## Installation

The easiest way to install CL-Photo is to use the Debian GNU/Linux operating system. You can then use the command `apt-get install cl-photo` to automatically download and install the CL-Photo package.

On a non-Debian system, you need to have ASDF installed to load the system definition file. You will need to change the source pathname in the system file to match the location where you have installed CL-Photo.
