    This copy of Ice is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License version 2 as
    published by the Free Software Foundation.
    Ice is distributed in the hope that it will be useful, but WITHOUT ANY
    WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS

    details.
    You should have received a copy of the GNU General Public License version
    2 along with this program; if not, see http://www.gnu.org/licenses.
    Linking Ice statically or dynamically with other software (such as a
    library, module or application) is making a combined work based on Ice.
    Thus, the terms and conditions of the GNU General Public License version
    2 cover this combined work.
    If such software can only be used together with Ice, then not only the
    combined work but the software itself is a work derived from Ice and as
    such shall be licensed under the terms of the GNU General Public License
    version 2. This includes the situation where Ice is only being used
    through an abstraction layer.
    As a special exception to the above, ZeroC grants to the contributors for
    the following projects the permission to license their Ice-based software
    under the terms of the GNU Lesser General Public License (LGPL) version
    2.1 or of the BSD license:
    - Orca Robotics (http://orca-robotics.sourceforge.net)
    - Mumble (http://mumble.sourceforge.net)
    This exception does not extend to the parts of Ice used by these
    projects, or to any other derived work: as a whole, any work based on Ice
    shall be licensed under the terms and conditions of the GNU General
    Public License version 2.
    You may also combine Ice with any software not derived from Ice, provided
    the license of such software is compatible with the GNU General Public
    License version 2. In addition, as a special exception, ZeroC grants you
    permission to combine Ice with:
    - the OpenSSL library, or with a modified version of the OpenSSL library
    that uses the same license as OpenSSL
    - any library not derived from Ice and licensed under the terms of
    the Apache License, version 2.0
    (http://www.apache.org/licenses/LICENSE-2.0.html)
    If you modify this copy of Ice, you may extend any of the exceptions
    provided above to your version of Ice, but you are not obligated to
    do so.
