  10 # It's quite possible that the user might specify the same source file
  11 # more than once on the command line, perhaps through shell variables
  12 # or wildcard expansions.  It might cause problems for rsync if the
  13 # same name occurred more than once in the file list, because we might
  14 # be trying to update the first copy and generate checksums for the
  15 # second copy at the same time.  See clean_flist() for the implementation.
  16
  17 # We don't need to worry about hardlinks or symlinks.  Because we
  18 # always rename-and-replace the new copy, they can't affect us.
