562 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
563 `gnus-summary-save-in-pipe'.
566 The value specifies an alternative function which appends, not
567 overwrites, articles to a file. This implies that when saving many
568 articles at a time, `gnus-prompt-before-saving' is bound to t and all
569 articles are saved in a single file. This is meaningful only with
570 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
573 The value specifies the symbol of a variable of which the value
574 specifies headers to be saved. If it is omitted,
575 `gnus-save-all-headers' and `gnus-saved-headers' control what
576 headers should be saved."
