+These are four standard functions; three of them move messages to an archive
folder in the specified way. This means old messages can be compressed
and saved in a file, being deleted from the original folder.
+The last one divides messages to some MH folders.
@table @code
@item wl-expire-archive-number1
@code{$folder-199812;zip}. The name of the archiving folders except the
date part are determined in the same way as
@code{wl-expire-archive-number1}.
-@end table

You can set the first argument to these three standard functions to non-nil
in @code{wl-expire-alist} so as to retain message numbers in the folder.
If you omit the argument, consecutive numbers from 1 are assigned for
each archiving folder.
