#### 6.6.3 Document Groups

`nndoc` is a cute little thing that will let you read a single file as a newsgroup. Several files types are supported:

`babyl`

  The Babyl format.

`mbox`

  The standard Unix mbox file.

`mmdf`

  The MMDF mail box format.

`news`

  Several news articles appended into a file.

`rnews`

  The rnews batch transport format.

`nsmail`

  Netscape mail boxes.

`mime-parts`

  MIME multipart messages.

`standard-digest`

  The standard (RFC 1153) digest format.

`mime-digest`

  A MIME digest of messages.

`lanl-gov-announce`

  Announcement messages from LANL Gov Announce.

`git`

  `git` commit messages.

`rfc822-forward`

  A message forwarded according to RFC822.

`outlook`

  The Outlook mail box.

`oe-dbx`

  The Outlook Express dbx mail box.

`exim-bounce`

  A bounce message from the Exim MTA.

`forward`

  A message forwarded according to informal rules.

`rfc934`

  An RFC934-forwarded message.

`mailman`

  A mailman digest.

`clari-briefs`

  A digest of Clarinet brief news items.

`slack-digest`

  Non-standard digest format—matches most things, but does it badly.

`mail-in-mail`

  The last resort.

You can also use the special “file type” `guess`, which means that `nndoc` will try to guess what file type it is looking at. `digest` means that `nndoc` should guess what digest type the file is.

`nndoc` will not try to change the file or insert any extra headers into it—it will simply, like, let you use the file as the basis for a group. And that’s it.

If you have some old archived articles that you want to insert into your new & spiffy Gnus mail back end, `nndoc` can probably help you with that. Say you have an old `RMAIL` file with mail that you now want to split into your new `nnml` groups. You look at that file using `nndoc` (using the `G f` command in the group buffer (see Foreign Groups)), set the process mark on all the articles in the buffer (`M P b`, for instance), and then re-spool (`B r`) using `nnml`. If all goes well, all the mail in the `RMAIL` file is now also stored in lots of `nnml` directories, and you can delete that pesky `RMAIL` file. If you have the guts!

Virtual server variables:

`nndoc-article-type`

  This should be one of `mbox`, `babyl`, `digest`, `news`, `rnews`, `mmdf`, `forward`, `rfc934`, `rfc822-forward`, `mime-parts`, `standard-digest`, `slack-digest`, `clari-briefs`, `nsmail`, `outlook`, `oe-dbx`, `mailman`, and `mail-in-mail` or `guess`.

`nndoc-post-type`

  This variable says whether Gnus is to consider the group a news group or a mail group. There are two valid values: `mail` (the default) and `news`.
