# ProxMenux - Complete Uninstall Optimizations Script

# ==========================================================
# Description:
# This script provides a complete uninstallation and rollback system
# for all post-installation optimizations applied by ProxMenux.
#
# It allows administrators to safely revert any changes made during the
# optimization process, restoring the system to its original state.
#
# This ensures full control over system configurations and gives users
# the confidence to apply, test, and undo ProxMenux enhancements as needed.
