xfpt binary package in Ubuntu Xenial s390x

 xfpt is a program that reads a file of plain text that contains relatively
 simple markup, and outputs an XML file. It is intended to simplify the
 management of XML data. It is not a program that attempts to turn a plain text
 document into XML. Markup within text is introduced by ampersand characters,
 but is otherwise "soft". You can define what follows the ampersand, for
 example, &" to generate a "quote" element. There is also a macro facility that
 allows for higher level concepts such as chapters, displays, tables, etc.
