which use case does this address? What is the connection to an RTEMS 
application?

Why do I need sudo to run the commands?

Using my openSUSE 42.3 babeltrace yields:

     babeltrace run --component=A:source.text.dmesg 
--params='no-extract-timestamp=no' --key=path --value ./rtemtrace 
--component=B:sink.ctf.fs --key=path --value ./ --connect=A:B
     Error parsing options.

     BabelTrace Trace Viewer and Converter 1.2.4"

When I compile the babeltrace clone from you, then I get:

../install/bin/babeltrace run --component=A:source.text.dmesg 
--params='no-extract-timestamp=no' --key=path --value ./rtemtrace 
--component=B:sink.ctf.fs --key=path --value ./ --connect=A:B
ctf.fs sink creating trace in .//rtemtrace-1

Why do I need your babeltrace? Not being able to use a tool from a 
standard distribution makes it harder to do RTEMS tracing.

 From your Readme.md:

"These commands will show the generated metadata stream and a ctf trace 
stream."

What can I do with a metadata stream and the CTF trace stream?

At the moment I have absolutely no idea how I can use this stuff to do 
RTEMS tracing. I thought that I can trace an RTEMS application (e.g. 
task switches) and then see some graphical output in a tool like Trace 
Compass (http://tracecompass.org/#screenshots).

Quite frankly, I don't think that you worked 30+ hours per week on 
average for this GSoC project. If you want to pass the next evaluation, 
then you really have to work harder.
