The streams of uuids (and associated paths, and/or other attributes) used to communicate between various applications are specified to have the following form:

• Each entry of uuid and attributes is stored on a single line

• Each such line is formatted as a Tcl list holding the uuid and the attributes (most often just the path), in this order.

• Each received line may have leading and trailing whitespace. Such has to be ignored by all tools. All streams generated by the lspace tools will be without any leading / trailing whitespace.
