@L: Set language

@Ll sets the language to l, where l is one of {c,c++,n,n9,r,r9,v,x}. See Languages.

There are shorthand forms of this command for some languages; see @c (ATc), @c++ (ATcpp), @n (ATn), @n9 (ATn9), @r (ATr), and @r9 (ATr9).

Generally, the global language should be set in the limbo section by means of @L, @c, etc. rather on the command line by options such as -L or -c.
