** Flyspell
Flyspell offers on-the-fly spell checking. We can enable flyspell for all
text-modes with this snippet.
#+begin_src emacs-lisp
(add-hook 'text-mode-hook 'turn-on-flyspell)
#+end_src
To use flyspell for programming there is =flyspell-prog-mode=, that only
enables spell checking for comments and strings. We can enable it for all
programming modes using the =prog-mode-hook=.

=flyspell= signals an error if there is no spell-checking tool is installed.
We can advice =turn-on-flyspell= and =flyspell-prog-mode= to only try to
enable =flyspell= if a spell-checking tool is available. Also we want to
enable cycling the languages by typing =C-c l=, so we bind the function
returned from =cycle-languages=.
We enable =flyspell-mode= for all text-modes, and use =flyspell-prog-mode=
for spell checking comments and strings in all programming modes. We bind
=C-c l= to a function returned from =cycle-languages=, giving a language
switcher for every buffer where flyspell is enabled.
