551 command, and friends such as `gnus-summary-save-article-rmail'.
553 Gnus provides the following functions:
555 * gnus-summary-save-in-rmail (Rmail format)
556 * gnus-summary-save-in-mail (Unix mail format)
557 * gnus-summary-save-in-folder (MH folder)
558 * gnus-summary-save-in-file (article format)
559 * gnus-summary-save-body-in-file (article body)
560 * gnus-summary-save-in-vm (use VM's folder format)
561 * gnus-summary-write-to-file (article format -- overwrite)
562 * gnus-summary-write-body-to-file (article body -- overwrite)
563 * gnus-summary-save-in-pipe (article format)
565 The symbol of each function may have the following properties:
568 The value non-nil means save decoded articles. This is meaningful
569 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
570 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
571 `gnus-summary-save-in-pipe'.
574 The value specifies an alternative function which appends, not
575 overwrites, articles to a file. This implies that when saving many
576 articles at a time, `gnus-prompt-before-saving' is bound to t and all
577 articles are saved in a single file. This is meaningful only with
578 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
581 The value specifies the symbol of a variable of which the value
582 specifies headers to be saved. If it is omitted,
583 `gnus-save-all-headers' and `gnus-saved-headers' control what
584 headers should be saved."
