[jsword-devel] BibleDesktop in SWT

[DM Smith]

Another difference is the license. SWT uses EPL (Eclipse Public License, 
see http://www.eclipse.org/legal/epl-v10.html for details).
I think this raises the question of how compatible is it with the GPL. 
The EPL seems to allow us to distribute a program under the GPL,
but does not allow for GPL to be viral. Since GPL is viral, it does not 
look like we can freely mix the two of them.

The Apache License has a similar bent (which is what Lucene is licensed 
under), but we use it purely as an API to a separate set of services.
So our code is not a derived work of Lucene.

The SWT does not provide such a clean separation in our code. We will be 
blending SWT and our code in a significant manner. So our
work will clearly be a derived work of SWT and GPL.

Any input? Can we go with SWT and if so how? (Let's go for Light and not 
for Heat :)
