I think it should be FLAG instead of FLAGS

Not in gflags: https://gflags.github.io/gflags/#using

It turns out someone updated this tool to use base/flags instead of gflags while
you're working on it, so you'll find out when you rebase that Oliver was
actually right ;)

Oh, I see. I'll get to the rebase when everything else is done and dusted.

This looks like it could use an update :-)

[hlundin-webrtc, 2017/05/30 14:56:07]

You think? :)
Done!
