Dear list,

I am learning ryu and I am now very confused about the concept of _CONTEXT
and event here.

For event, I don't know if I am right about this, please point out if I
understand it wrong:

Event(request if sync is required) is used to pass information across
different applications, like if I start switches.py and my own app together
and I can send request to switches.py through get_switch() to get switch
info.

Then what does _CONTEXT do? For example in the link exaggeration example,
the simple switch is in the context of lacplib. Then what is the relation
between "lib" and "app" in RYU? What does the fact that
simple_switch_lacp_13.py is in the CONTEXT of lacplib mean?

Thank you so much
-Mo
