+    (description
+     "This package defines macros for drawing Feynman graphs in LaTeX documents.
+It is an important update of the @code{axodraw} package, but since it is not
+completely backwards compatible, we have given the style file a changed name.
+
+Many new features have been added, with new types of line, and much more
+flexibility in their properties.  In addition, it is now possible to use
+@code{axodraw2} with pdfLaTeX, as well as with the LaTeX-dvips method.
+However with pdfLaTeX (and also LuaLaTeX and XeLaTeX), an external program,
+@command{axohelp}, is used to perform the geometrical calculations needed for
+the pdf code inserted in the output file.  The processing involves a run of
+@command{pdflatex}, a run of @command{axohelp}, and then another run of
+@command{pdflatex}.")
