{\noindent Dear Ed:}

This is to confirm our delivery to you of: 1) The December 1981 preliminary
draft of ``The WEB System of Structured Documentation'' by Donald E.
Knuth, and 2) A 9-bit non-labeled magnetic tape written in ascii at 1600
bpi, lrcl 133, blksize 7980, recfm FBA, containing the following files :
TANGLE.PAS, TANGLE.WEB, WEAVE.WEB, WEBHDR.TEX, and BASIC.TEX.

The hard-copy 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''.

The TANGLE.PAS file is in upper case, broken into lines not exceeding 72
characters per line at PASCAL-acceptable places.  The only concession to
readability is that the breaks are made after semicolons when this is
possible.

WEBHDR.TEX is the WEB header file that contains specific formatting
information needed by TEX to process the output from WEAVE. 

Thank you for your \$25 check which will be used to help defray the
expenses of making the tape, and for you willingness to help coordinate
the use of WEB on PRIME computers.  We would appreciate having the tape
returned to us as soon as you have transcribed it, and, above all, we
would like your comments and suggestions.
