Subject: Re: [PATCH v5 7/8] perf scripts python: Add command execution for
perf gecko script

But this isn't working:
[root@...e ~]# perf script gecko
usage: gecko.py [-h] [--user-color USER_COLOR] [--kernel-color KERNEL_COLOR]
gecko.py: error: unrecognized arguments: -i -
[root@...e ~]#
See below how this pipes the 'record' script with its 'report'
counterpart.
[root@...e ~]# strace -s200 -e execve perf script gecko
execve("/root/bin/perf", ["perf", "script", "gecko"], 0x7ffd0b021c18 /* 23 vars */) = 0

and pipe it into /var/home/acme/libexec/perf-core/scripts/python/bin/futex-contention-report
I also renamed perf-gecko to just gecko, no need to have the 'perf-'
prefix.

I put what I have on this branch:

Later I'll try and work on have this working if you don't beat me to it
