You can use Aspell as an orthographic corrector directly
in jPreTeX.
In order to do this you start the corrector by
clicking on the corrector jPreTeX
button.
jPreTeX has by default the French and the
English dictionnaries, you can install any other you
like in the directory
../jaPreTeX/Aspell/dict/
these dictionnaries are free programs working on
Windows, MacIntosh and Unix.
A change of language is
automatically noticed by Aspell
and the language is the one you choose by the menu commands
Preferences->jPreTeX
Preferences
then you choose "Langue du Texte" in the
combo box.
If there is a misspelling, the corrector
button
changes and you have a list of proposed corrections in red in the status bar at
the bottom of the screen.
