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. A back end to support full
hypertext or indexing takes about 250 lines; a simpler one can be
written in 40 lines of awk.  The primary sacrifice relative to WEB
is that code is seldom prettyprinted.
