gnus: Uuencoding and Posting

 
 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’.
