+===== Production operators =====
+Production operators are operators that can be used in a production statement.
+==== Edge operators ====
+| whitespace | add node and connect with previous node, if any, by a successor edge |
+| > | connect node with previous by a successor edge |
+| < | connect node with previous by a reverse successor edge |
+| %%<->%% | connect node with previous by successor edges in both directions |
+| %%---%% | connect node with previous by a successor edge if there does not yet exist such an edge in either direction |
+| %%+>%%, %%<+%%, %%<+>%%, %%-+-%% | as before, but branch instead of successor edges |
+| %%/>%%, %%</%%, %%</>%%, %%-/-%% | as before, but refinement instead of successor edges |
+| %%-e->%%, %%<-e-%%, %%<-e->%%, %%-e-%% with an int-valued expression e | as before, but edges of type e instead of successor edges |
+| %%-n->%% with a node-valued expression n | create a compound edge with n encoding the edge data |
+| %%<-n-%% with a node-valued expression n | as before, but reverse direction |
+| [, ] | define the starts and the end of a branch connected subgraph |
