    License
    ProGuard is free. You can use it freely for processing your applications,
    commercial or not. Your code obviously remains yours after having been
    processed, and its license can remain the same.
    The ProGuard code itself is copyrighted, but its distribution license
    provides you with some rights for modifying and redistributing its code and
    its documentation. More specifically, ProGuard is distributed under the
    terms of the GNU General Public License (GPL), version 2, as published by
    the Free Software Foundation (FSF). In short, this means that you may
    freely redistribute the program, modified or as is, on the condition that
    you make the complete source code available as well. If you develop a
    program that is linked with ProGuard, the program as a whole has to be
    distributed at no charge under the GPL. I am granting a special exception
    to the latter clause (in wording suggested by the FSF), for combinations
    with the following stand-alone applications: Apache Ant, Apache Maven, the
    Google Android SDK, the Eclipse ProGuardDT GUI, the EclipseME JME IDE, the
    Oracle NetBeans Java IDE, the Oracle JME Wireless Toolkit, the Intel TXE
    SDK, the Simple Build Tool for Scala, the NeoMAD Tools by Neomades, the
    Javaground Tools, and the Sanaware Tools.
    The ProGuard user documentation is copyrighted as well. It may only be
    redistributed without changes, along with the unmodified version of the
    code.
