     1  # This datadriven test uses a single command 'build' that illustrates a sequence
     2  # of calls to a fragmenter.
     3  #
     4  # 'add' lines add a new span with the provided sequence number and the provided
     5  # bounds. 'add' outputs nothing.
     6  #
     7  # 'deleted' lines test whether the provided key is deleted by a RANGEDEL in the
     8  # fragmenter when read at the trailing snapshot sequence number.
