jekyll binary package in Ubuntu Jammy s390x

 Jekyll is a simple, blog aware, static site generator. It takes a
 template directory (representing the raw form of a website), runs it
 through Textile or Markdown and Liquid converters, and spits out a
 complete, static website suitable for serving with Apache or your
 favorite web server.
 .
 This is also the engine behind GitHub Pages (http://pages.github.com),
 which you can use to host your project's page or blog right here from
 GitHub.
 .
 There are lot of plugins available and only the most common ones are
 suggested by the package. Look for more using 'jekyll plugin'.
