+ * Execute script is a method used for running Kotlin Scripting mods.
+ *
+ * @param input the path to the input file containing the script to be executed
+ * @throws Exception if the input file is not found
+ *
+ * Example usage:
+ * ```kotlin
+ * @file:DependsOn("cc.unitmesh:prompt-script:0.3.8")
+ *
+ * import cc.unitmesh.prompt.executeScript
+ *
+ * executeScript("config/prompt.unit-mesh.yml")
+ * ```
+ *
+ * This method takes a string input representing the path to the input file containing the script to be executed.
+ * It checks if the file exists, and if not, throws an exception indicating that the input file was not found.
+ * If the file exists, it creates a ScriptExecutor object with the input file and executes the script using the execute() method of the ScriptExecutor class.
