Re: [flux-dev] Status update

Hey Fjodor,

don’t worry, all fine… I ran your code successfully on my machine, works nicely.
And yes, the integration into the Eclipse plugin was a goal. But my assumption was that we could keep the ability to run the file watcher standalone, too… :-)

Not a requirement to successfully complete your GSoC work, though… ;-)

Cheers,
-Martin
