Zilch is NOT nor ever has been, public domain or free software.
The registered version of Zilch may not be duplicated other than for backup purposes. A registered copy of Zilch must be treated like a book. This means that the same registered copy of Zilch may not be used in more than one computer at the same time, just as a book may not be read by more than one person at the same time (without making an illegal copy).
Users are granted a limited license to use the Shareware version of Zilch for a limited evaluation period of up to 30 days, in order to determine if it suits their needs. Any other use of Zilch or use past the evaluation period requires registration.
All users are granted a limited license to copy the "Shareware" version of Zilch for the purpose of allowing others to try it subject to the above restrictions as well as these:
Zilch must be distributed in absolutely unmodified form, to include ALL program, documentation, and other files.
No charge or payment may be accepted for Zilch.
All shareware vendors/distribution firms must clearly explain and/or explicitly state to the purchaser of shareware diskettes that the purchase of shareware programs has NOT registered the software with the author.
WebMasters may post the unregistered "Shareware" version of Zilch on their websites for downloading by their users without written permission only if the above conditions are met, and only if no special fee is necessary to access the files (a general fee to access the Website is ok).
Distributors of "Public Domain", "Shareware" and/or "User Supported" software MUST obtain WRITTEN PERMISSION from Michael J. Riley and before distributing Zilch and must follow the above conditions. This condition statement supersedes all previous agreements.
Business, corporate, government and nonprofit agencies that intend to use Zilch on more than one computer must obtain a site license. The fee charged for a site license depends on the number of computers Zilch will be used on.
