Yes, its just that this was easy enough to improve the current
situation, this is still a shell script that I wrote as a way to show
how to do some porcelain out of 'perf buildid-list'.

But it probably will be better to have it as a full fledged tool, as I
can imagine people asking for .tar.xz support, and I also want to be
able to tell it to strip debugging information, putting there just the
symtabs, etc.

So if you can get this one in, the current situation would be improved
and I'll eventually get to implement your suggestion.
