# Basic genfile workflow example
#
# This script demonstrates the fundamental genfile workflow:
# 1. Starting REPL mode
# 2. Creating a new archive
# 3. Adding template files
# 4. Defining parameters
# 5. Saving the archive
#
# The commands are sent to genfile's REPL mode, which maintains
# archive state across commands within a single session.

set -e  # Exit on any error
