# GERTIE Install Script
# Generates systemd service files from templates using values in gertie.toml
#
# Usage:
#   1. cp gertie.toml.example gertie.toml
#   2. Edit gertie.toml with your username and install path
#   3. ./install.sh
#
# What this does:
#   - Reads GERTIE_USER and GERTIE_DIR from gertie.toml
#   - Generates .service files in generated-services/
#   - Optionally installs them to /etc/systemd/system/ (requires sudo)
