JaxoDraw-2.0 uses a new LaTeX style file called axodraw4j.sty (i.e. 'axodraw for JaxoDraw') for its LaTeX exports which is based on J. Vermaseren's original axodraw.sty. The name has been changed to avoid any backward compatibility issues with olddocuments that use the original axodraw.sty.
Documentation of axodraw4j is included in the distribution tar ball. The latest version of the docs is always available from our subversion repository. An appendix with a detailed description has been published in the release notes of JaxoDraw-2.0, Comput. Phys. Commun. 180, 1709 (2009) .
