xemacs21-nomule binary package in Ubuntu Focal s390x

 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 does
 not have any of the mule stuff compiled into it. It should be faster
 than the xemacs21-mule and xemacs21-mule-canna-wnn packages because
 it does not contain the fairly large bit of code for either the
 display or input of non-European characters.
 .
 This package actually contains one of the three xemacs binaries
 available. They are xemacs21-nomule, xemacs21-mule and
 xemacs21-mule-canna-wnn.
