Digest::md5::file adds functionality for easy calculation of md5 checksums of entire files, directories or urls to the standard digest::md5 module.

example usage:

use digest::md5::file;
my $md5 = digest::md5->new;
$md5->addpath('/path/to/file.txt');
$md5->addpath(\@files);
$md5->adddir('/home/tmbg/');
$md5->addurl('http://www.tmbg.com/tour.html');
my $digest = file_md5_hex($file);
my $dir_hashref = dir_md5_hex($dir);
my $digest = url_md5_hex($url);
