mmh binary package in Ubuntu Oracular armhf

 This is the mmh mail user agent (reader/sender), a command-line based mail
 reader that is powerful and extensible. mmh is an excellent choice for
 people who receive and process a lot of mail.
 .
 Unlike most mail user agents, mmh is not a single program, rather it is a
 set of programs that are run from the shell. This allows the user to
 utilize the full power of the Unix shell in coordination with mmh.
 .
 Mmh is a modified version of the electronic mail handling system nmh.
 Nmh (new MH) itself was originally based on the package MH-6.8.3, and
 was intended to be a (mostly) compatible drop-in replacement for MH.
 In contrast, mmh is not intended to be a drop-in replacement for nmh,
 rather mmh breaks compatibility to nmh in order to modernize and
 simplify it.
