 * Instructions for building/compiling the sdrtrunk application.

 * Prerequisites:
 * Install and configure an OpenJDK version 27+ that includes the JavaFX modules (e.g. Bellsoft Liberica JDK)
 * - Optional: install and configure Gradle 9.8+
 *
 * Scenario 1: run the application via gradle command line from the source code root directory:

 *
 * Scenario 2: create an application release for the current operating system
 * command: ./gradlew runtimeZipCurrent
 * Note: release image is located in the /build/image/ directory
 *
 * Scenario 3: create releases for Linux and OSX operating systems using downloaded JDKs
 * command: ./gradlew runtimeZipOthers
 * Note: release images are located in the /build/image/ directory
 *
 * Scenario 4: create release for Windows operating system using downloaded JDK
 * command: ./gradlew runtimeZipWindows
