 The \c \@edges is just a synonym of \c \@arcs. The \@arcs section can
 also store the edge set of an undirected graph. In such case there is
 a conventional method for store arc maps in the file, if two columns
-have the same caption with \c '+' and \c '-' prefix, then these columns
+has the same caption with \c '+' and \c '-' prefix, then these columns
 can be regarded as the values of an arc map.
