+defines a command @code{\\footcite} which is similar to the LaTeX
+@code{\\cite} command but the references cited in this way appear at the
+bottom of the pages.  This @code{foot} bibliography does not conflict with the
+standard one and both may exist simultaneously in a document.  The command
+@code{\\cite} may still be used to produce the standard bibliography.  The
+@code{foot} bibliography uses its own style and bibliographic database which
+may be specified independently of the standard one.  Any standard bibliography
+style may be used.")
