License
In December 1999, with the release of Zip 2.3, Info-ZIP switched from its old, ad hoc license(embodied in the COPYING file) to a new, more standard version based on the BSD license. Here is the text of the new license, which applies to all source files in Zip 2.3 and later, UnZip 5.41 and later, WiZ 5.0 and later, and MacZip 1.05 and later, except where explicitly stated otherwise:
This is version 2003-May-08 of the Info-ZIP copyright and license. The definitive version of this document should be available at ftp://ftp.info-zip.org/pub/infozip/license.html indefinitely.

2. Redistributions in binary form (compiled executables) must reproduce

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, and dynamic,
shared, or static library versions--must be plainly marked as such
and must not be misrepresented as being 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 of the Info-ZIP URL(s).
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.

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.
