NAME
       PerlIO::via::Bzip2 - PerlIO layer for Bzip2 (de)compression

SYNOPSIS
	   use PerlIO::via::Bzip2;
	   # or
	   use PerlIO::via::Bzip2 level	=> 9; #	Maximum	compression

	   # Read a bzip2 compressed file from disk.
	   open(my $fh,	"<:via(Bzip2)",	"compressed_file");
	   my $uncompressed_data = <$fh>;

	   # Compress data on-the-fly to a bzip2 compressed file on disk.
	   open(my $fh,	">:via(Bzip2)",	"compressed_file");
	   print {$fh} $uncompressed_data;

	   # Set compression level
	   PerlIO::via::Bzip2->level(5);
	   open(my $fh,	">:via(Bzip2)",	"compressed_file");
	   print {$fh} $uncompressed_data;

DESCRIPTION
       This module implements a	PerlIO layer which will	let you	handle bzip2
       compressed files	transparently.

   Class Methods
       level([$level])
	   level sets or returns the compression level of the bzip2 library.
	   It ranges from 1 (least compression,	most efficient memory use) to
	   9 (best compression,	most memory usage).

	   This	parameter can also be set during using library import, using
	   "use	PerlIO::via::Bzip2 level => $level".

BUGS
       Using binmode() on an opened file for compression will pop (remove) the
       layer.

PREREQUISITES
       This module requires Compress::Bzip2 version 1.03.
