------------------------------------------------------------------------------

The xypdf package improves the output quality of the Xy-pic package when PDF
documents are generated. It produces generic PDF code for graphical elements
like lines, curves and circles instead of approximating these elements with
glyphs in special fonts as the original Xy-pic package does. The xypdf package
works with both TeX and LaTeX in the occurrences of pdfTeX, XeTeX and eTeX
with dvipdfm(x) to generate PDF files.

The xypdf package is being integrated and distributed together with Xy-pic,
starting with Xy-pic version 3.8. Since xypdf is now a “driver” and not a
“LaTeX package” in technical terms, the file “xypdf.sty” has become obsolete
and is now just a wrapper for “xypdf.tex”. You do not need to install the file
“xypdf.sty” or xypdf as a separate package. Instead, make sure that you have
Xy-pic version 3.8 or later, and the PDF driver will be included.

The current version of Xy-pic with xypdf can be found at
