+ sparse filename size
+
+This creates an empty sparse file of the given size, and then adds
+so it can be further examined.
+
+In all respects it works the same as the C<alloc> command, except that
+the image file is allocated sparsely, which means that disk blocks are
+not assigned to the file until they are needed.  Sparse disk files
+only use space when written to, but they are slower and there is a
+danger you could run out of real disk space during a write operation.
+
+For more advanced image creation, see L<qemu-img(1)> utility.
