Please add build instructions

[yurivict]

Both this project and linked projects (OpenSourcePhysics/osp, etc) don't have any build instructions.

I would like to create a FreeBSD port and build from source, but how to build it? I don't want to use pre-built jars.

@yurivict , sorry for non-immediate answer :(
Thank you for your interest to OSPTracker!
You can try to use https://github.com/nickkolok/osptracker-build (ant/eclipse/IntelliJ Idea) or the original version https://github.com/fschuett/osptracker-build (ant/eclipse).

Please don't hesitate to write here if you have any problems.

The most probable problem that you will encounter is related to loading ffmpeg libraries. This is because the mechanisms of loading libraries differ from Linux to FreeBSD... AFAIK :)
If you want to build Xuggle version, please check out to branch bundle-jars-xuggle of https://github.com/nickkolok/osptracker-build

We will be happy to receive your pull-requests which add FreeBSD building compatibility (if any changes are needed).
