anchor.diff:  We recommend the http://eclipse.org/m2e/[m2eclipe] eclipse plugin when working with
   eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
   marketplace".
  +
  +Once the projects are imported into Eclipse you will also need to tell m2eclipse
  +to use the `.settings.xml` file for the projects.  If you do not do this you may
  +see errors many different errors related to the POMs in the projects.
  +Open your Eclipse preferences, expand the Maven preferences, and select User Settings.
  +In the User Settings field click Browse and navigate to the Spring Cloud project you
  +imported selecting the `.settings.xml` file in that project.  Click Apply and then OK to
  +save the preference changes.

  === Terminology
  
  Spring Cloud Sleuth borrows http://research.google.com/pubs/pub36356.html[Dapper's] terminology.
  
  *Span:* The basic unit of work. For example, sending an RPC is a new span, as is sending a response to an RPC. Span's are identified by a unique 64-bit ID for the span and another 64-bit ID for the trace the span is a part of.  Spans also have other data, such as descriptions, key-value annotations, the ID of the span that caused them, and process ID's (normally IP address).
  
  Spans are started and stopped, and they keep track of their timing information.  Once you create a span, you must stop it at some point in the future.
  
  *Trace:* A set of spans forming a tree-like structure.  For example, if you are running a distributed big-data store, a trace might be formed by a put request.
