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.)
