- ?on_mintstamp obj
- # on_mintstamp present and not empty list: provides a
- # script which returns the current mintstamp. This
- # means entries start with a 16-hex-digit signed
- # integer known as a tstamp; occasionally,
- # on_mintstamp will be called and then entries whose
- # tstamp is < mintstamp will be deleted automatically.
+ ?on_lexminval obj
+ # on_lexminval present and not empty list: provides a
+ # script which returns the current lexminval. In
+ # this case, occasionally,
+ # on_lexminval will be called and then entries whose
+ # value is lexically strictly less than lexminval
+ # will be deleted automatically. The comparison
+ # is bytewise on the UTF-8 representations.
