548 * gnus-summary-save-in-mail (Unix mail format)
549 * gnus-summary-save-in-folder (MH folder)

554 * gnus-summary-write-body-to-file (article body -- overwrite)

558 * :decode
559 The value non-nil means save decoded articles. This is meaningful
560 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
561 `gnus-summary-write-to-file', and `gnus-summary-write-body-to-file'.
563 * :function
564 The value specifies an alternative function which appends, not
565 overwrites, articles to a file. This implies that when saving many
566 articles at a time, `gnus-prompt-before-saving' is bound to t and all
567 articles are saved in a single file. This is meaningful only with
568 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
570 * :headers
571 The value specifies the symbol of a variable of which the value
572 specifies headers to be saved. If it is omitted,
573 `gnus-save-all-headers' and `gnus-saved-headers' control what
574 headers should be saved."

593 The recommended coding systems are `utf-8', `iso-2022-7bit' and so on,
594 which can safely encode any characters in text. This is used by the
595 commands including:
597 * gnus-summary-save-article-file
598 * gnus-summary-save-article-body-file
599 * gnus-summary-write-article-file
600 * gnus-summary-write-article-body-file

605 * gnus-summary-save-body-in-file
606 * gnus-summary-write-to-file
607 * gnus-summary-write-body-to-file

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

668 from the buffer of the article to be saved with the newsgroup as the
669 parameter. If it is a list, it will be evaled in the same buffer.
