For a game engine I am writing, I am planning to use a heavily cut down and thoroughly modified version of the Java logging library logback. Basically I am using their code for lookups and instantiation of new loggers (so, maybe some 5% tops of the code, not that it matters).
Q: What does this mean for my engine; What does the LGPL license force me to do?
- I am not native speaker and hence have issues understanding all that legal mumbo-jumbo which forms the license.
- The question also is specifically about LGPL v2.1, as that is the license of the library I abuse.
Addendum2: to clear some confusion; the phrase '... 5% ... not that it matters', refers to the fact that it does not matter how much or how little code it is in the end, it still is licensed code and hemce has to be treated in such a matter.
