Maybe it's hard to discover... Can I have some time?

* A simple command line application which reads the data from FreeTrack
* using the FreeTrackClient.dll interface.
*
* Assumes that a copy of the FreeTrackClient.dll is in the same folder,
* thought this does not necessarily have to be the same folder as the
* FreeTrack application itself.

Now, drop dead, please... When I said it's EASY to devs to put Freetrack suport, it's open, have SDK, I didn't think that Oleg will not have time to create a dynamic campain...

Get a life now, please! And I still waisting my time in all this nonsense...
