Changes in 0.1.1:

* Presence of `.image-garden.mk` file is now correctly reflected in dependencies
  of the `*.user-data` files, so that editing the local makefile automatically
  causes all the disk images to become outdated.

* Using `image-garden make -B` should no longer re-download everything, as
  `wget` is now called with `--no-clobber` and is smart enough to notice that
  re-downloading complete images is not required.

* Image garden now comes with a manual page. See `man image-garden` to learn about
  all the documented features.

* Oracle Cloud release 8 is now supported.

* SSH service is configured with "UsePAM yes" by default.

Changes in 0.1:

 * Initial release.
