Ex_08 – -checkcell
� An optional argument that specifies the path of a checkcell file.
� This file contains the list of cells to check for differences;
dbdiff then checks only the specified cells.
� If you know that modification has been done in particular cells,
you can specify those changed cell names in a file and use this option.
� This speeds up the operation of dbdiff by allowing it to look for differences
in some of the cells rather than all of the cells.
