Tasks support a notification like channel that they can use to emit information that has occurred internal to then be received by any attached listeners. This kind of notification even works when ran remotely; so this example shows how to use that system to do something useful.

Testing and requirements
Requirements
Because TaskFlow has many optional (pluggable) parts like persistence
backends and engines, we decided to split our requirements into two
parts: - things that are absolutely required by TaskFlow (you can't use
TaskFlow without them) are put into requirements-pyN.txt
(N being the Python major version number used to
install the package); - things that are required by some optional part
of TaskFlow (you can use TaskFlow without them) are put into
optional-requirements.txt; if you want to use the feature
in question, you should add that requirements to your project or
environment; - as usual, things that required only for running tests are
put into test-requirements.txt.
Tox.ini
Our tox.ini file describes several test environments
that allow to test TaskFlow with different python versions and sets of
requirements installed. Please refer to the tox documentation to
understand how to make these test environments work for you.
Developer documentation
We also have sphinx documentation in docs/source.
