3.2.13  User-Agent

   The User-Agent header contains information about the user agent
   (typically a newsreader) generating the article, for statistical
   purposes and tracing of standards violations to specific software
   needing correction.  It is intended that this header be suitable for
   use in Email.

   user-agent      =  "User-Agent:" SP 1*product [CFWS] CRLF

   product         =  [CFWS] token [ [CFWS] "/" product-version ]

   product-version =  [CFWS] token

   This header MAY contain multiple product-tokens identifying the agent
   and any subproducts which form a significant part of the posting
   agent, listed in order of their significance for identifying the
   application.

      NOTE: This header supersedes the role performed redundantly by
      experimental headers such as X-Newsreader, X-Mailer, X-Posting-
      Agent, X-Http-User-Agent, and other headers previously used on
      Usenet and in Email for this purpose.  Use of these experimental
      headers SHOULD be discontinued in favor of the single, standard
      User-Agent header.

      NOTE: [RFC2616] describes a similar facility for the HTTP
      protocol.  This specification differs in that "{" and "}" are
      allowed in tokens (<product> and <product-version>) and comments
      are permitted wherever whitespace is allowed.
