Friendly warning of licence

[CodeMonkey]

Hi everyone, after looking at your main page I found out that you use the Crystal Space 3D engine. The engine is under the LGPL licence. This means that if your product is derived from the engine, your product must also follow the same licence. I suggest you all read http://www.gnu.org/licenses/lgpl.html

your licence states:

\'You may not copy, modify, publish, transmit, sell, participate in the transfer or sale or reproduce, create derivative works from, distribute, perform, display or in any way exploit any of the Material released under this License unless expressly permitted by the PlaneShift Team\'

This means that in effect, your licence on your home page is in violation of the LGPL licence.

Just a friendly reminder.

Pleaser inform yourself first!
Read up on the inet what the difference between LGPL and GPL is! (why do you think exist 2 licenses The changed/derived work is the Crystal Space engine itself, so each change we do to the engine must be opened! But we don\'t need to open our source if we just use the engine. (It\'s something different for GPL source).

So before you\'re shocked about our closed nature . Only the  content will be proprietary (but still free to download), our source code is and will be GPL!
Perhaps we\'ll even open content later, but that\'s not sure

As long as the source code itself is viewable and also that the source code can be used freely for other projects it will be ok. The GPL still applies becasue your game is derived from a LGPL engine.

[MatzeB]

Please go to http://www.gnu.org and read exactly.

The crystal space engine is licensed under the LGPL, but the \'Material\' referred too is only specific to whatever covered under our license, which is currently graphics, maps, sprites, rules, ideas and audio. This is done just to protect the originality of the project, and it will be clearly explained in the releases the content released under that license. The source will always be released but only if you use it to produce a game of your own, without infringing on the ideas or content of the game. As MatzeB says, we can choose what parts of the project are licensed on the GPL and there are no requirements at all to open the sources because of our use of Crystal Space (since it is LGPL).

I believe this can all be summarized by saying that you are free to take the PS source code (the actual C++ code) and make your own game, but you are NOT free to use any of the artwork, models or music because they are not covered by the GPL or LGPL, but in fact are covered by the Planeshift License, which is posted on the main website somewhere I\'m sure.

Keep in mind that Crystal Space is LGPL. This does NOT mean that a project using CS has to be LGPL. i.e. you can even make closed source games using CS. The LGPL (as opposed to the GPL) specifically allows that. The only restriction is that modifications to CS have to be LGPL.
