<h2 id="introduction">Introduction</h2>
<p>Welcome to “All Things <code>WEB</code>” in TeX Live.</p>
<p>Here you find the documented source code of all major
<code>WEB</code> and <code>CWEB</code> programs in readable format. The
<code>NAMED</code> entries represent the unmodified base sources as
written by their respective authors, the attached <code>chg</code> links
point to only the changed sections (or modules) as applied for release
in the TeX Live distribution, so you may want to study these pairs in
parallel. Care has been taken to keep the section numbering intact.</p>
<p>Although not all the programs presented here are written or
maintained by Donald Knuth, it is more convenient for everything to be
collected in one place for reading and searching. And they all stem from
the system that Knuth created.</p>
<p>Note that all <code>WEB</code> programs are mogrified from Pascal
code to C code before compilation, so further modifications and
amendments will occur for the real thing, i.e., the production of the
executable <code>WEB</code> programs. (The <code>CWEB</code> programs do
not require these extra modifications, they get linked directly to the
external runtime environment.)</p>
<p>If you believe to have found anything that remains technically,
historically, typographically, or politically incorrect in any of these
files, please feel free to <a href="https://tug.org/texmfbug/">report
bugs in TeX and friends</a> or <a
href="mailto:andreas_github@freenet.de">contact the maintainer of this
collection</a> directly.</p>
