Prepare to iterate releases.
Configure the experimental pathname.
The experimental pathname stuffer needs to have an easily changeable path. I have used the ubiquitous system to configure other pathname options in the past, so I use it again.
(ql:quickload 'ubiquitous)
(setf (ubiquitous:value :sdl-last) #P"your-pathname")
You will set this value to the pathname of the combined directory once the example distribution is prepared.
