Following a file, or cloning tail

[Darrell Gallion]

If your on Windows and can wait for the file to complete writing, check out

The best solution might be to use popen if you can.

Trail might be a problem if the other application doesn't flush() the file
once in a while.
If it does you should be able to just call read() on an interval or use
select to avoid polling.
Select won't help you on Windows though, but Win32 calls will.
