noweb binary package in Ubuntu Bionic amd64

 noweb is designed to meet the needs of literate programmers while
 remaining as simple as possible. Its primary advantages are
 simplicity, extensibility, and language-independence.
 .
 The noweb manual is only 3 pages; an additional page explains how to
 customize its LaTeX output. noweb works ``out of the box'' with any
 programming language, and supports TeX, latex, and HTML back ends.
 .
 The primary sacrifice relative to WEB is that code is not
 prettyprinted.
