The above keyword string should be followed by `latex-mode' or
`nroff-mode' to put the current buffer into the desired parsing mode.

Extended character mode can be changed for this buffer by placing
a `~' followed by an extended-character mode -- such as `~.tex'.
The last occurring definition in the buffer will be used.
