# Dynamic inventory script which lets you use nodes discovered by Canonical's
# Landscape (http://www.ubuntu.com/management/landscape-features).

# Requires the `landscape_api` Python module
# See:

#
# Environment variables

# - `LANDSCAPE_API_KEY`
# - `LANDSCAPE_API_SECRET`
# - `LANDSCAPE_API_SSL_CA_FILE` (optional)
