-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
-has the same caption with \c '+' and \c '-' prefix, then these columns
-can be regarded as the values of an arc map.
+The \c \@edges is just a synonym of \c \@arcs.
 
 The \c \@attributes section contains key-value pairs, each line
-consists of two tokens, an attribute name, and then an attribute
-value. The value of the attribute could be also a label value of a
-node or an edge, or even an edge label prefixed with \c '+' or \c '-',
-which regards to the forward or backward directed arc of the
-corresponding edge.
