# OpenIM CronTask Control Script
#
# Description:
# This script provides a control interface for the OpenIM CronTask service within a Linux environment. It supports two installation methods: installation via function calls to systemctl, and direct installation through background processes.
#
# Features:
# 1. Robust error handling leveraging Bash built-ins such as 'errexit', 'nounset', and 'pipefail'.
# 2. Capability to source common utility functions and configurations, ensuring environmental consistency.
# 3. Comprehensive logging tools, offering clear operational insights.
# 4. Support for creating, managing, and interacting with Linux systemd services.
# 5. Mechanisms to verify the successful running of the service.
#
# Usage:
# 1. Direct Script Execution:
# This will start the OpenIM CronTask directly through a background process.
# Example: ./openim-crontask.sh openim::crontask::start
#
# 2. Controlling through Functions for systemctl operations:
# Specific operations like installation, uninstallation, and status check can be executed by passing the respective function name as an argument to the script.
# Example: ./openim-crontask.sh openim::crontask::install
#
# Note: Ensure that the appropriate permissions and environmental variables are set prior to script execution.
