Redirect all output (io:format) to file or remote shell

[Max Lapshin]

Hi. I've decided that using runit for starting erlyvideo is not usable
because of problems with restarting.

Now I'm interested if it is possible to save somehow io:format output
into file?
I haven't found how to tell standard_io to save all io requests to
file or to some server (it is even better).
