news-inews-program (which is "/usr/local/inews").
+Before you override a variable this way, *look at the value* that the

+variable should have. If you don't pay attention to what you are

Note that, on some systems, the code you place in site-init.el must
not use expand-file-name or any other function which may look
something up in the system's password and user information database.
