CAVEATS
-------
-The first form doesn't allow yet to overwrite an existing file
-(whether it could be recovered from Git or not), and the second form
-does not check before overwriting any file, possibly leading to loss
-of non-committed modifications.
+This command does not allow yet to overwrite an existing file (whether
+it could be recovered from Git or not). Further more, when copying a
+directory, the second form does not allow to proceed if a directory by
+that name already exists inside the target, even when no file inside
+that directory would be overwritten.
