Viewing the trace output is buggy right now. I will have to combine the
rest. I will push the required things in the repository by end of today and
notify you.

CTF allows traces to be natively generated by any C/C++ application or
system, as well as by bare-metal (hardware) components. CTF is a flexible
tracing format with a range of configurable datatypes. This allows CTF to
describe any binary structure. Also since CTF is a binary trace format it
is faster to write. The post processing (eg Trace Compass) and real time
monitoring tools available with it are valuable.
