+     "This package enables automated citation with BibTeX for legal studies
+and the humanities.  In addition, the package provides commands for specifying
+editors in a commentary in a convenient way.  Simplified formatting of the
+citation as well as the bibliography entry is also provided.  It is possible
+to display the (short) title of a work only if an authors is cited with
+multiple works.  Giving a full citation in the text, conforming to the
+bibliography entry, is supported.  Several options are provided which might be
+of special interest for those outside legal studies--for instance, displaying
+multiple full citations.  In addition, the format of last names and first
+names of authors may be changed easily.  Cross references to other footnotes
+are possible.  Language dependent handling of bibliography entries is possible
+by the special language field.")
