+
+Digest::file - Calculate digests of files
+
+=head1 SYNOPSIS
+
+  # Poor mans "md5sum" command
+  use Digest::file qw(digest_file_hex);
+  for (@ARGV) {
+      print digest_file_hex($_, "MD5"), "  $_\n";
+  }
+
+=head1 DESCRIPTION
+
+This module provide 3 convenience functions to calculate the digest
+of files.  The following functions are provided:
+
+=over
+
+=item digest_file( $file, $algorithm, [$arg,...] )
+
+This function will calculate and return the binary digest of the bytes
+of the given file.  The function will croak if it fails to open or
+read the file.
+
+The $algorithm is a string like "MD2", "MD5", "SHA-1", "SHA-512".
+Additional arguments are passed to the constructor for the
+implementation of the given algorithm.
+
+=item digest_file_hex( $file, $algorithm, [$arg,...] )
+
+Same as digest_file(), but return the digest in hex form.
+
+=item digest_file_base64( $file, $algorithm, [$arg,...] )
+
+Same as digest_file(), but return the digest as a base64 encoded
+string.
