-----------------------------------------------


Version numbers
---------------

See engineVersion.txt and virusDataVersion.txt.


Installation instructions
-------------------------

To install, download both the SAVI and virus data packages, and run the
following commands:

    tar xf (savi package).tar
    cd sav-install
    unzip ../(data package).zip
    sudo ./install.sh

By default the product will be installed under /usr/local.

Run "./install.sh -h" to see more information and how to change the defaults.

When installed, use the sweep command to scan files. "sweep -v" will report
the installed SAVI and virus data versions, and "sweep -h" will list the
other command line options.

                           ACKNOWLEDGMENTS

* We used "Screaming Fast Galois Field Arithmetic Using Intel SIMD Instructions" 
  paper by James S. Plank, Kevin M. Greenan and Ethan L. Miller to improve Reed-Solomon 
  coding performance. Also we are grateful to Artem Drobanov and Bulat Ziganshin 
  for samples and ideas allowed to make Reed-Solomon coding more efficient.

* RAR text compression algorithm is based on Dmitry Shkarin PPMII and Dmitry 
  Subbotin carryless rangecoder public domain source code. You may find it in 
  ftp.elf.stuba.sk/pub/pc/pack.

* RAR encryption includes parts of code from Szymon Stefanek and Brian Gladman 
  AES implementations also as Steve Reid SHA-1 source.

       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.

XZ Utils

XZ Utils Licensing
==================

Different licenses apply to different files in this package. Here is a rough 
summary of which licenses apply to which parts of this package (but check the 
individual files to be sure!):

  - liblzma is in the public domain.

  - xz, xzdec, and lzmadec command line tools are in the public domain unless 
    GNU getopt_long had to be compiled and linked in from the lib directory. The 
    getopt_long code is under GNU LGPLv2.1+.

  - The scripts to grep, diff, and view compressed files have been	adapted 
    from gzip. These scripts and their documentation are under GNU GPLv2+.

  - All the documentation in the doc directory and most of the  XZ Utils specific 
    documentation files in other directories are in the public domain.

  - Translated messages are in the public domain.

  - The build system contains public domain files, and files that are under 
    GNU GPLv2+ or GNU GPLv3+. None of these files end up in the binaries being 
    built.

  - Test files and test code in the tests directory, and debugging utilities 
    in the debug directory are in the public domain.

  - The extra directory may contain public domain files, and files that are 
    under various free software licenses.

You can do whatever you want with the files that have been put into the public 
domain. If you find public domain legally problematic, take the previous sentence 
as a license grant. If you still find the lack of copyright legally problematic, 
you have too many lawyers.

As usual, this software is provided "as is", without any warranty.

If you copy significant amounts of public domain code from XZ Utils into your 
project, acknowledging this somewhere in your software is polite (especially 
if it is proprietary, non-free software), but naturally it is not legally required. 
Here is an example of a good notice to put into "about box" or into documentation:

This software includes code from XZ Utils <https://tukaani.org/xz/>.

The following license texts are included in the following files:
  - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
  - COPYING.GPLv2: GNU General Public License version 2
  - COPYING.GPLv3: GNU General Public License version 3

Note that the toolchain (compiler, linker etc.) may add some code pieces that 
are copyrighted. Thus, it is possible that e.g. liblzma binary wouldn't actually 
be in the public domain in its entirety even though it contains no copyrighted 
code from the XZ Utils source package.

If you have questions, don't hesitate to ask the author(s) for more information.

5. Time Zone Database

  ICU uses the public domain data and code derived from Time Zone
Database for its time zone support. The ownership of the TZ database
is explained in BCP 175: Procedure for Maintaining the Time Zone
Database section 7.

 # 7.  Database Ownership
 #
 #    The TZ database itself is not an IETF Contribution or an IETF
 #    document.  Rather it is a pre-existing and regularly updated work
 #    that is in the public domain, and is intended to remain in the
 #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
 #    not apply to the TZ Database or contributions that individuals make
 #    to it.  Should any claims be made and substantiated against the TZ
 #    Database, the organization that is providing the IANA
 #    Considerations defined in this RFC, under the memorandum of
 #    understanding with the IETF, currently ICANN, may act in accordance
 #    with all competent court orders.  No ownership claims will be made
 #    by ICANN or the IETF Trust on the database or the code.  Any person
 #    making a contribution to the database or code waives all rights to
 #    future claims in that contribution or in the TZ Database.
