A  second  issue  comes  up  also,  moreover.   As  Internet
standards--usually  canonicalized in RFCs--have evolved, and
as  Python  libraries have become more versatile and robust,
some  newer modules have superceded older ones. In a similar
way, for example, the [re] module replaced the older [regex]
module.  In the interests of backwards compatibility, Python
has  not  dropped  any  Internet  modules  from its standard
distributions.   Nonetheless,  the [email] module represents
current  "best practice" for most tasks related to email and
newsgroup   message   handling.     The   modules  [mimify],
[mimetools],  [MimeWriter],  [multifile],  and  [rfc822] are
likely  to  be  utilized  in  existing  code,  but  for  new
applications,  it  is  better  to  use  the  capabilities in
[email] in their stead.
