* 4. If you purchased a license in the "ONE-TIME PURCHASE" model, the
* license is granted only for the PRODUCT version specified in the

* 5. If you purchased a license in the "SUBSCRIPTION" model, you may
* install and use any version of the PRODUCT during the subscription

* distribute your product and/or software with the incorporated
* PRODUCT royalty-free.
* 12. You may make copies of the PRODUCT for backup and archival purposes.
* 13. Any form of redistribution requires confirmation and signature of
* the COMMERCIAL USE by successfully calling the method:
* License.iConfirmCommercialUse(...)
* The method call is used only internally for logging purposes, and
* there is no connection with other external services, and no data is
* sent or collected. The lack of a method call (or its successful call)
* does not affect the operation of the PRODUCT in any way. Please see
* the API documentation.
* 14. The AUTHOR & PUBLISHER reserve all rights not expressly granted to

*
* ADDITIONAL CLARIFICATION ON WORKSTATION
*
* A workstation is a device, a remote device, or a virtual device, used by
* you, your employees, or other entities to whom you have commissioned
* tasks. For example, the number of workstations may refer to the number
* of software developers, engineers, architects, scientists, and other
* professionals who use the PRODUCT on your behalf. The number of
* workstations is not the number of copies of your end-product that you
* distribute to your end-users.
*
* By purchasing the COMMERCIAL LICENSE, you only pay for the number of
* workstations, while the number of copies/users of your final product
* (delivered to your end-users) is not limited.
*
* Below are some examples to help you select the right license size:
*
* Example 1: Single Workstation License
* Only one developer works on the development of your application. You do
* not use separate environments for testing, meaning you design, create,
* test, and compile your final application on one environment. In this
* case, you need a license for a single workstation.
*
* Example 2: Up to 5 Workstations License
* Two developers are working on the development of your application.
* Additionally, one tester conducts tests in a separate environment.
* You use three workstations in total, so you need a license for up to
* five workstations.
*
* Example 3: Up to 20 Workstations License
* Ten developers are working on the development of your application.
* Additionally, five testers conduct tests in separate environments.
* You use fifteen workstations in total, so you need a license for
* up to twenty workstations.
*
* Example 4: Site License
* Several dozen developers and testers work on the development of your
* application using multiple environments. You have a large,
* multi-disciplinary team involved in creating your solution. As your team
* is growing and you want to avoid licensing limitations, the best choice
* would be a site license.
*
* UPGRADE POLICY
*
* The PRODUCT is versioned according to the following convention:
*
* [MAJOR].[MINOR].[PATCH]
*
* 1. COMMERCIAL LICENSE holders can install and use the updated version
* for bug fixes free of charge, i.e. if you have purchased a license
* for the [MAJOR].[MINOR] version (e.g., 5.0), you can freely install
* all releases specified in the [PATCH] version (e.g., 5.0.2).
* The license terms remain unchanged after the update.
* 2. COMMERCIAL LICENSE holders for the [MAJOR].[MINOR] version (e.g., 5.0)
* can install and use the updated version [MAJOR].[MINOR + 1] free of
* charge, i.e., plus one release in the [MINOR] range (e.g., 5.1). The
* license terms remain unchanged after the update.
* 3. COMMERCIAL LICENSE holders who wish to upgrade their version, but are
* not eligible for the free upgrade, can claim a discount when
* purchasing the upgrade. For this purpose, please contact us via e-mail.
