   Specifies one or more generations of an element to be retrieved
   from the library. An element expression can be an element name, a
   group name, a wildcard expression, or a list of these separated by
   commas. By default, the most recent generation on the main line of
   descent is fetched.

   with this command, usually used to explain why the command was
   entered. The remark is enclosed in quotation marks. If no remark
   was entered, a null remark ("") is logged.
