note that TRB source code modifications are not proprietary
In other words, you can build on this software in your proprietary software but can't change the Trailblazer source unless you're willing to contribute it back.
loophole: I wonder if this will actually just push people to move their code -- which at the core is/would be a direction modification to the source code - out to a separate module. That's so easy to do with Ruby, so this restriction hardly seems like it would have any effect on encouraging contributions.
The LGPL allows users to use and integrate LGPL software components into their own software without being required to release the source code of their own software components. However, if users modify LGPL software components (“derivative work”), they are required to make the modified software component available under the same LGPL license. To avoid the latter with TRB, users have to comply with para. 5 LGPLv2.1: A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a “work that uses the Library”. Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. In other words: if you use the TRB libraries in your commercial applications or Open-Source projects, you’re not creating a derivative work of Trailblazer. Your software can be distributed under any terms.
