wpp 2.13.1.35-4 (s390x binary) in ubuntu xenial

 WPP is a small Perl script that allows preprocessing of HTML files.
 You can define variables, which are abbreviations for longer
 constructs, and include common HTML fragments. It's useful for
 giving a uniform layout to different HTML pages. It can be used in
 cgi-bin programs for automatic generation of pages. With less HTML
 code inside them you can make more flexible and readable scripts.
 .
 WPP provides four separate facilities that you can use as you see
 fit: inclusion of text/HTML fragments, variable expansion,
 conditional generation, macro expansion.
