Introduction
Sedtrans05 is a sediment transport model for continental shelf and estuaries. It predicts
the sediment transport at one location as function water depth, sediment type, current and
waves (single point model).
Sedtrans05 computes the boundary layer parameter for pure current, or pure waves or
combined current-waves conditions. The threshold of movements is computed as
function of grain size, sediment density, water salinity and temperature. Five different
transport equations are available for non-cohesive sediments (sand). Type and dimension
of bedform are also predicted and taken into account for the hydrodynamic calculations.
The Cohesive Sediment Algorithm model can be used for cohesive sediment to model the
full cycle of bed erosion, transport in suspension including flocculation and deposition.
Sedtrans05 is described in following publication: Neumeier U., Ferrarin C., Amos C.L.,
Umgiesser G. & Li M.Z. (2008) Sedtrans05: An improved sediment-transport model for
continental shelves and coastal waters with a new algorithm for cohesive sediments.

Sedtrans05 is composed by computation routines and that can be accessed through
following user interfaces. The different components are
- Sedtrans05 GUI, a graphic user interface for Microsoft Windows
- SED05, a console program for interactive or batch calculations
- SEDI1D, a 1D(vertical)-time model for cohesive sediment
- Fortran77 routines that can be integrated in other programs
- Sedtrans05.dll, a dynamic linked library compiled for Microsoft Windows that can
be called from other programs
- sedtrans05m, a compiled MEX-file to access Sedtrans05 from Matlab (only
compiled for Microsoft Windows)
Sedtrans05 GUI is recommended to make a few calculations, to examine how variations
in some input parameters modify the results, or for teaching purpose. To process larger
dataset or when the input data are already in a file, it is recommended to use SED05 (or
the Matlab function sedtrans05m if the data are already in Matlab).

History of Sedtrans
Sedtrans05 is the latest version of Sedtrans, which history started in the early 1980s. The
previous versions of Sedtrans were developed at the Geological Survey of Canada,
Bedford Institute of Oceanography, Dartmouth, Nova Scotia. The first versions were
known as "Atlantic Geoscience Centre (AGC) sediment transport model".
The two versions previous to Sedtrans05 were published by Michael Z. Li and Carl L.

for continental shelves. Computer and Geosciences, 21, 533-554.

Limitations of Sedtrans05
Software issues:
•
There is no check of the input values in the core Fortran77 routines of Sedtrans05.
Some limited input checks are done in the two input interfaces, sed05.exe and
Sedtrans95 GUI (Windows version), but they pick up only major problems (e.g.,
wave height larger than water depth). It is the responsibility of the user to assure that
the input values are realistic AND within the range of validity of the different
equations used. Otherwise the results will be meaningless and the program may crash.
•
For SED05.exe and SEDI1D.exe, the length of each filename (inclusive path)
specified as command-line argument is limited to 200 characters.
Physical limitations of Sedtrans05:
•
The model assume linear wave theory and not adapted for breaking wave and the
swash zone of beaches
Limitations of the Cohesive Sediment Algorithm (CSA)
•
The CSA does not model sand-mud mixture, biological processes (bioconsolidation
or bioturbation), lateral movement of fluid mud (due to current or gravitational
forces), resuspension of fluid mud by waves or instabilities of the water-sediment
interfaces (internal / Holmboe waves).
•
The flocculation equations used in the CSA are valid for seawater and brackish water
until salinity of about 10-15. Therefore the Cohesive Sediment Algorithm should not
be used for fresh water or very low salinities.
•
The CSA may not predict correctly erosion rate when long (much longer than 5 min.)
time-step TIMEDR are used. Mass conservation is always respected.
•
For cohesive sediment, a well-mixed water column is assumed. This is not adapted
for deeper subtidal areas. Sedtrans can still be used in such situation if it is combined
with a 3D hydrodynamic/sediment-transport model.

