item C<< exTime => [$atime, $mtime, $ctime] >>
+
+This option expects an array reference with exactly three elements:
+C<$atime>, C<mtime> and C<$ctime>. These correspond to the last access
+time, last modification time and creation time respectively.
+
+It uses these values to set the extended timestamp field (ID is "UT") in
+the local zip header using the three values, $atime, $mtime, $ctime. In
+addition it sets the extended timestamp field in the central zip header
+using C<$mtime>.
+
+If any of the three values is C<undef> that time value will not be used.
+So, for example, to set only the C<$mtime> you would use this
+
+ exTime => [undef, $mtime, undef]
+
+If the C<Minimal> option is set to true, this option will be ignored.
+
+By default no extended time field is created.
+
+=item C<< exUnix2 => [$uid, $gid] >>
+
+This option expects an array reference with exactly two elements: C<$uid>
+and C<$gid>. These values correspond to the numeric user ID and group ID
+of the owner of the files respectively.
+
+When the C<exUnix2> option is present it will trigger the creation of a
+Unix2 extra field (ID is "Ux") in the local zip. This will be populated
+with C<$uid> and C<$gid>. In addition an empty Unix2 extra field will also
+be created in the central zip header
+
+If the C<Minimal> option is set to true, this option will be ignored.
+
+By default no Unix2 extra field is created.
+
+=item C<< Comment => $comment >>
+
+Stores the contents of C<$comment> in the Central File Header of
+the zip file.
+
+By default, no comment field is written to the zip file.
+
+=item C<< ZipComment => $comment >>
+
+Stores the contents of C<$comment> in the End of Central Directory record
+of the zip file.
+
+By default, no comment field is written to the zip file.
+
+=item C<< Method => $method >>
+
+Controls which compression method is used. At present three compression
+methods are supported, namely Store (no compression at all), Deflate and
+Bzip2.
+
+The symbols, ZIP_CM_STORE, ZIP_CM_DEFLATE and ZIP_CM_BZIP2 are used to
+select the compression method.
+
+These constants are not imported by C<IO::Compress::Zip> by default.
+
+ use IO::Compress::Zip qw(:zip_method);
+ use IO::Compress::Zip qw(:constants);
+ use IO::Compress::Zip qw(:all);
+
+Note that to create Bzip2 content, the module C<IO::Compress::Bzip2> must
+be installed. A fatal error will be thrown if you attempt to create Bzip2
+content when C<IO::Compress::Bzip2> is not available.
+
+The default method is ZIP_CM_DEFLATE.
+
+=item C<< Stream => 0|1 >>
+
+This option controls whether the zip file/buffer output is created in
+streaming mode.
+
+Note that when outputting to a file with streaming mode disabled (C<Stream>
+is 0), the output file must be seekable.
+
+The default is 1.
+
+=item C<< Zip64 => 0|1 >>
+
+Create a Zip64 zip file/buffer. This option should only be used if you want
+to store files larger than 4 Gig.
+
+If you intend to manipulate the Zip64 zip files created with this module
+using an external zip/unzip make sure that it supports Zip64.
+
+In particular, if you are using Info-Zip you need to have zip version 3.x
+or better to update a Zip64 archive and unzip version 6.x to read a zip64
+archive.
+
+The default is 0.
+
+=item C<< TextFlag => 0|1 >>
+
+This parameter controls the setting of a bit in the zip central header. It
+is used to signal that the data stored in the zip file/buffer is probably
+text.
+
+The default is 0.
+
+=item C<< ExtraFieldLocal => $data >>
+=item C<< ExtraFieldCentral => $data >>
+
+The C<ExtraFieldLocal> option is used to store additional metadata in the
+local header for the zip file/buffer. The C<ExtraFieldCentral> does the
+same for the matching central header.
+
+An extra field consists of zero or more subfields. Each subfield consists
+of a two byte header followed by the subfield data.
+
+The list of subfields can be supplied in any of the following formats
+
+ ExtraFieldLocal => [$id1, $data1,
+ $id2, $data2,
+ ...
