This is a tracing library based on the Dapper work by Google.
The overall architecture is pretty simple. A trace is a tree of spans, each span representing some part of the overall computation.
In the future, we may provide a span writer for connecting with Twitter's Zipkin.
Documentation can be found at http://opendylan.org/documentation/tracing/
If you want to build the documentation yourself, you will need to add documentation/sphinx-extensions from your copy of Open Dylan to your PYTHONPATH.
