538 "A function to save articles in your favourite format.
539 The function will be called by way of the `gnus-summary-save-article'
540 command, and friends such as `gnus-summary-save-article-rmail'.
542 Gnus provides the following functions:
544 * gnus-summary-save-in-rmail (Rmail format)
545 * gnus-summary-save-in-mail (Unix mail format)
546 * gnus-summary-save-in-folder (MH folder)
547 * gnus-summary-save-in-file (article format)
548 * gnus-summary-save-body-in-file (article body)
549 * gnus-summary-save-in-vm (use VM's folder format)
550 * gnus-summary-write-to-file (article format -- overwrite)
551 * gnus-summary-write-body-to-file (article body -- overwrite)
552 * gnus-summary-save-in-pipe (article format)
554 The symbol of each function may have the following properties:
556 * :decode
557 The value non-nil means save decoded articles. This is meaningful
558 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
559 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
560 `gnus-summary-save-in-pipe'.
562 * :function
563 The value specifies an alternative function which appends, not
564 overwrites, articles to a file. This implies that when saving many
565 articles at a time, `gnus-prompt-before-saving' is bound to t and all
566 articles are saved in a single file. This is meaningful only with
567 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
569 * :headers
570 The value specifies the symbol of a variable of which the value
571 specifies headers to be saved. If it is omitted,
572 `gnus-save-all-headers' and `gnus-saved-headers' control what
573 headers should be saved."
591 "Coding system used to save decoded articles to a file.
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
602 and the functions to which you may set `gnus-default-article-saver':
604 * gnus-summary-save-in-file
605 * gnus-summary-save-body-in-file
606 * gnus-summary-write-to-file
607 * gnus-summary-write-body-to-file
609 Those commands and functions save just text displayed in the article
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.
612 Otherwise, raw articles will be saved."

663 value is a list of possible files to save in if the match is
664 non-nil.
666 If the match is a string, it is used as a regexp match on the
667 article. If the match is a symbol, that symbol will be funcalled
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.