+ ]
+
+ ExtraFieldLocal => [ [$id1 => $data1],
+ [$id2 => $data2],
+ ...
+ ]
+
+ ExtraFieldLocal => { $id1 => $data1,
+ $id2 => $data2,
+ ...
+ }
+
+Where C<$id1>, C<$id2> are two byte subfield ID's.
+
+If you use the hash syntax, you have no control over the order in which
+the ExtraSubFields are stored, plus you cannot have SubFields with
+duplicate ID.
+
+Alternatively the list of subfields can by supplied as a scalar, thus
+
+ ExtraField => $rawdata
+
+The Extended Time field (ID "UT"), set using the C<exTime> option, and the
+Unix2 extra field (ID "Ux), set using the C<exUnix2> option, are examples
+of extra fields.
+
+If the C<Minimal> option is set to true, this option will be ignored.
+
+The maximum size of an extra field 65535 bytes.
+
+=item C<< Minimal => 1|0 >>
+
+If specified, this option will disable the creation of all extra fields
+in the zip local and central headers. So the C<exTime>, C<exUnix2>,
+C<ExtraFieldLocal> and C<ExtraFieldCentral> options will be ignored.
+
+This parameter defaults to 0.
+
+=item C<< BlockSize100K => number >>
+
+Specify the number of 100K blocks bzip2 uses during compression.
+
+Valid values are from 1 to 9, where 9 is best compression.
+
+This option is only valid if the C<Method> is ZIP_CM_BZIP2. It is ignored
+otherwise.
+
+The default is 1.
+
+=item C<< WorkFactor => number >>
+
+Specifies how much effort bzip2 should take before resorting to a slower
+fallback compression algorithm.
+
+Valid values range from 0 to 250, where 0 means use the default value 30.
+
+This option is only valid if the C<Method> is ZIP_CM_BZIP2. It is ignored
+otherwise.
+
+The default is 0.
+
+=item -Level
+
+Defines the compression level used by zlib. The value should either be
+a number between 0 and 9 (0 means no compression and 9 is maximum
+compression), or one of the symbolic constants defined below.
+
+ Z_NO_COMPRESSION
+ Z_BEST_SPEED
+ Z_BEST_COMPRESSION
+ Z_DEFAULT_COMPRESSION
+
+The default is Z_DEFAULT_COMPRESSION.
+
+Note, these constants are not imported by C<IO::Compress::Zip> by default.
+
+ use IO::Compress::Zip qw(:strategy);
+ use IO::Compress::Zip qw(:constants);
+ use IO::Compress::Zip qw(:all);
+
+=item -Strategy
+
+Defines the strategy used to tune the compression. Use one of the symbolic
+constants defined below.
+
+ Z_FILTERED
+ Z_HUFFMAN_ONLY
+ Z_RLE
+ Z_FIXED
+ Z_DEFAULT_STRATEGY
+
+The default is Z_DEFAULT_STRATEGY.
+
+=item C<< Strict => 0|1 >>
+
+This is a placeholder option.

+=head2 Examples
+
+TODO
+
+=head1 Methods
+
+=head2 print
+
+Usage is
+
+ $z->print($data)
+ print $z $data
+
+Compresses and outputs the contents of the C<$data> parameter. This
+has the same behaviour as the C<print> built-in.
+
+Returns true if successful.
+
+=head2 printf
+
+Usage is
+
+ $z->printf($format, $data)
+ printf $z $format, $data
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns true if successful.
+
+=head2 syswrite
+
+Usage is
+
+ $z->syswrite $data
+ $z->syswrite $data, $length
+ $z->syswrite $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 write
+
+Usage is
+
+ $z->write $data
+ $z->write $data, $length
+ $z->write $data, $length, $offset
+
+Compresses and outputs the contents of the C<$data> parameter.
+
+Returns the number of uncompressed bytes written, or C<undef> if
+unsuccessful.
+
+=head2 flush
+
+Usage is
+
+ $z->flush;
+ $z->flush($flush_type);
+
+Flushes any pending compressed data to the output file/buffer.
