 		The \c \@edges is just a synonym of \c \@arcs. The \@arcs section can

 		can be regarded as the values of an arc map.
 		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.
