[Xy-pic] diagxy

[Michael Barr]

Some of you will be familiar with my 15 (or so) year old diagram macros.
I recently decided to reimplement them as a front-end to xy-pic.  This has
now been done and I have placed the results on ctan.  I forget the exact
directory, but if you search for diagrams and then my name, you will find
them.  A slightly upgraded version can be found in
ftp.math.mcgill.ca/pub/barr.  The file is diagxy.zip and I also recommend
that you capture derfun.tex to see them in use.  That location will always
contain the most recent version.
