Rsync log file output

In order to find out what data will be modified/changed it is necessary to use: --itemize-change and --dry-run to find out what operations are going to be performed on the desired files.

The format for itemize-change is defined in the man page and more easily intepreted using the following table pulled from http://andreafrancia.it/2010/03/understanding-the-output-of-rsync-itemize-changes.html

YXcstpoguax  path/to/file
|||||||||||
`----------- the type of update being done::
 ||||||||||   <: file is being transferred to the remote host (sent).
 ||||||||||   >: file is being transferred to the local host (received).
 ||||||||||   c: local change/creation for the item, such as:
 ||||||||||      - the creation of a directory
 ||||||||||      - the changing of a symlink,
 ||||||||||      - etc.
 ||||||||||   h: the item is a hard link to another item (requires --hard-links).
 ||||||||||   .: the item is not being updated (though it might have attributes that are being modified).
 ||||||||||   *: means that the rest of the itemized-output area contains a message (e.g. "deleting").
 ||||||||||
 `---------- the file type:
  |||||||||   f for a file,
  |||||||||   d for a directory,
  |||||||||   L for a symlink,
  |||||||||   D for a device,
  |||||||||   S for a special file (e.g. named sockets and fifos).
  |||||||||
  `--------- c: different checksum (for regular files)
   ||||||||     changed value (for symlink, device, and special file)
   `-------- s: Size is different
    `------- t: Modification time is different
     `------ p: Permission are different
      `----- o: Owner is different
       `---- g: Group is different
        `--- u: The u slot is reserved for future use.
         `-- a: The ACL information changed

This schema is based on the contents of the rsync manual. 

By default the --log-file=log-file-name paramter will output the --itemize-change output
