    81 The \c \@edges is just a synonym of \c \@arcs. The @arcs section can
    82 also store the edge set of an undirected graph. In such case there is
    83 a conventional method for store arc maps in the file, if two columns
    84 has the same caption with \c '+' and \c '-' prefix, then these columns
    85 can be regarded as the values of an arc map.
     81The \c \@edges is just a synonym of \c \@arcs.

    8783The \c \@attributes section contains key-value pairs, each line
    88 consists of two tokens, an attribute name, and then an attribute
    89 value. The value of the attribute could be also a label value of a
    90 node or an edge, or even an edge label prefixed with \c '+' or \c '-',
    91 which regards to the forward or backward directed arc of the
    92 corresponding edge.
