Original cmucl design pdf is missing
The link to the original cmucl design doc pdf is broken. However, cmucl.org has a copy.
Perhaps we need to add the pdf file (from cmucl.org) to this repo. Or add the original TeX files here so the we rebuild it if necessary.
I also found out that the old versions of the user manual don't exist here either, but do on cmucl.org. Actually any of the links to the old docs are missing.
I think we should preserve these old docs here as well as on cmucl.org since cmucl.org gets the files from here.
