+# Daq_lite
+
+Testing out a method to allow external processes to consume a CDS data stream.
+
+The idea is to have a single process which consumes the CDS data stream + metadata and exports a combiled meta-data data buffer set via shared memory.
+
+Library interfaces are provided to consume this, doing channel listing and data access.
+
+The goal is to provide a simple interface such that a process does not need to know about the CDS data layout, only
+the channels that are requested.  The application would only need to know the channels, and then wait for
+signals for data being delivered.