+
+This method takes an optional parameter, C<$flush_type>, that controls
+how the flushing will be carried out. By default the C<$flush_type>
+used is C<Z_FINISH>. Other valid values for C<$flush_type> are
+C<Z_NO_FLUSH>, C<Z_SYNC_FLUSH>, C<Z_FULL_FLUSH> and C<Z_BLOCK>. It is
+strongly recommended that you only set the C<flush_type> parameter if
+you fully understand the implications of what it does - overuse of C<flush>
+can seriously degrade the level of compression achieved. See the C<zlib>
+documentation for details.
+
+Returns true on success.
+
+=head2 tell
+
+Usage is
+
+ $z->tell()
+ tell $z
+
+Returns the uncompressed file offset.
+
+=head2 eof
+
+Usage is
+
+ $z->eof();
+ eof($z);
+
+Returns true if the C<close> method has been called.
+
+=head2 seek
+
+ $z->seek($position, $whence);
+ seek($z, $position, $whence);
+
+Provides a sub-set of the C<seek> functionality, with the restriction
+that it is only legal to seek forward in the output file/buffer.
+It is a fatal error to attempt to seek backward.
+
+Empty parts of the file/buffer will have NULL (0x00) bytes written to them.
+
+The C<$whence> parameter takes one the usual values, namely SEEK_SET,
+SEEK_CUR or SEEK_END.
+
+Returns 1 on success, 0 on failure.
+
+=head2 binmode
+
+Usage is
+
+ $z->binmode
+ binmode $z ;
+
+This is a noop provided for completeness.
+
+=head2 opened
+
+ $z->opened()
+
+Returns true if the object currently refers to a opened file/buffer.
+
+=head2 autoflush
+
+ my $prev = $z->autoflush()
+ my $prev = $z->autoflush(EXPR)
+
+If the C<$z> object is associated with a file or a filehandle, this method
+returns the current autoflush setting for the underlying filehandle. If
+C<EXPR> is present, and is non-zero, it will enable flushing after every
+write/print operation.
+
+If C<$z> is associated with a buffer, this method has no effect and always
+returns C<undef>.
+
+B<Note> that the special variable C<$|> B<cannot> be used to set or
+retrieve the autoflush setting.
+
+=head2 input_line_number
+
+ $z->input_line_number()
+ $z->input_line_number(EXPR)
+
+This method always returns C<undef> when compressing.
+
+=head2 fileno
+
+ $z->fileno()
+ fileno($z)
+
+If the C<$z> object is associated with a file or a filehandle, C<fileno>
+will return the underlying file descriptor. Once the C<close> method is
+called C<fileno> will return C<undef>.
+
+If the C<$z> object is is associated with a buffer, this method will return
+C<undef>.
+
+=head2 close
+
+ $z->close() ;
+ close $z ;
+
+Flushes any pending compressed data and then closes the output file/buffer.
+
+For most versions of Perl this method will be automatically invoked if
+the IO::Compress::Zip object is destroyed (either explicitly or by the
+variable with the reference to the object going out of scope). The
+exceptions are Perl versions 5.005 through 5.00504 and 5.8.0. In
+these cases, the C<close> method will be called automatically, but
+not until global destruction of all live objects when the program is
+terminating.
+
+Therefore, if you want your scripts to be able to run on all versions
+of Perl, you should call C<close> explicitly and not rely on automatic
+closing.
+
+Returns true on success, otherwise 0.
+
+If the C<AutoClose> option has been enabled when the IO::Compress::Zip
+object was created, and the object is associated with a file, the
+underlying file will also be closed.
+
+=head2 newStream([OPTS])
+
+Usage is
+
+ $z->newStream( [OPTS] )
+
+Closes the current compressed data stream and starts a new one.
+
+OPTS consists of any of the the options that are available when creating
+the C<$z> object.
+
+See the L</"Constructor Options"> section for more details.
+
+=head2 deflateParams
+
+Usage is
+
+ $z->deflateParams
+
+TODO
