How can I change the language in Emacs when using ispell?

Question

I would like to use the ispell-buffer command in Emacs. It uses the english language by default. Is there an easy way to switch to another dictionary (eg another language)?

Answer 1

From the file ispell.el you may specify some options for the ispell commands. This happens by adding a section to the end of your file like this:

;; Local Variables:
;; ispell-check-comments: exclusive
;; ispell-local-dictionary: "american"
;; End:

Note the double semicolon marks the start of comments in the current mode. It should probably be changed to reflect the way your file (programming language) introduces comments, like // for Java.
