# This is a demo is how to use the xpcom.server "tracer" facility.

# This demo installs a tracer that uses the Python profiler. It then
# creates the Python test component, and references some methods
# and properties. It then dumps the profile statistics.
# This same technique could also be used for debugging, for example.
