    (synopsis "Literate programming tool")
    (description
     "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—especially noticeable when compared
with other literate-programming tools.  noweb uses 5 control sequences to
WEB's 27.  The noweb manual is only 4 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, HTML, and troff back ends.")
