methods to @code{Net::SMTP}, @code{Net::POP3} etc.

Mail has been designed with a very simple object oriented system that
really opens up the email messages you are parsing, if you know what you
are doing, you can fiddle with every last bit of your email directly.")

It is acknowledged that many strings defined by heredocs are just code and
fact is that most parsers are insensitive to indentation.  If, however, the
strings are to be used otherwise, be it for printing or testing, the extra
indentation will probably be an issue and hence this gem.")
