Introduction

Welcome to “All Things WEB” in \TeX\ Live.

Here you find the documented source code of all major WEB and CWEB programs in readable format. The NAMED entries represent the unmodified base sources as written by their respective authors, the attached chg 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 together. Care has been taken to keep the section numbering intact.

Although not all 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.

Note that all WEB 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 WEB programs. (The CWEB programs do not require these extra modifications, they get linked directly to the external runtime environment.)

If you believe to have found anything that remains technically, historically, typographically, or politically incorrect in any of these files, please feel free to report bugs in \TeX\ and friends or contact the maintainer of this collection directly.
