    2. Redistributions in binary form (compiled executables and libraries)
       must reproduce the above copyright notice, definition, disclaimer,
       and this list of conditions in documentation and/or other materials
       provided with the distribution.  Additional documentation is not needed
       for executables where a command line license option provides these and
       a note regarding this option is in the executable's startup banner.  The
       sole exception to this condition is redistribution of a standard
       UnZipSFX binary (including SFXWiz) as part of a self-extracting archive;
       that is permitted without inclusion of this license, as long as the
       normal SFX banner has not been removed from the binary or disabled.

    3. Altered versions--including, but not limited to, ports to new operating
       systems, existing ports with new graphical interfaces, versions with
       modified or added functionality, and dynamic, shared, or static library
       versions not from Info-ZIP--must be plainly marked as such and must not
       be misrepresented as being the original source or, if binaries,
       compiled from the original source.  Such altered versions also must not
       be misrepresented as being Info-ZIP releases--including, but not
       limited to, labeling of the altered versions with the names "Info-ZIP"
       (or any variation thereof, including, but not limited to, different
       capitalizations), "Pocket UnZip," "WiZ" or "MacZip" without the
       explicit permission of Info-ZIP.  Such altered versions are further
       prohibited from misrepresentative use of the Zip-Bugs or Info-ZIP
       e-mail addresses or the Info-ZIP URL(s), such as to imply Info-ZIP
       will provide support for the altered versions.

    4. Info-ZIP retains the right to use the names "Info-ZIP," "Zip," "UnZip,"
       "UnZipSFX," "WiZ," "Pocket UnZip," "Pocket Zip," and "MacZip" for its
       own source and binary releases.
