This automatically calls L<sync(2)> before the operation,
so that the maximum guest memory is freed.
+=item $equality = $h->equal ($file1, $file2);
+
+This compares the two files C<file1> and C<file2> and returns
+true if their content is exactly equal, or false otherwise.
+
+The external L<cmp(1)> program is used for the comparison.

=item $existsflag = $h->exists ($path);
This returns C<true> if and only if there is a file, directory
=item $h->mkfs ($fstype, $device);
This creates a filesystem on C<device> (usually a partition
-of LVM logical volume). The filesystem type is C<fstype>, for
+or LVM logical volume). The filesystem type is C<fstype>, for
example C<ext3>.
=item $h->mount ($device, $mountpoint);
