# Utility script for iOS and Android Emulators
# ============================================
#
# Purpose:
# --------
# This script helps to start and kill iOS simulators and Android emulators instances.
#
# How this script helps:
# ----------------------
# This script streamlines the process of starting and killing on both android and ios
# platforms.

# Use functions and variables from the utils script
source scripts/shellUtils.sh
