-@cindex Semi-gnus
-
-In addition to the versions of Gnus which have had their releases
-coordinated by Lars, one major development has been Semi-gnus from
-Japan.  It's based on a library called @acronym{SEMI}, which provides
-@acronym{MIME} capabilities.
-
-These Gnusae are based mainly on Gnus 5.6 and Pterodactyl Gnus.
-Collectively, they are called ``Semi-gnus'', and different strains are
-called T-gnus, ET-gnus, Nana-gnus and Chaos.  These provide powerful
-@acronym{MIME} and multilingualization things, especially important for
-Japanese users.