Installation of Sedtrand05 GUI
Sedtrans05 GUI should run on any computer with Windows95 or later. It was tested on
Windows 98 and Windows XP.
Sedtrans05 requires 1 to 3.5 MB disc space, depending which standard run-time library
files of VisualBasic 6 are already installed on the computer. In addition, 4 MB are needed
for temporary files during the installation.
Setrans05 GUI is programmed in VisualBasic. In order to work correctly, some standard
VisualBasic files must be copied to the SYSTEM directory and several files must be
registered. Therefore is not possible to simply copy the executable, but the Sedtrans05
GUI must be installed using the setup program.
The installation files usually come as zipped file. It may be necessary to unzip them
before starting the installation. After the installation, the installation files can be removed
from the computer.
The installation of Sedtrans05 is started with the file "setup.exe". The user must have
ADMINISTRATOR RIGHTS for the installation.
Any previous version of Sedtrans05 installed in the same destination directory will be
automatically removed during the installation procedure. However, previous examples
files for the batch version (INDATA.DAT, OUTDATA.LST INDATA.CST, which are
not copied during the installation but created with the options -e), may not longer be
correct after the upgrade to a newer version. They should be recreated with the
commands "SED05 -e" and "SED05 -ec" before being used, because the format of
input/output files may change from one version to the next..
The installations files consist of
- setup.exe
- setup.lst
- sedtrans05.cab
The installation will create a new directory (by default "C:\Program files\Sedtrans05\")
and make a short cut "Menu Start" - "Programs" - "Sedtrans05".
Following files are created in the Sedtrans05 directory:
- sedtrans05.exe
The Sedtrans05 GUI program
- sedtrans05.dll
Library file containing all the computation routines
- sed05.exe
Batch version (and interactive DOS version)
Sedtrans05 GUI does not use it directly
- sedtrans05.hlp
Help file for the Sedtrans05 GUI
- sedtrans05.cnt
additional data for the Help file
- sedtrans05.gid
additional data for the Help file
- readme.txt
A short explanation file
The use of the batch mode (sed05.exe) will create several other files (see "Use of
SED05")
It is possible to uninstall Sedtrans05 through "Control Panel" - "Add/Remove Programs".

Description of Sedtrand05 GUI
Sedtrans05 GUI give the same results than SED05 for non cohesive sediments, including
secondary results. However, cohesive sediments cannot be modelled with it.
Compared to the console interface SED05, Sedtrans05 has the advantage to present all
the input and output parameters in one widow. The results can be copied into the system
clipboard for transfer in another program. The 50 last input values and results are kept in
memory, and examination how variations in some input parameters modify the results is
also favoured by following functionalities:

Detailed instructions for using Sedtrans05 GUI are found in the help file accessed
directly from the program (Menu Help – Help Setrans05, or "F1" key).

Use of SED05
SED05 is a user-interface running in a console window. It computes the sediment
transport for one set of conditions. Only the file "sed05.exe" is necessary to run the
interactive/batch version. The program is capable to generate example and explanation
files.
The command-line option "-?" (i.e., type "sed05 -?") return a explanation of the
command-line syntax of SED05, which is reproduced in the frame below.
Command-line syntax for using the 1D version of Sedtrans05 (version 1.03)
SED05 [-b [IN-FILE [OUT-FILE]]] [-o OUT-FILE] [-c PARAMFILE] [-f] [-h] [-v]
-b
Batch mode with optionally names of input and output files
(default is interactive mode)
-o
Specify the name of the output files
-c
Modify defaults parameters according to the file PARAMFILE
-f
Only one tabular output file for non-cohesive sediments
-h
No header line in tabular output files
-v
Input water density/dyn.viscosity instead of salinity/temperature

