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

543 Gnus provides the following functions:
545 * gnus-summary-save-in-rmail (Rmail format)
546 * gnus-summary-save-in-mail (Unix mail format)
547 * gnus-summary-save-in-folder (MH folder)

557 * :decode
558 The value non-nil means save decoded articles. This is meaningful
559 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
560 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
561 `gnus-summary-save-in-pipe'.
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."

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

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

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

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