  NOTE: If the above plugins are not loaded then they will need to be enabled or else certain examples will not work. If using the standard Gremlin Console distribution, then the plugins should be enabled by default.  See below for more information on the `:plugin use` command to manually enable plugins. These plugins, with the exception of `tinkerpop.tinkergraph`, cannot be removed from the Console as they are a part of the `gremlin-console.jar` itself.  These plugins can only be deactivated.
  
  The Gremlin Console is loaded and ready for commands. Recall that the console hosts the Gremlin-Groovy language.  Please review link:http://groovy.codehaus.org/[Groovy] for help on Groovy-related constructs. In short, Groovy is a superset of Java. What works in Java, works in Groovy. However, Groovy provides many shorthands to make it easier to interact with the Java API.  Moreoever, Gremlin provides many neat shorthands to make it easier to express paths through a property graph.
