The Babeltrace project provides trace read and write libraries, as well
as a trace converter. Plugins can be created for any trace format to
allow its conversion to/from another trace format.

The main format expected to be converted to/from is the Common Trace
Format (CTF). The default input format of the "babeltrace" command is
CTF, and its default output format is a human-readable text log. The
"babeltrace-log" command converts from a text log to a CTF trace.
