An example of the syntax, from a version of Dijkstra's algorithm[0]:
The current node is a node that varies.
A node can be found, examined, or unreached.
A node has a number called the total distance.
Definition: a node is near if its total distance is 10 or less.
Following relates various nodes to one node (called the precedent).
The verb to follow (he follows, they follow, he followed, it is followed, he is following) implies the following relation.