Generate an example input-file "INDATA.DAT" for batch-mode
runs, an example file "INDATA.CST" to modify the default
parameters and write the list of abbreviations used in the
output files to the file "OUTPUT.LST"
IN-FILE must be with extension; default IN-FILE (batch mode) is
"INDATA.DAT". OUT-FILE must be without extension; default OUT-FILE
(batch and interactive modes) is "OUTPUT.*".
Examples of usage:
SED05
Interactive mode with default output files
SED05 -b cases.csv Batch mode with input "cases.csv" and output "cases.*"
For the interactive version, start "sed05.exe" without any command-line parameter. Due
to the significant number of input parameters required by the cohesive algorithm,
interactive model computation is not available for cohesive sediments. After the first run
in the interactive mode, it is possible to keep the previous input value for any parameter
by giving an empty input (simply pressing RETURN).
For the batch mode (input values from a tabular text file), start with "sed05.exe" the
command-line option "-b". Comment lines (lines with any text) and empty lines are
ignored in the input file. This mode does not produce any screen output.
The command-line option "-e" generates an example input-file (INDATA.DAT), an
explanation file for the output files (OUTPUT.LST), and an example file to modify the
default parameters with the optional command-line option "-c" (INDATA.CST).
SED05 saves the results in several ASCII files, that have all the same name but different
extensions (*.dat, *.da2, *.pro, *.txt, *.coh). See detailed output explanations in the file
"OUTPUT.LST" (generate with "sed05 -e", also reproduced in Appendix B).
11
The default input file is "INDATA.DAT" and the default output files are "OUTDATA.*".
It is possible to specify the filenames for input and output: for the interactive version with
the command-line option "-o"; for the batch mode by specifying input and output names
after the command-line option "-b".
The output files are :
- OUTDATA.txt a text file with input values, summary results and bedform predictions;
the interactive mode writes the output of this file also to the screen
- OUTDATA.dat the main results in tabular format
- OUTDATA.da2 additional output parameters in tabular format
- OUTDATA.pro profiles of current velocities and (for non-cohesive sediment)
suspended sediment concentration (SSC),
- OUTDATA.coh results of the cohesive sediment algorithm in tabular format (this file is
only created if the cohesive sediment algorithm is used)
If no output filename but only a input filename is specified for the batch mode, and its
extension not one of the output files (dat, da2, txt, pro or coh), then the input filename is
also used as output filename. This property of SED05 can be used under Microsoft
Windows to process a input file (with extension different from dat, da2, txt, pro or coh)
directly from the "Windows Explorer" (without a consol window) by creating in the
SendTo folder a shortcut with target "...\sed05.exe -b" (where ... is the location of
sed05.exe).
With the command-line option "-f", all tabular output for non-cohesive sediments
(normally files *.dat, *.da2 and *.pro) is written in only one file (*.dat) with 81 columns.
This may be more convenient if all parameter have to be processed subsequently with
another software.
The tabular output-files are tab-separated with by default a header line. The header line
can be suppressed with the command-line option "-h", which produces output-files that
can easier read be Matlab, Fortran program, etc.
With the command-line option "-v", the program does not calculate density and dynamic
viscosity of water from salinity and temperature, but read them directly as input values.
With this option the interactive version ask for density water and dynamic viscosity
instead of salinity and temperature; and the batch version expects water density (kg m-3)
in the column containing usually salinity, and dynamic viscosity (Pa s) in the column
containing usually temperature.
After the first run in the interactive mode, it is possible to keep the previous input value
for any parameter by giving an empty input (simply pressing RETURN).
All dimensional variables are in SI units. The grain-size is in metres, and not in mm as in
the graphic user interface Sedtrans05 GUI.
Some limited input checking is done. When a clearly impossible value is noticed, this
input value is refused in the interactive mode, in the batch mode the calculations are
aborted and an error code is written in the output files. All errors or warnings are reported
in the text output file *.txt, but only the first error or warning is specified in the tabular
output file *.dat. See also general limitations of Sedtrans05 below.
12
If the command-line option "-c" is used to modify some coefficients for the cohesive
sediment algorithm, the modified value are written in an additional output file *.log.
See also the section "Instructions for the Cohesive Sediment Algorithm" in this readme
file.

