##### 3.17.5.3 Uuencoding and Posting

`gnus-uu-post-include-before-composing`
  Non-`nil` means that `gnus-uu` will ask for a file to encode before you compose the article. If this variable is `t`, you can either include an encoded file with `C-c C-i` or have one included for you when you post the article.
`gnus-uu-post-length`
  Maximum length of an article. The encoded file will be split into how many articles it takes to post the entire file.
`gnus-uu-post-threaded`
  Non-`nil` means that `gnus-uu` will post the encoded file in a thread. This may not be smart, as no other decoder I have seen is able to follow threads when collecting uuencoded articles. (Well, I have seen one package that does that—`gnus-uu`, but somehow, I don't think that counts...) Default is `nil`.
`gnus-uu-post-separate-description`
  Non-`nil` means that the description will be posted in a separate article. The first article will typically be numbered (0/x). If this variable is `nil`, the description the user enters will be included at the beginning of the first article, which will be numbered (1/x). Default is `t`.
