The XBow 7Zip extraction engine is based on the LZMA SDK from
7-zip.org.
The LZMA SDK is in the public domain.
The XBow ACE engine uses the public UnAce 2.5 library from Marcel Lemke.

Public UnAce Licence
----------------------
The Public UnAce Package (v2.0 or later if not otherwise stated) is
distritbuted under the following licence:
"Package" refers to the collection of files distributed by the Copyright Holder, and derivatives
of that collection of files created through textual modification.
"Standard Version" refers to such a Package if it has not been modified, or has been modified
in accordance with the wishes of the Copyright Holder.
"Distribution" as it is used here means making data available to a third party.
No matter in which way the data is made available.
"Copyright Holder" is ACE Compression Software.
"Distribution Partner" is e-merge GmbH (authorised signatory).
1. The Standard Version of Public UnAce Package may be freely distributed.
2. The UnAce sources may be used in any software to handle ACE
archives without limitations free of charge, but must not be used
to reproduce the ACE compression algorithm.
This means that that the code must not be used to develop an
ACE compatible archiver (that is: software capable of compressing to
Ace archives) in any way.
3. Distribution of modified Public UnAce sources (as part of other software
or as stand-alone package) requires that it is clearly stated in the
documentation and source code that it is distributed under the
Public UnAce Licence.
The Public UnAce Licence has to be included in this package.
4. The name of the Copyright Holder or the support of ACE archives may not be
used to endorse or promote products derived from this package without specific
prior written permission from the Copyright Holder or its Distribution Partner.
5. This Software is distributed "AS IS".
NO WARRANTY OF ANY KIND IS EXPRESSED OR IMPLIED. YOU USE AT
YOUR OWN RISK. THE AUTHOR WILL NOT BE LIABLE FOR DATA LOSS,
DAMAGES, LOSS OF PROFITS OR ANY OTHER KIND OF LOSS WHILE USING
OR MISUSING THIS SOFTWARE.
6. Installing and using the Public UnAce Package signifies acceptance of
these terms and conditions of the license.

The XBow text extraction engine uses the libxml2 library from
xmlsoft.org for extracting
the plain text out of OOXML documents (docx, pptx, ppsx, xlsx).

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
