# Deploy hookshot transformation functions to Matrix room state.
# Each .js file in this directory maps to a webhook by the same name (case-sensitive).

# Usage:
#   ./deploy.sh                  # deploy all hooks
#   ./deploy.sh proxmox.js       # deploy one hook
#
# Requirements:
#   MATRIX_TOKEN  - access token with power level >= 50 in the target room
#   MATRIX_SERVER - homeserver URL (default: https://matrix.lotusguild.org)
#   MATRIX_ROOM   - room ID where hooks are registered
