LaTeX2e class for submission to the scientific journal Astronomy and Astrophysics. In order to ensure the smoothest transition for both authors and publishers, Springer-Verlag has kindly granted EDP Sciences the permission to use the LaTeX macro package that they developed for A&A Main journal. Only minor changes have been incorporated between the Springer class (1999) and the EDP Sciences class for the new journal. WWW: http://www.edpsciences.org/
