In a PR elsewhere, someone said this was a better way to provide a summary. Sure.

-* C# API for the lab streaming layer.
-* 
-* The lab streaming layer provides a set of functions to make instrument data accessible 
-* in real time within a lab network. From there, streams can be picked up by recording programs, 
-* viewing programs or custom experiment applications that access data streams in real time.
-*
-* The API covers two areas:
-* - The "push API" allows to create stream outlets and to push data (regular or irregular measurement 
-*   time series, event data, coded audio/video frames, etc.) into them.
-* - The "pull API" allows to create stream inlets and read time-synched experiment data from them 
-*   (for recording, viewing or experiment control).
