 This tool dumps and restores zookeeper state to/from a matching folder structure on disk.
 The server argument is mandatory then either a node to dump and where to dump it,
 or a previous dump to restore and the root to restore it to.

 usage: guano [-v] -s <zk_connect> [-d <znode> -o <folder>] [-r <znode-root> -i <folder>]

  -s,--server <arg>          *Required, the zookeeper remote server to connect to
                             i.e. "localhost:2181"
                             
  -d,--dump-znode <arg>      the znode to dump (recursively)
  -o,--output-dir <arg>      the output directory to which znode
                             information should be written (must be a
                             normal, empty directory)
                             
  -i,--input-dir <arg>       the input directory from which znode
                             information should be read
  -r,--restore-znode <arg>   the znode into which read data should be
                             restored

  -v,--verbose               enable debug output

  Note: When restoring you need to provide one level up as the node selected for the dump is included.
    e.g. java -jar target/guano-0.1a.jar -s "zookeeper-01.mydomain.com" -o "/tmp/zkdump" -d "/myroot"
         java -jar target/guano-0.1a.jar -s "zookeeper-01.mydomain.com" -i "/tmp/zkdump" -r "/"
