I think this is missing a period and a space between "package" and
"Equivalent", but see below.

This only checks for libbabeltrace if --with-babeltrace is specified.
So, the text above about equivalency isn't really correct, at least the
way I read it; if you want to give --with-babeltrace-include, you have
to also give --with-babeltrace.

I'm not sure how to reword the above to make it more clear.
Perhaps spelling out the options.

Lots of functions missing intro comments.
Most of the comments can be really short, since these are just
implementations of target methods.

I think just delete this.

Unfortunately for you there is plenty of this patch I don't feel
competent to review.  I don't know much about the target API.

If nobody else looks after a decent interval, ping me and I will ok it.
I suppose if these methods parallel the existing tfile target, then that
is pretty good evidence for it being ok.

The rest seems ok to me.
