automatic dictionary switcher for Emacs spell checking

 Auto-dictionary is a minor mode that hooks into Flyspell's on-the-fly spell
 checking and extends these checks to also detect language. Auto-dictionary
 then sets 'ispell-dictionary' to use the detected language. This package is
 useful for bilingual and multilingual Emacs users.
 .
 Language detection is per buffer (per document), and auto-dictionary will
 choose the language whose words appear most frequently in a document. If that
 document also contains a second language, and then the document is edited until
 there are a greater number of words from the second language, then
 auto-dictionary will choose the second language. That is to say,
 auto-dictionary's pick always depends on the current state of the document, and
 it will only pick one language. This package does not enable multiple
 dictionary support for Emacs ispell.
 .

   * ca - Catalan

   * de - Deutsch (German)
