Net::Z3950::DBIServer::LICENCE - the zSQLgate licence
THIS IS NOT FREE OR OPEN SOURCE SOFTWARE. You can download, unpack, build and evaluate it for free, but you may not deploy it without first purchasing a deployment licence.
The zSQLgate program and the Net::Z3950::DBIServer module (together known as ``the software'') are copyright (C) 2002-2005 Mike Taylor.
I am not a lawyer, so I am not going to try to write this licence in legalese. It's supposed to be a clear, English statement of what you are and are not allowed to do with the software. Because these terms are written in plain English, they are no doubt shot through with loopholes, which I respectfully ask you not to exploit. I think my intention is clear, and you should honour that. If you think my intention is not clear, then email me for clarification.
1. You are allowed to download this software for evaluation purposes. You can unpack it, build it, run it, see how it works and how it fits your needs, all at zero cost. This clause is called your EVALUATION LICENCE.
2. You may NOT deploy the software. For the purposes of this licence, deployment means running it for any purpose other than evaluation, whether or not you or anyone else makes a profit from doing so. If you wish to deploy the software, you must first contact me and arrange to purchase a DEPLOYMENT LICENCE. If you are unsure whether or not your proposed use of the software constitutes deployment, email me for clarification.
3. Once you have obtained a deployment licence, you may deploy the software in any manner you see fit for the duration of the licence, including charging end-users for the services you use it to provide. Multiple deployments require multiple licences.
4. The software remains my property even when a deployment licence has been obtained. A deployment licence does not constitute transfer of ownership.
5. You may modify your copy of the software (fix bugs, add features) if you need to, whether you are using it under the zero-cost evaluation licence or the pay-for deployment licence. I encourage you to send your changes back to me for integration into the master copy, but you are not obliged to do so. You may NOT pass your changes on to any other party.
6. There is NO WARRANTY for this software, to the extent permitted by applicable law. I provide the software ``as is'' without warranty of any kind, either expressed or implied, including, but not limited to, the implied warranties of MERCHANTABILITY and FITNESS FOR A PARTICULAR PURPOSE. The entire risk as to the quality and performance of the software is with you. Should the software prove defective, you assume the cost of all necessary servicing, repair or correction. In no event unless required by applicable law will I be liable to you for damages, arising out of the use of the software, including but not limited to loss of data or data being rendered inaccurate.
7. All rights to the software are reserved by the author except where this licence explicitly says otherwise.
