+[[looping]]
+== Looping
+One common use case when working with Gremlin is to perform complex looping
statements using the `repeat()` step. While many of the common patterns for
looping within traversals are discussed in the documentation there are several
more complex patterns that include additional steps which are also commonly
used. This section attempts to demonstrate how to use some of these more
complex measurements.

graph depicted here:
+
+[gremlin-groovy]
+----
+g.addV().property(id, 'A').as('a').
+ addV().property(id, 'B').as('b').
+ addV().property(id, 'C').as('c').
+ addV().property(id, 'D').as('d').
+ addV().property(id, 'E').as('e').
+ addV().property(id, 'F').as('f').
+ addV().property(id, 'G').as('g').
+ addE('hasParent').from('a').to('b').
+ addE('hasParent').from('b').to('c').
+ addE('hasParent').from('d').to('c').
+ addE('hasParent').from('c').to('e').
+ addE('hasParent').from('e').to('f').
+ addE('hasParent').from('g').to('f').iterate()

+=== Conditional Looping with Max Depth
+
+One common situation encountered when writing `repeat()` loop is the need to
exit the loop when either a specific condition is met or a maximum depth is
reached. Given that graph above the following traversal demonstrates how to
accomplish this type of complex exit condition. In this example the traversal
will start at vertex A and loop through all outgoing edges until it reaches
vertex C or it until it has completed 3 loops.
Review comment:
"or it until it has completed 3 loops"
