This software is provided "as is," without warranty of any kind, express

for any direct, indirect, incidental, special or consequential damages
arising out of the use of or inability to use this software.
Permission is granted to anyone to use this software for any purpose,
including commercial applications, and to alter it and redistribute it
freely, subject to the above disclaimer and the following restrictions:
1. Redistributions of source code (in whole or in part) must retain
the above copyright notice, definition, disclaimer, and this list
of conditions.
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.
