Interpreting output from rsync

[Suresh Govindachar]

Hello,

  In regard to output, rsync has the following features:  
  
      a) -v option with various levels of verbosity 
      b) --stats 
      c) --log-file=foo 
      d) messages rsync prints to stdout 
      e) messages rsync prints to stderr. 

  Where can I find an explanation of the format, content
  and interpretation of the outputs (a-e)?

  Thanks,
