-/***this code parse the synclist file generated by rsync in dry-run mode.
-    The minimum options for rsync is : -avW --dry-run --delete 
-    e.g.
-   /usr/local/bin/rsync --rsync-path=/usr/local/bin/rsync 
-   -avW --dry-run --delete  
-   /src/path/ dest_machine:/target/path/ > output 2>&1
-A typical output of rsync may look like this:
-Client is very old version of rsync, upgrade recommended.
-building file list ... done
-xyz -> ./sub1/xyz
-file1
-fn
-fn1
-j
-sub1/hardlink_to_file1
-sub1/path/testfile
-sub1/xyz
-sent 337 bytes  read 44 bytes  254.00 bytes/sec
-total size is 320751046  speedup is 841866.26
-
-This code does the following three things.
-(1) skip the lines before 'done' and after 'wrote'
-(2) output all directories and file_path
-    e.g
-    for an entry: sub1/path/testfile, the output is
-      sub1
-      sub1/path
-      sub1/path/testfile
-(3) xyz -> ./sub1/xyz
-    the output is 
-       xyz
-(4) If file1 and sub1/hardlink are hardlinked
-    the output is 
-       file1
-       sub1/hardlink file1
-   
-For the example output above, the output of this code is:
-
-xyz
-file1
-fn
-fn1
-j
-sub1
-sub1/hardlink_to_file1 file1
-sub1/path
-sub1/path/testfile
-sub1/xyz

-/*** (a)
-     get those softlinks that points to a directory 
-     this is to deal with the following scenario
-     previous structure
-         dir_path  (a directory)
-         db        (a directory)
-
-     newly updated structure on master
-         dir_path -> db
-         db
-
-     rsync --dry-run generates
-        dir_path -> db                      [a link is done on target]
-        deleting dir_path/sub/filename1     [wrong file gets removed ]
-	deleting dir_path/sub/filename2...
-
-     file_operations.c does this when dir_path -> db is due
-        delete dir_path (rm -rf)
-        make the softlink
-     But then the following delete will have undesired deletion.
