Creating Application Instance

Controller performs the following actions when it is instantiating an application package:

Prepares all the data and conditions necessary for instantiating:
- Presents an application-usage license text (if any is provided in the package) to a user and provides tools necessary for accepting the license if it is required. For details, refer to the 5.2.2 License Agreement section in the Specification.
- Determines and satisfies the application requirements. For details, refer to the 5.2.6. Requirements, 5.3.2.2.3. Aspect-defined Environment Variables sections in the Specification.
- Prompts the user to configure the application installation settings and processes the submitted settings. For details, refer to the 5.3.2.2. Environment Variables, 5.2.4. Entry points, 5.2.5. Service Settings sections in the Specification.
- Retrieves the application's global configuration and prepares to apply it to the instance. For details, refer to 5.2.5. Service Settings, 5.3.2.2.2. Settings sections in the Specification.
  Note: The order of these preparatory sub-stages depends on the Controller implementation.
Deploys the application files to a site. For details, refer to the 5.3.1. URL mapping, 5.3.2.2.3. Aspect-defined Environment Variables sections in the Specification.
Runs the application configuration script passing to it all the available information about the application in the form of environment variables created on the previous stages. For details, refer to the 6.6. Configuration Script Language, 5.3.2. Configuration script, 6.4. Environment Variables sections in the Specification.
