559 Gnus provides the following functions:
561 * gnus-summary-save-in-rmail (Rmail format)
562 * gnus-summary-save-in-mail (Unix mail format)
563 * gnus-summary-save-in-folder (MH folder)

575 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
576 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
577 `gnus-summary-save-in-pipe'.
579 * :function
580 The value specifies an alternative function which appends, not
581 overwrites, articles to a file. This implies that when saving many
582 articles at a time, `gnus-prompt-before-saving' is bound to t and all
583 articles are saved in a single file. This is meaningful only with
584 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
586 * :headers
587 The value specifies the symbol of a variable of which the value
588 specifies headers to be saved. If it is omitted,
589 `gnus-save-all-headers' and `gnus-saved-headers' control what
590 headers should be saved."

612 commands including:
614 * gnus-summary-save-article-file
615 * gnus-summary-save-article-body-file
616 * gnus-summary-write-article-file

622 * gnus-summary-save-body-in-file
623 * gnus-summary-write-to-file
624 * gnus-summary-write-body-to-file

627 buffer to a file if the value of this variable is non-nil. Note that
628 buttonized MIME parts will be lost in a saved file in that case.

684 article. If the match is a symbol, that symbol will be funcalled
685 from the buffer of the article to be saved with the newsgroup as the
686 parameter. If it is a list, it will be evaled in the same buffer.
