In the latest TUGboat (v38, no. 3) David Carlisle presented XII take II saying that the plain TeX file
xii.tex could be downloaded from https://ctan.org/pkg/xii. On going there one statement was that
xii was part of TeXlive, which I use. However
pdftex could not find
xii.tex so I ran
tlmgr to make sure that everything was uptodate.
xii.tex was neither downloaded or found. I then downloaded
xii.tex by hand but the contents were not the same as printed in TUGboat.
The original 1998
xii.tex was fascinating and I would like to try the take II
xii.tex version. Having tried the
tlmgr and manual download routes from CTAN, how do do I get it (and should the file names be different)?
