++@cindex DateFormat, in CVSROOT/config

++Control the output format of dates from cvs. cvs version 1.12.x
++changed the default format to use ``iso8601'' dates, which are
++better for many reasons. However, old scripts/programs written to
++parse the output of various cvs commands (especially cvs log) may
++not cope with the change in date format (e.g. gcvs). The default
++value of DateFormat will be ``iso8601'', but if you need temporary
++backwards-compatibility set DateFormat=old.
