+`gnus-summary-write-to-file', and `gnus-summary-write-body-to-file'.

+The value specifies an alternative function which appends, not
+overwrites, articles to a file. This implies that when saving many
+articles at a time, `gnus-prompt-before-saving' is bound to t and all
+articles are saved in a single file. This is meaningful only with
