[lttng-dev] Need help in converting trace data into CTF

Hi,

Babeltrace understand text based metadata file as long as it conforms to the TSDL
grammar.

See:
    https://diamon.org/ctf/#spec7
    https://diamon.org/ctf/#spec7.4
    https://diamon.org/ctf/#specC

For an example of metadata generator, you can look at Barectf[1] or
lttng-tools[2]
