frenetic-lang/frenetic — pull request #252 by seliopou (2014-02-14 05:34:15+00:00)
Title: Add controller actions (with pipes)

This pull request allows users to write frenetic applications that will send packets to the controller, using the following syntax:

```
port :=
```

Rather than setting the port to a number, users can set the port to an identifier, indicating that the packet should be sent to the controller and when processed, be associated with that identifier.

Closes #246.
