Which plugins to load can be configured by setting these environment variables:
21
- BRZ_PLUGIN_PATH: Paths to look for plugins in.
22
- BRZ_DISABLE_PLUGINS: Plugin names to block from being loaded.
23
- BRZ_PLUGINS_AT: Name and paths for plugins to load from specific locations.

The interfaces this module exports include:
27
- disable_plugins: Load no plugins and stop future automatic loading.
28
- load_plugins: Load all plugins that can be found in configuration.
29
- describe_plugins: Generate text for each loaded (or failed) plugin.
