stephen mallette closed TINKERPOP-1840.
    Resolution: Invalid

I did make a change with respect to this as mentioned in the comments. It 
seemed sufficient in my mind and no additional information/feedback was 
provided so I'm going to close this now. I'm marking it as "invalid" only 
because the change was quite minor and was performed on a release that is now 
official - we wouldn't want this issue to show up on future release notes.

>                 Key: TINKERPOP-1840
>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1840
>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: documentation
>    Affects Versions: 3.3.0
>         Environment: Apache Tinkerpop 3.3, Gremlin documentation
>            Reporter: Suhas Udeda
>            Priority: Minor
> In the recipes section of Apache Tinkerpop web page, there is section 
> dedicated to computing the maximum depth of a node in a graph. According to 
> the command given there, maximum depth is includes the current node in its 
> count as well. While this is working fine for all the nodes, it fails when it 
> comes to the leaf nodes; it returns garbage value. This happens because of 
> the placement of emit() function in that command.
> When I tried understanding how emit() function works, I could not find a 
> section dedicated to this function in the documentation. I believe this is a 
> shortcoming especially when beginners are trying to understand the 
> functionality by referring the documentation. It would be nice if a section 
> can be added for emit() and other such functions which lack their 
> representation in the documentation.