Use of sedtrans05m
sedtrans05m is a MEX-file function to call the Fortran77 subroutines directly from
Matlab. It operates like SED05 or a direct call the calculation routines from another
program. However, sedtrans05m has the advantage that it is not necessary to generate an
input data file and then to read the output data files, if the input data are already in Matlab
and the output is afterward processed in Matlab.
When a compiled MEX-file is available for your operating system/processor type
(sedtrans05m.dll for Windows, sedtrans05m.so for Linux), copy the compiled MEX-file
and the file sedtrans05m.m in the current Matlab directory or in a directory that is on the
Matlab path.
To compile the MEX-file, copy the source files (including sedtrans05m.f and
sedtrans05dll.f) to the current Matlab directory, and then type "mex sedtrans05m.f" at the
Matlab prompt. It is possible that Matlab must be configured for your Fortran compiler,
type "mex -help" at the Matlab prompt for information how to proceed.
The syntax for using sedtrans05m is described in the file sedtrans05m.m, which can be
shown by typing "help sedtrans05m" at the Matlab prompt, and which is reproduced
below.
OUT1 = SEDTRANS05M(IN1)
... = SEDTRANS05M(IN1,CONC,BEDCHA)
... = SEDTRANS05M(IN1,CONC,BEDCHA,IN2)
[OUT1,OUT2,OUT3,PROFILE,BEDTXT,CONC,BEDCHA] = SEDTRANS05M(...)
For non-cohesive sediments (1 <= IOPT <= 5) SEDTRANS05M takes 1 input argument.
For cohesive sediments (IOPT = 7) SEDTRANS05M takes 3 or 4 input arguments.
Between 1 and 7 output arguments can be requested.
The input and output variables to Sedtrans05 are bundled into several
arrays that follow the parameter order of the input/output
files of the batch version SED05 (except the columns IRUN and ERR).
IN1 can be an array of 15 (or 17) columns, if all IOPT1<=5 (non-cohesive) and
only output arguments OUT1 and OUT2 are requested.

Use SEDI1D
SEDI1D is a particular interface to Sedtrans05 that simulate a 1D(vertical)-time model
for cohesive sediment. It assumes an infinite, homogeneous, horizontal bed, which is
subject to various current and wave conditions over time. This simple model is not
designed to represent a natural environment, but it is perfectly adapted for modelling
processes observed in an annular flume. It was specifically written for comparing the
cohesive algorithm with experimental results in annular flumes. It is made available
because it may be useful for other persons, but it was developed and tested to be a robust,
user-friendly and versatile program. Therefore some adaptations in the code may be
necessary for particular situations.
The command-line option "-?" displays the explanations of the command-line syntax,
which is reproduced in the frame below.

SEDI1D reads input parameters from a file containing:
- on the first data line, the initial bed characteristics and the initial SSC;
- on the other data lines, several successive hydrodynamic conditions, each with a
specific duration.
The hydrodynamic conditions can be defined with the same input parameters as for
SED05. Alternatively, τ0 can be specified directly; in this case the subroutine with the
cohesive sediment algorithm (COHESIVE) is called directly, without passing through the
main subroutine SEDTRANS05. See the comments in the example input-file IN1D.DAT,
which is generated with the command-line option "-e", for more details.
The output is a tabular text file with SSC and bed characteristics for each minute or each
calling interval (whichever is shorter). See the explanation file OUT1D.LST, which is
generated with the command-line option "-e", for more details.
If error or warning are generated, they are reported in the text output file *.txt, but only
the first error or warning is specified in the tabular output file *.dat.

If the command-line option "-c" is used to modify some coefficients, the modified value
are written in an additional output file *.log.

