+Digest::base - Digest base class
+
+=head1 SYNOPSIS
+
+  package Digest::Foo;
+  use base 'Digest::base';
+
+=head1 DESCRIPTION
+
+The C<Digest::base> class provide implementations of the methods
+C<addfile> and C<add_bits> in terms of C<add>, and of the methods
+C<hexdigest> and C<b64digest> in terms of C<digest>.
+
+Digest implementations might want to inherit from this class to get
+this implementations of the alternative I<add> and I<digest> methods.
+A minimal subclass needs to implement the following methods by itself:
+
+    new
+    clone
+    add
+    digest
+
+The arguments and expected behaviour of these methods are described in
+L<Digest>.

+=head1 NAME
+
+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.
