# should be named oslo.config.generator.rc and be placed in the same directory.

# You can then export the following variables:
# CEILOMETER_CONFIG_GENERATOR_EXTRA_MODULES: list of modules to interrogate for options.
# CEILOMETER_CONFIG_GENERATOR_EXTRA_LIBRARIES: list of libraries to discover.
# CEILOMETER_CONFIG_GENERATOR_EXCLUDED_FILES: list of files to remove from automatic listing.