Compilation of the source code
The main elements of Sedtrans05 (the calculations routines and the interfaces SED05 and
SEDI1D are written in FORTRAN77. They were developed with the compiler "g77", that
is freely available at http://www.gnu.org/software/fortran/
The code follow the FORTRAN77 standard with following exception:
- "IMPLICIT NONE" statements,
- comments starting with "!"
- names of variables and routines longer than 6 characters
- "INCLUDE" statements
- calls to 2 functions retrieving the command-line arguments, which are specific to the
compiler g77 (IARGC and GETARG); however the code can easily be modified to skip
this code section.
The source files for SED05 (console program for interactive or batch calculations)
consist of
- sed05.f
- sedtrans-core.f
- cohesive.f
- bedform.f
- sed_param.h
The main file is sed05.f, which contains "INDCLUDE" statements making reference to
all the other code files. Therefore only sed05.f has to be specified to the compiler.
The source files for SEDI1D (1D(vertical)-time model for cohesive sediment) consist of
- sedi1d.f
- sedtrans-core.f
- cohesive.f
- sed_param.h
The main file is sedi1d.f, which contains "INCLUDE" statements making reference to all
the other code files. Therefore only sedi1d.f has to be specified to the compiler.
The source files for the computation routines (accessed through the subroutine
SEDTRANS05) consist of
- sedtrans-core.f
- cohesive.f
- sed_param.h
contains the subroutine SEDTRANS05
referred from sedtrans-core.f with an INCLUDE statement.

- cohesive.f
- bedform.f
- sed_param.h
- sedtrans05m.m (the help file explaining the usage of the MEX-file)
The main file is sedtrans05m.f, which contains "INDCLUDE" statements making
reference to all the other code files. Therefore only sedtrans05m.f has to be specified
when compiling the MEX-file from Matlab. Compilation was tested with Matlab 6.1 and
g77 as Fortran77 compiler.

to keep sedtrans05m.m together with the compiled MEX-file.
The source files for DLL-executable (dynamic link library for Microsoft Windows)
consist of
- sedtrans05dll.f
- sedtrans-core.f
- cohesive.f
- bedform.f
- sed_param.h
- sedtrans05dll.def
The main file is sedtrans05dll.f, which contains "INDCLUDE" statements making
reference to all the other code files. Therefore only sedtrans05dll.f has to be specified
when creating the object file with the compiler. For producing the DLL, dllwrap requires
also sedtrans05dll.def, which contains the list of subroutine to be exported.
The source files for Sedtrans05 GUI (graphic user interface for Microsoft Windows)
consist of
- About_form.frm
- About_form.frx
- Batch_form.frm
- Batch_form.frx
- Fcomparison.frm
- Fcomparison.frx
- Fmain.frm
- Fmain.frx

