20  * <p>
21  * Suppose as a result of performing a command the CVS server responds
22  * as follows:<br>
23  * <pre>
24  * [...]
25  * Copy-file myproject/ \n
26  * /u/cvsroot/myproject/oldfile.txt \n
27  * newfile.txt
28  * [...]
29  * </pre>
30  * Then we copy (or optionally rename) the local file "oldfile.txt" in
31  * folder "myproject" to "newfile.txt". This response is used to create
32  * a backup copy of an existing file before merging in new changes.
