Runestone documentation: adding books

[Sean Fitzpatrick]

I decided to experiment with adding an existing Runestone book on my Runestone test server.

Following the instructions at https://runestoneserver.readthedocs.io/en/latest/docker/README.html#add-books

 I ran 'rsmanage build thinkcspy --clone https://github.com/RunestoneInteractive/thinkcspy.git'

but this just resulted in what appears to be the help page for rsmanage.

So I conclude that this method is perhaps no longer supported.

Since this book is now written in PreTeXt, I think the right approach is probably to first clone the book repository into the books folder, and then use the rsmanage build --ptx command?

When I tried doing it this way, I get quite a few PTX errors about exercises that lack a structure number, but the html build succeeds.

Course creation fails because the document id is httlacs and not thinkscpy, but if I rename the cloned folder from thinkcspy to httlacs and build httlacs, it seems to work OK.
