[Xy-pic] tilted ~

[Michael Barr]

I tried to add
\usepackage[arrow,pdf]{xy}
and \pdfoutput1
to my file as suggested by Daniel Müllner and got the following messages:

No pages of output.

Note that this version of xy-pic is dated 1999.  But it is what came with 
Miktex 2.8 (version of 2010) since I used a clean installation from a 
TeX-Live CD on a new computer.  My User's guide and Reference Manuals are 
also dated 1999 and refer to v. 3.7, the one I am using, and does not 
mention a pdf option.  There is a dvips option but when I tried that, the 
output consisted only of the nodes A and B.

Next I went to CTAN and found that the current version is 3.11 (obviously, 
the Miktex program has not caught up with this).  I downloaded the zip 
file and unzipped it, but there is no automatic installation program and 
the instructions, at least for a Windows user, are not at all obvious. 
Also I am afraid to install over the old installation.  So I copied the 
file xypic.tex to the directory that contains things like xyarrow.tex and 
tried the option pdf.  That still resulted in the error message "No pdf@@@ 
option".  Finally I tried adding dvipdf.tex to my working directory and 
simply inputting it.  That resulted in no error message, but the diagram 
was in no way improved.
