xemacs21-mule-canna-wnn-dbgsym 21.4.22-14ubuntu1 (arm64 binary) in ubuntu xenial

 XEmacs is a full fledged programming language with a mail reader,
 news reader, info browser, web browser, calendar, specialized editor
 for more programming languages and other formats than most people
 encounter in a lifetime, and much more.
 .
 This package contains the actual binary used to run XEmacs. It
 depends on the xemacs21-support package for lisp and etc files, and
 the xemacs21-bin package for supporting binaries. This binary has
 support for the input extensions Canna and WNN compiled in.
 .
 Mule is an extension to (x)emacs that allows for the display and
 input of non-European characters. This binary allows for input and
 display whereas the xemacs21-mule package only does display.
 .
 This package actually contains one of the three xemacs binaries
 available. They are xemacs21-nomule, xemacs21-mule and
 xemacs21-mule-canna-wnn.
