mailtextbody binary package in Ubuntu Precise armhf

 Mailtextbody reads a complete email message on stdin and returns the body
 on standard out. -- Technically speaking it returns the decoded first
 text/plain MIME part of any however nested MIME message or just the body of
 a non-MIME message otherwise.
 .
 Mailtextbody can therefore easily be included in other tools using
 pipes.
