543 The function will be called by way of the `gnus-summary-save-article'

546 Gnus provides the following functions:
548 * gnus-summary-save-in-rmail (Rmail format)

550 * gnus-summary-save-in-folder (MH folder)

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