An addendum to my note re M Barr's diagxy package: I just noticed that
there is a similarly named file 

    ftp://ftp.math.mcgill.ca/pub/barr/DIAGXY.ZIP

(the difference being uppercase vs lower case) which is a few days
more recent - I suggest browsing the directory 

    ftp://ftp.math.mcgill.ca/pub/barr/

to see which one is more recent than the other in future, since I
imagine the name distinction reflects the method of uploading the file
rather than any content distinction.
