534 * gnus-summary-save-in-mail (Unix mail format)
535 * gnus-summary-save-in-folder (MH folder)

539 * gnus-summary-write-to-file (article format -- overwrite)
540 * gnus-summary-write-body-to-file (article body -- overwrite)
542 The symbol of each function may have the following properties:
544 * :decode
545 The value non-nil means save decoded articles. This is meaningful
546 only with `gnus-summary-save-in-file', `gnus-summary-save-body-in-file',
547 `gnus-summary-write-to-file', and `gnus-summary-write-body-to-file'.
549 * :function
550 The value specifies an alternative function which appends, not
551 overwrites, articles to a file. This implies that when saving many
552 articles at a time, `gnus-prompt-before-saving' is bound to t and all
553 articles are saved in a single file. This is meaningful only with
554 `gnus-summary-write-to-file' and `gnus-summary-write-body-to-file'.
556 * :headers
557 The value specifies the symbol of a variable of which the value
558 specifies headers to be saved. If it is omitted,
559 `gnus-save-all-headers' and `gnus-saved-headers' control what
560 headers should be saved."

581 commands including:
583 * gnus-summary-save-article-file
584 * gnus-summary-save-article-body-file
585 * gnus-summary-write-article-file
586 * gnus-summary-write-article-body-file

591 * gnus-summary-save-body-in-file
592 * gnus-summary-write-to-file
593 * gnus-summary-write-body-to-file

596 buffer to a file if the value of this variable is non-nil. Note that
597 buttonized MIME parts will be lost in a saved file in that case.
598 Otherwise, raw articles will be saved."

652 article. If the match is a symbol, that symbol will be funcalled
653 from the buffer of the article to be saved with the newsgroup as the
654 parameter. If it is a list, it will be evalled in the same buffer.
