{\noindent Dear Dan:}

Under separate cover, we are sending you: 1) The November 1981 preliminary
draft of ``The WEB System of Structured Documentation'' by Donald E.
Knuth, and 2) The older documentation on ``The PASCAL-coded version of TEX''
August 1981 revision, which, as I may have told you, is soon to be made obsolete
by the newer version written in the WEB language.

The hard-copy WEB report was written in WEB and prepared for printing through
the use of the WEAVE program and of TEX.  Appendices to this report
contain the complete WEAVE-produced listings of TANGLE and of WEAVE
itself. Appendix G, on page 176, outlines the procedure that may be
necessary to install the WEB system on your computer.

An attempt has been made to make TANGLE and WEAVE reasonably system
independent but some system dependencies still remain.  The modules that
may require attention are listed in the indices on page 103 and page 170
in the documentation under ``system dependencies''.

Unfortunately, and previously unbeknown to me, we are not able to accept
purchase orders, so I am returning your order to you.  Instead, we would
appreciate receiving a check made out to Stanford University.

Let me know when you are in a position to start implementing TEX on your
system and I will arrange for you to get the necessary tapes.  In the
meantime, I would appreciate any comments that you may care to make
regarding the documentation.
