``tractor`` is an attempt to bring trionic_ `structured concurrency`_ to
distributed multi-core Python; it aims to be the Python multi-processing
framework *you always wanted*.
``tractor`` lets you spawn ``trio`` *"actors"*: processes which each run
a ``trio`` scheduled task tree (also known as an `async sandwich`_).
*Actors* communicate by exchanging asynchronous messages_ and avoid
sharing any state. This model allows for highly distributed software
architecture which works just as well on multiple cores as it does over
many hosts.
The first step to grok ``tractor`` is to get the basics of ``trio`` down.
A great place to start is the `trio docs`_ and this `blog post`_.

Feel like saying hi?
--------------------
This project is very much coupled to the ongoing development of
``trio`` (i.e. ``tractor`` gets most of its ideas from that brilliant
community). If you want to help, have suggestions or just want to
say hi, please feel free to reach us on in our `matrix channel`_. If
matrix seems too hip, we're also mostly all in the the `trio gitter
channel`_!
