The record data format is described in 
cpukit/include/rtems/recorddata.h. If you think this documentation is 
insufficient, unclear and needs to be improved, then please do this as 
part of the project.

With the Qemu simulation you set up during the project proposal, you are 
able to get a TCP stream of record items from the Qemu target to your 
host. You also have an example client which sorts this stream, 
determines the timestamps and prints the items.

Your job is now to convert the record item stream into a CTF stream.
