+# The file should contain exactly two sections: router and link, each starting with the corresponding keyword
+#
+# router section defines topology nodes and their relative positions (e.g., to use in visualizer)
+router
+
+# each line in this section represents one router and should have the following data
+# node  comment     yPos    xPos

+# Note that `node` can be any string. It is possible to access to the node by name using Names::Find, see examples.
+
+# link section defines point-to-point links between nodes and characteristics of these links
+link
+
+# Each line should be in the following format (only first two are required, the rest can be omitted)
+# srcNode   dstNode     bandwidth   metric  delay   queue
+# bandwidth: link bandwidth
+# metric: routing metric
+# delay:  link delay
+# queue:  comma-separated list, specifying class for Queue (on both sides of the link) and necessary attributes
+# error:  comma-separated list, specifying class for ErrorModel and necessary attributes
