Documentation:
Alist mapping languages to their listing language counterpart.
The key is a symbol, the major mode symbol without the "-mode".
The value is the string that should be inserted as the language
parameter for the listings package. If the mode name and the
listings name are the same, the language does not need an entry
in this list - but it does not hurt if it is present.

You can customize this variable.
