(defcustom TeX-output-view-style
  '(("^dvi$" ("^a5$" "^landscape$") "xdvi \"%d\" -paper a5r -s 4")
    ("^dvi$" "^a5$" "xdvi \"%d\" -paper a5")
    ("^dvi$" ("^landscape$" "^pstricks$\\|^psfrag$")
                        "dvips -t landscape -f \"%d\" | gv")
    ("^dvi$" "^landscape$" "xdvi \"%d\" -paper a4r -s 4")
    ("^dvi$" "^pstricks$\\|^psfrag$" "dvips -f \"%d\" | gv")
    ("^dvi$" "." "xdvi \"%d\"")
    ("^pdf$" "^landscape$" "xpdf -papertype a4r \"%o\"")
    ("^pdf$" "." "xpdf \"%o\"")
    ("^html?$" "." "netscape \"%o\""))
  "List of output file extensions and view options.

So this tells that if you generated a .dvi file it views with xdvi, but if
you generated a .pdf file, it views with xpdf. And then as you can see it
is also parameterized with options and packages.

If you use LaTeX PDF rather than LaTeX it knows that the output file was
.pdf rather than .dvi. 

Please note that this is still not fixed in stone, i.e. we might come up
with a more flexible and easier to use system if someone has a bright
idea. For example the options and packages now easily lead to a
combinatorial explosion. So an easier system to build up the commands from
parts might be preferable.
