NAME

       IO::Digest - Calculate digests while reading or writing

SYNOPSIS

	use IO::Digest;

	# Get a Digest::MD5 object that takes input while $fh being written or read
	$iod = IO::Digest->new ($fh, 'MD5');

	print $fh "fooo";
	print $iod->hexdigest

DESCRIPTION

       This module allows you to calculate digests while reading or writing file handles.  This avoids the case you need to reread the same con-
       tent to compute the digests after written a file.
