   As you can see, the first traversal removes vertices with the "name" field of "marko" and the second traversal verifies
  -that there are no vertices named "marko" after the first is executed.  After seeing success like that in the console
  +that there are no vertices named "marko" after the first is executed.  After seeing success like that in the console,
   it is all too tempting to copy and paste that line of code to a Java class like:

negative.code: link:http://groups.google.com/group/gremlin-users[Gremlin Users mailing list] about a traversal that you are having
  trouble with in your application, try to convert the gist of it to one of the toy graphs.  Taking this step will make it
  easier for advanced Gremlin users to help you, which should lead to a faster response time for your problem. In
  addition, there is the added benefit that the mailing list post will likely be more relevant to other users, as it is
  not written solely in the context of your domain.
  
  [[help]]
  As you get familiar with the console, it is good to know what some of the basic commands are. A "command" is not
  "Gremlin code", but something interpreted by the console to have special meaning in terms of configuring how the
  console works or performing a particular function outside of code itself.  These commands are itemized in the
  link:http://tinkerpop.apache.org/docs/x.y.z/reference/#_console_commands[reference documentation], but they can also
  be accessed within the console itself with the `:help` command.