- SEDTRANS05.HLP
- sedtrans05w.vbp
- sedtrans05w.vbw
- sedtrans05.dll
- sed05.exe
Sedtrans05GUI is programmed in Visual Basic 6. The project file is sedtrans05w.vbp.
The call to sedtrans05.dll (included in the source files, but can also be compiled
separately, see above) does not work when the program is executed within the Visual
Basic programming environment. The program must be compiled, and then
sedtrans05.dll be placed in the same directory than sedtrans05.exe.
sed05.exe (compiled console program for batch calculations) is included in the source
files. When placed in the same directory than sedtrans05.exe, it can be called directly
from Sedtrans05GUI.
21
Direct access to the computation routines from other programs
It is possible to access the single-point model Sedtrans05 from other program, either to
develop another user interface, or to integrate Sedtrans05 in larger 2D/3D
hydrodynamic/sedimentary models.
All the computations in Sedtrans05 is accessed through the subroutine SEDTRANS05 (in
the file "sedtrans-core.f"), with following two exceptions:
- the text of the bedform predictions is generated in the subroutine BEDFORM (in the
file "bedform.f"), and
- density and viscosity of water is computed from salinity and temperature in the
subroutine DENSVISC (in the file "cohesive.f").
Before the first call to SEDTRANS05, it is necessary to make one call to the subroutine
INICONST.
The input parameters of Sedtrans05 are transmitted as arguments to SEDTRANS05. The
main results are returned as arguments from SEDTRANS05, additional results are
returned in the common blocks OSCL, THRE, FRICF, TIMIN, PROF, PROFIL
(definition of common blocks in file "sed_param.h").
For explanations of the input/output argument of SEDTRANS05, see the beginning of the
SEDTRANS05 subroutine. For explanations of the additional results see the comments in
the file "sed_param.h".
NO input argument check is done in the subroutine SEDTRANS05
Specific for the non-cohesive methods (call to SEDTRANS05 with IOPT<>7):
+ If IOPT1.NE.7, then none of the input arguments for the Cohesive Sediment
Algorithm will be accessed; the arguments BEDCHA and CONC do not have to be
arrays in this case.
Specific for the Cohesive Sediment Algorithm (call to SEDTRANS05 with IOPT=7):
+ Various constants and parameters of the Cohesive Sediment Algorithm are specified in
the common block CCONST, which is initialized by the subroutine INICONST.
Expert users can change these constants/parameters by declaring the common block
CCONST (using "INCLUDE sed_param.h") in the calling program and modifying
some values AFTER the call to INICONST.
+ The subroutine BEDINI (in file "cohesive.f") is NOT tested so far.
+ The subroutine COMPACT (in file "cohesive.f") is NOT tested so far.
+ The array variable BEDCHA (describing the variations of the cohesive bed with
depth) must have at least 3 row and may have up to 50 rows. The function
CHECKBEDCHA can be used to check that information in BEDCHA is valid.
22
+ The dimension of the input/output argument CONC (concentration of each class of
suspended sediment) is specified with the PARAMETER variable NBCONC in the
file "sed_param.h". The settling velocity Ws of each element of CONC is specified in
the common block WSCLASS, variable WSI. INICONST must have been called once
before WSI is accessed.
To use CONC, the best is include the 2 following lines:
INCLUDE "sed_param.h"
DOUBLE PRECISION CONC(NBCONC)
+ See also the section "Instruction for the Cohesive Sediment Algorithm" in this manual.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
0. PREAMBLE
The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense
of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either
commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit
for their work, while not being considered responsible for modifications made by others.
This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the
same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.
We have designed this License in order to use it for manuals for free software, because free software needs free
documentation: a free program should come with manuals providing the same freedoms that the software does. But this
License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether
it is published as a printed book. We recommend this License principally for works whose purpose is instruction or
reference.
1. APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder
saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license,
unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such
manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy,
modify or distribute the work in a way requiring permission under copyright law.
A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied
verbatim, or with modifications and/or translated into another language.
A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the
relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and
contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of
mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical
connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position
regarding them.
The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant
Sections, in the notice that says that the Document is released under this License. If a section does not fit the above
definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant
Sections. If the Document does not identify any Invariant Sections then there are none.
The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the
notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a
Back-Cover Text may be at most 25 words.
A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is
available to the general public, that is suitable for revising the document straightforwardly with generic text editors or
(for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and
that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text
formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been
arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not
Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".
Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format,
LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML,
PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and
JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors,
28
SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated
HTML, PostScript or PDF produced by some word processors for output purposes only.
The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold,
legibly, the material this License requires to appear in the title page. For works in formats which do not have any title
page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the
beginning of the body of the text.
A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains
XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section
name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the
Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to
this definition.
The Document may include Warranty Disclaimers next to the notice which states that this License applies to the
Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards
disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on
the meaning of this License.
2. VERBATIM COPYING
You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that
this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in
all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical
measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may
accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow
