[oXygen-user] where's Saxon?

[Syd Bauman]

Sometimes I want to execute some XSLT (2.0) transformations from the
(Mac OS X) command-line. In the past, I've just issued
  java -jar /Applications/oxygen/lib/saxon9.jar [buncha args here]
but that no longer works, as the file saxon9.jar does not exist in
the current release of oXygen. But what replaces it? I tried what
seemed (to me) likely, saxon9sa.jar, but got the error message 
  "Failed to load Main-Class manifest attribute ..."

Any thoughts?
