Photon uses several other libraries, which fall under a variety of licenses:
*OpenAL support is optional, if OpenAL is not found, photon can be compiled without it. This is done so that those wishing to keep their application free of LGPL libraries may do so while still using photon.
Understanding and complying with Open Source licenses can be a daunting task, but in this case is rather simple. If you are distributing an application which uses photon and it's dependencies you must do the following:
If you comply with all three licenses (don't take credit for what you didn't do, credit Freetype and OpenAL, and provide the LGPL and a link to OpenAL's source you can do what you wish with your application, including make it closed source and/or sell it)
For convenience I have written a licensing template that should satisfy most users of photon. It is essentially what I would use in distributing any binaries made with photon and it's dependencies. (Note: I credit the zlib libraries which isn't necessary but I feel it's proper.)
