=head1 DESCRIPTION
This module provides a Perl interface that allows the reading of
files/buffers that have been compressed with a variety of compression
libraries.
The formats supported are:
=over 5
=item RFC 1950
=item RFC 1951 (optionally)
=item gzip (RFC 1952)
=item zip
=item bzip2
=item lzop
=item lzf
=item lzma
=item xz
=back
The module will auto-detect which, if any, of the supported
compression formats is being used.
=head1 Functional Interface
A top-level function, C, is provided to carry out
"one-shot" uncompression between buffers and/or files. For finer
control over the uncompression process, see the L
section.
use IO::Uncompress::AnyUncompress qw(anyuncompress $AnyUncompressError) ;
anyuncompress $input_filename_or_reference => $output_filename_or_reference [,OPTS]
or die "anyuncompress failed: $AnyUncompressError\n";
The functional interface needs Perl5.005 or better.
=head2 anyuncompress $input_filename_or_reference => $output_filename_or_reference [, OPTS]
C expects at least two parameters,
C<$input_filename_or_reference> and C<$output_filename_or_reference>.
=head3 The C<$input_filename_or_reference> parameter
The parameter, C<$input_filename_or_reference>, is used to define the
source of the compressed data.
It can take one of the following forms:
=over 5
=item A filename
If the <$input_filename_or_reference> 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<$input_filename_or_reference> parameter is a filehandle, the input
data will be read from it. The string '-' can be used as an alias for
standard input.
=item A scalar reference
If C<$input_filename_or_reference> is a scalar reference, the input data
will be read from C<$$input_filename_or_reference>.
=item An array reference
If C<$input_filename_or_reference> is an array reference, each element in
the array must be a filename.
The input data will be read from each file in turn.
The complete array will be walked to ensure that it only
contains valid filenames before any data is uncompressed.
=item An Input FileGlob string
If C<$input_filename_or_reference> is a string that is delimited by the
characters "<" and ">" C will assume that it is an
I. The input is the list of files that match the
fileglob.
See L for more details.
=back
If the C<$input_filename_or_reference> parameter is any other type,
C will be returned.
=head3 The C<$output_filename_or_reference> parameter
The parameter C<$output_filename_or_reference> is used to control the
destination of the uncompressed data. This parameter can take one of
these forms.
=over 5
=item A filename
If the C<$output_filename_or_reference> parameter is a simple scalar, it is
assumed to be a filename. This file will be opened for writing and the
uncompressed data will be written to it.
=item A filehandle
If the C<$output_filename_or_reference> parameter is a filehandle, the
uncompressed data will be written to it. The string '-' can be used as
an alias for standard output.
=item A scalar reference
If C<$output_filename_or_reference> is a scalar reference, the
uncompressed data will be stored in C<$$output_filename_or_reference>.
=item An Array Reference
If C<$output_filename_or_reference> is an array reference,
the uncompressed data will be pushed onto the array.
=item An Output FileGlob
If C<$output_filename_or_reference> is a string that is delimited by the
characters "<" and ">" C will assume that it is an
I
