        return <<-EOF
Get the splits of the named table:
  hbase> get_splits 't1'
  hbase> get_splits 'ns1:t1'

The same commands also can be run on a table reference. Suppose you had a reference
t to table 't1', the corresponding command would be:

  hbase> t.get_splits
EOF
      end

      def command(table)
        get_splits(table(table))
      end

      def get_splits(table)
        table._get_splits_internal()
      end
    end
  end
end