the conditions in section 3.
You may also lend copies, under the same conditions stated above, and you may publicly display copies.
3. COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering
more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that
carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the
back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover
must present the full title with all words of the title equally prominent and visible. You may add other material on the
covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and
satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a
machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computernetwork location from which the general network-using public has access to download using public-standard network
protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must
take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent
copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque
copy (directly or through your agents or retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large
number of copies, to give them a chance to provide you with an updated version of the Document.
4. MODIFICATIONS
You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above,
provided that you release the Modified Version under precisely this License, with the Modified Version filling the role
of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of
it. In addition, you must do these things in the Modified Version:
A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of
previous versions (which should, if there were any, be listed in the History section of the Document). You may
use the same title as a previous version if the original publisher of that version gives permission.
B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications
in the Modified Version, together with at least five of the principal authors of the Document (all of its principal
authors, if it has fewer than five), unless they release you from this requirement.
C. State on the Title page the name of the publisher of the Modified Version, as the publisher.
D. Preserve all the copyright notices of the Document.
29
E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
F. Include, immediately after the copyright notices, a license notice giving the public permission to use the
Modified Version under the terms of this License, in the form shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the
Document's license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year,
new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled
"History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on
its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the
Document, and likewise the network locations given in the Document for previous versions it was based on.
These may be placed in the "History" section. You may omit a network location for a work that was published
at least four years before the Document itself, or if the original publisher of the version it refers to gives
permission.
K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve
in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given
therein.
L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or
the equivalent are not considered part of the section titles.
M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version.
N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant
Section.
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and
contain no material copied from the Document, you may at your option designate some or all of these sections as
invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These
titles must be distinct from any other section titles.
You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified
Version by various parties--for example, statements of peer review or that the text has been approved by an
organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover
Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of
Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are
acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the
previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity
for or to assert or imply endorsement of any Modified Version.
5. COMBINING DOCUMENTS
You may combine the Document with other documents released under this License, under the terms defined in section
4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the
original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and
that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be
replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make
the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or
publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled "History" in the various original documents, forming one
section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled
"Dedications". You must delete all sections Entitled "Endorsements."
6. COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents released under this License, and replace
the individual copies of this License in the various documents with a single copy that is included in the collection,
provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.
30
You may extract a single document from such a collection, and distribute it individually under this License, provided
you insert a copy of this License into the extracted document, and follow this License in all other respects regarding
verbatim copying of that document.
7. AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a
volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is
not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the
Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not
themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less
than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document
within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must
appear on printed covers that bracket the whole aggregate.
8. TRANSLATION
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of
section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but
you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant
Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty
Disclaimers, provided that you also include the original English version of this License and the original versions of
those notices and disclaimers. In case of a disagreement between the translation and the original version of this License
or a notice or disclaimer, the original version will prevail.
If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4)
to Preserve its Title (section 1) will typically require changing the actual title.
9. TERMINATION
You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License.
Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate
your rights under this License. However, parties who have received copies, or rights, from you under this License will
not have their licenses terminated so long as such parties remain in full compliance.
10. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time
to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new
problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a particular
numbered version of this License "or any later version" applies to it, you have the option of following the terms and
conditions either of that specified version or of any later version that has been published (not as a draft) by the Free
Software Foundation. If the Document does not specify a version number of this License, you may choose any version
ever published (not as a draft) by the Free Software Foundation.

Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for software and other kinds of works.
The licenses for most software and other practical works are designed to take away your freedom to share and change
the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all
versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to any other work released this way by its
authors. You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to
make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you
receive source code or can get it if you want it, that you can change the software or use pieces of it in new free
programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights.
Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities
to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients
the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you
must show them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer
you this License giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For
both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will
not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified versions of the software inside them,
although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to
change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is
precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice
for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to
those domains in future versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict
development and use of software on general-purpose computers, but in those that do, we wish to avoid the special
danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures
that patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and modification follow.
32
TERMS AND CONDITIONS
0. Definitions.
“This License” refers to version 3 of the GNU General Public License.
“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”.
“Licensees” and “recipients” may be individuals or organizations.
To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission,
other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work
“based on” the earlier work.
A “covered work” means either the unmodified Program or a work based on the Program.
To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily
liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy.
Propagation includes copying, distribution (with or without modification), making available to the public, and in some
countries other activities as well.
To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere
interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and
prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no
warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this
License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The “source code” for a work means the preferred form of the work for making modifications to it. “Object code”
means any non-source form of a work.
A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or,
in the case of interfaces specified for a particular programming language, one that is widely used among developers
working in that language.
The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in
the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only
to enable use of the work with that Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A “Major Component”, in this context, means a major
essential component (kernel, window system, and so on) of the specific operating system (if any) on which the
executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and
(for an executable work) run the object code and to modify the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs
which are used unmodified in performing those activities but which are not part of the work. For example,
Corresponding Source includes interface definition files associated with source files for the work, and the source code
for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by
intimate data communication or control flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the
Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided
the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program.
The output from running a covered work is covered by this License only if the output, given its content, constitutes a
covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license
otherwise remains in force. You may convey covered works to others for the sole purpose of having them make
33
modifications exclusively for you, or provide you with facilities for running those works, provided that you comply
with the terms of this License in conveying all material for which you do not control copyright. Those thus making or
running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms
that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not
allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling
obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or
restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the
extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you
disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users,
your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating
that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices
of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection
for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of
source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added
under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy.
This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work,
and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any
other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program
has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions
of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a
storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to
limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a
covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also
convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium),
accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software
interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium),
accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or
customer support for that product model, to give anyone who possesses the object code either (1) a copy of the
Corresponding Source for all the software in the product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no more than your reasonable cost of physically
performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no
charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source.
This alternative is allowed only occasionally and noncommercially, and only if you received the object code with
such an offer, in accord with subsection 6b.
34
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent
access to the Corresponding Source in the same way through the same place at no further charge. You need not
require recipients to copy the Corresponding Source along with the object code. If the place to copy the object
code is a network server, the Corresponding Source may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying
where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain
obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code
and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System
Library, need not be included in conveying the object code work.
A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally
used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In
determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a
particular product received by a particular user, “normally used” refers to a typical or common use of that class of
product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects
or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the
product.
“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information
required to install and execute modified versions of a covered work in that User Product from a modified version of its
Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the
conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to
the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding
Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not
apply if neither you nor any third party retains the ability to install modified object code on the User Product (for
example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support
service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in
which it has been modified or installed. Access to a network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format
that is publicly documented (and with an implementation available to the public in source code form), and must require
no special password or key for unpacking, reading or copying.
7. Additional Terms.
“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more
of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were
included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to
part of the Program, that part may be used separately under those permissions, but the entire Program remains governed
by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that
copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when
you modify the work.) You may place additional permissions on material, added by you to a covered work, for which
you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by
the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the
Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material
be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
35
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or
modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these
contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the
Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a
term that is a further restriction, you may remove that term. If a license document contains a further restriction but
permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of
that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement
of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as
exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt
otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including
any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently,
if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you
of the violation by some reasonable means, this is the first time you have received notice of violation of this License
(for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or
rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not
qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a
covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not
require acceptance. However, nothing other than this License grants you permission to propagate or modify any
covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or
propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run,
modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third
parties with this License.
An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or
subdividing an organization, or merging organizations. If propagation of a covered work results from an entity
transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work
the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with
reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For
example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License,
and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim
is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the
Program is based. The work thus licensed is called the contributor's “contributor version”.
A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already
acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or
selling its contributor version, but do not include claims that would be infringed only as a consequence of further
36
modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent
sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential
patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its
contributor version.
In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated,
not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent
infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to
enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not
available for anyone to copy, free of charge and under the terms of this License, through a publicly available network
server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or
(2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly
relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a
country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring
conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is
automatically extended to all recipients of the covered work and works based on it.
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or
is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You
may not convey a covered work if you are a party to an arrangement with a third party that is in the business of
distributing software, under which you make payment to the third party based on the extent of your activity of
conveying the work, and under which the third party grants, to any of the parties who would receive the covered work
from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies
made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the
covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to
infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to
satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence
you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further
conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a
work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey
the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the
special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network
will apply to the combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time
to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the
GNU General Public License “or any later version” applies to it, you have the option of following the terms and
conditions either of that numbered version or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of the GNU General Public License, you may choose any version ever
published by the Free Software Foundation.
37
If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used,
that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the
Program.
Later license versions may give you additional or different permissions. However, no additional obligations are
imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER
PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU
ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS
PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to
their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil
liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the
Program in return for a fee.
