August, 1996 Dear Arthur: A CD-ROM of useful software, tools, and facts for system administrators has replaced the appendices as part of the second edition of UNIX System Administration Handbook (Prentice Hall, 1995). We are about to do a new printing of the book and CD and would like to include your software package "tzcode, tzdata" on the CD. Please excuse the form-letter-ness of this message, it's due to the number of software packages in question and a lack of sophistication in my PERL programming skills. My purpose in writing covers three issues: availability, correctness of our index entry, and continuing permission to include your software. 1) We would like to confirm that "tzcode, tzdata" is in fact freely redistributable and that you have no objection to its inclusion on our CD. The CD is included with the book at no cost; the current version is available as an update for a modest distribution cost. The image of the CD can also be accessed by anonymous ftp from cs.colorado.edu. 2) We want to make sure that our page-length "index entry" from the CD for your software is accurate and complete. Both the index entry and the tentative table of contents of the CD are included below. 3) In order to expedite future updates of the CD we'd like you to choose a permission model from those listed below (or suggest your own): a) OK to include the software forever; don't bother me again b) OK to include the software, but ask each time you revise the CD c) Please DO NOT distribute my software We intend to upgrade as software evolves, but new releases of the CD will track printings of the book and so the timing is not under our control. If you agree to a "don't ask me again" model, it would help us keep our index pages current and correct if you would make the README associated with your software include any changes in the maintainer or primary ftp site. Please use email to respond; if we don't hear from you we will assume that it is OK to include your software and that our index entry is correct (permission model b), but we would prefer an explicit answer. Thank you, -evi Evi Nemeth, Assoc Prof Computer Science Dept University of Colorado Boulder, CO 80309-0430 303-492-5385
