Users can choose the license they wish to distribute +their software under. This means that you do not need to abide by *both* +licenses, but rather than you can choose the license which most suits your +needs. + +To rephrase this and to make it perfectly clear: +CLucene is distributed under the GNU Lesser General Public License (LGPL) + *or* +the Apache License, Version 2.0 + +However, we are an open source project, and we encourage users to use the LGPL +license and participate fully in the free software community. Dual licensing +of the CLucene source code provides open and free access to the technology both +for the GPL community and for other developers or companies that cannot use the +GPL. + +You can freely modify, extend, and improve the CLucene source code. The only +question is whether or not you must provide the source code and contribute +modifications to the community. The GNU and Apache licenses allow different +ranges of flexibility in this regard, but in the end, regardless of the license +used, we highly recommend that you submit any bugs, incompatibilities or +added features. + +Note that this same license does *not* apply to the CLucene Contributions +package. You should read the COPYING file in that directory or package for +more information.
