541 "A function to save articles in your favorite format.
542 The function will be called by way of the `gnus-summary-save-article'
543 command, and friends such as `gnus-summary-save-article-rmail'.
545 Gnus provides the following functions:
547 * gnus-summary-save-in-rmail (Rmail format)
548 * gnus-summary-save-in-mail (Unix mail format)
549 * gnus-summary-save-in-folder (MH folder)
550 * gnus-summary-save-in-file (article format)
551 * gnus-summary-save-body-in-file (article body)
552 * gnus-summary-save-in-vm (use VM's folder format)
553 * gnus-summary-write-to-file (article format -- overwrite)
554 * gnus-summary-write-body-to-file (article body -- overwrite)
555 * gnus-summary-save-in-pipe (article format)
557 The symbol of each function may have the following properties:
559 * :decode
560 The value non-nil means save decoded articles. This is meaningful
561 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
562 `gnus-summary-write-to-file', `gnus-summary-write-body-to-file', and
563 `gnus-summary-save-in-pipe'.
565 * :function
566 The value specifies an alternative function which appends, not
567 overwrites, articles to a file. This implies that when saving many
568 articles at a time, `gnus-prompt-before-saving' is bound to t and all
569 articles are saved in a single file. This is meaningful only with
570 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
572 * :headers
573 The value specifies the symbol of a variable of which the value
574 specifies headers to be saved. If it is omitted,
575 `gnus-save-all-headers' and `gnus-saved-headers' control what
576 headers should be saved."
594 "Coding system used to save decoded articles to a file.
596 The recommended coding systems are `utf-8', `iso-2022-7bit' and so on,
597 which can safely encode any characters in text. This is used by the
598 commands including:
600 * gnus-summary-save-article-file
601 * gnus-summary-save-article-body-file
602 * gnus-summary-write-article-file
603 * gnus-summary-write-article-body-file

607 * gnus-summary-save-in-file
608 * gnus-summary-save-body-in-file
609 * gnus-summary-write-to-file
610 * gnus-summary-write-body-to-file
612 Those commands and functions save just text displayed in the article
613 buffer to a file if the value of this variable is non-nil. Note that
614 buttonized MIME parts will be lost in a saved file in that case.
615 Otherwise, raw articles will be saved."

666 value is a list of possible files to save in if the match is
667 non-nil.
669 If the match is a string, it is used as a regexp match on the
670 article. If the match is a symbol, that symbol will be funcalled
671 from the buffer of the article to be saved with the newsgroup as the
672 parameter. If it is a list, it will be evalled in the same buffer.
