|

333 For instance, if you would like to save articles related to Gnus in
|
|
|
334 the file \"gnus-stuff\", and articles related to VM in \"vm-stuff\",
|
|
|
335 you could set this variable to something like:
|

|
336
|
|
|
337 '((\"^Subject:.*gnus\\|^Newsgroups:.*gnus\" \"gnus-stuff\")
|
|
|
338 (\"^Subject:.*vm\\|^Xref:.*vm\" \"vm-stuff\"))
|
|
|
339

340 This variable is an alist where the where the key is the match and the
|
|
|
341 value is a list of possible files to save in if the match is non-nil.
|
|
|
342
|
|
|
343 If the match is a string, it is used as a regexp match on the
|
|
|
344 article. If the match is a symbol, that symbol will be funcalled
|
|
|
345 from the buffer of the article to be saved with the newsgroup as the
|
|
|
346 parameter. If it is a list, it will be evaled in the same buffer.
|
|
|
347
|
|
|
348 If this form or function returns a string, this string will be used as
|
|
|
349 a possible file name; and if it returns a non-nil list, that list will

350 be used as possible file names."
