818 | Each function takes two threads and returns non-nil if the first |
819 | thread should be sorted before the other. If you use more than one | |
820 | function, the primary sort function should be the last. You should | |
821 | probably always include `gnus-thread-sort-by-number' in the list of | |
822 | sorting functions -- preferably first. Also note that sorting by date | |
823 | is often much slower than sorting by number, and the sorting order is | |
824 | very similar. (Sorting by date means sorting by the time the message | |
825 | was sent, sorting by number means sorting by arrival time.) | |

827 | Each list item can also be a list `(not F)' where F is a |
828 | function; this specifies reversed sort order. | |
