LICENSE
-------

LZMA SDK is licensed under two licenses:

1) GNU Lesser General Public License (GNU LGPL)
2) Common Public License (CPL)

It means that you can select one of these two licenses and
follow rules of that license.

SPECIAL EXCEPTION
Igor Pavlov, as the author of this code, expressly permits you
to statically or dynamically link your code (or bind by name)
to the files from LZMA SDK without subjecting your linked
code to the terms of the CPL or GNU LGPL.
Any modifications or additions to files from LZMA SDK, however,
are subject to the GNU LGPL or CPL terms.


SPECIAL EXCEPTION allows you to use LZMA SDK in applications with closed code,
while you keep LZMA SDK code unmodified.


SPECIAL EXCEPTION #2: Igor Pavlov, as the author of this code, expressly 
permits
you to use this code under the same terms and conditions contained in the 
License
Agreement you have for any previous version of LZMA SDK developed by Igor 
Pavlov.

SPECIAL EXCEPTION #2 allows owners of proprietary licenses to use latest 
version
of LZMA SDK as update for previous versions.


SPECIAL EXCEPTION #3: Igor Pavlov, as the author of this code, expressly 
permits
you to use code of examples (LzmaTest.c, LzmaStateTest.c, LzmaAlone.cpp) as
public domain code.


GNU LGPL and CPL licenses are pretty similar and both these
licenses are classified as

1) "Free software licenses" at http://www.gnu.org/
2) "OSI-approved" at http://www.opensource.org/



LZMA SDK also can be available under a proprietary license which
can include:

1) Right to modify code without subjecting modified code to the
terms of the CPL or GNU LGPL
2) Technical support for code

To request such proprietary license or any additional consultations,
send email message from that page:
