Spell check a directory from emacs

[christian . place]

Hi,

is it possible to have emacs and ispell to spell check all (TeX) files
in a directory? I want to spell check every file in a directory using
emacs instead of using the command line ispell. I could of course open
every file in emacs and then spell check them one by one, by calling
spell-check-buffer on each file, but if it is possible to call
spell-check only once.

Thanks for any answers in advance,
