+Welcome to mmh, meillo's MH version
+===================================
+This program does only one small, but important task: it sets up mmh for your
+user account. Afterwards you can access the functions of mmh by using any of
+the specialized tools from the mmh toolchest. The man page mmh(1) lists them.
+Consult the man pages of the individual programs for further documentation.
+
+But now, let's set up mmh for you ...
