+This command copies the value stored at the `source` key to the `destination`
+key.
+
+By default, the `destination` key is created in the logical database used by the
+connection. The `DB` option allows specifying an alternative logical database
+index for the destination key.
+
+The command returns an error when the `destination` key already exists. The
+`REPLACE` option removes the `destination` key before copying the value to it.
+
+@return
+
+@integer-reply, specifically:
+
+- `1` if `source` was copied.
+- `0` if `source` was not copied.
+
+@examples
+
+```
+SET dolly "sheep"
+COPY dolly clone
+GET clone
+```
