### Bond-graph based modeling tools
MTT is a set of tools for modeling dynamic physical systems using the bond-graph methodology and transforming these models into representations suitable for analysis, control, and simulation.
-----
+---
## Introduction
- MTT uses and generates `.m` files for [GNU Octave](https://www.octave.org/).
- MTT is mainly built on the [GNU](https://gnu.org/) set of tools.
- MTT uses the algebraic package [REDUCE](https://reduce-algebra.sourceforge.io/).
- MTT is based on the bond graph language; general bond graph information is available from [The Bond Graph Compendium](https://www2.engr.arizona.edu/~cellier/bg.html) homepage.

- <P><STRONG>MTT</STRONG> is a set of Model Transformation Tools based on
- bond graphs. <STRONG>MTT</STRONG> implements the theory to be found in the
- book "Metamodelling: Bond Graphs and Dynamic Systems" by Peter Gawthrop and
- Lorcan Smith published by Prentice Hall in 1996 (ISBN 0-13-489824-9).</P>
- <P>It implements two features not discussed in that book:</P>
- <UL>
- <LI>bicausal bond graphs and</LI>
- <LI>hierarchical bond graphs.</LI>
- </UL>
- <P>In the context of software, it has been said that one good tool is worth
- many packages. UNIX is a good example of this philosophy: the user can put
- together applications from a range of ready made tools. This manual
- describes the application of this philosophy to dynamic system modeling
- embodied in <STRONG>MTT</STRONG> - a set of Model Transformation Tools each
- of which implements a single transformation between system
- representations.</P>
- <P>System representations have two attributes.</P>
- <UL>
- <LI>A Form: e.g. acausal bond graph, differential algebraic, linear
- state-space etc.</LI>
- <LI>A Language: e.g. Fig, Matlab, LaTeX, Reduce, postscript etc.</LI>
- </UL>
- <P>Transformations in <STRONG>MTT</STRONG> are accomplished using
- appropriate software (e.g. Octave/Matlab, Reduce) encapsulated in UNIX
- Bourne shell scripts. The relationships between the tools are encoded in a
- Make File; thus the user can specify a final representation and all the
- necessary intermediate transformations are automatically generated.</P>

- </UL>
- <P>Each of these representations is related to other representations by an
- appropriate transformation (see section <A href="mtt.html#SEC3">1.2 What is
- a transformation?</A>. In many cases, a modeler is presented with a
- physical system and needs to make a model. In particular, a model, in this

- for example:</P>
- <UL>
- <LI>simulation,</LI>
- <LI>control system design,</LI>
- <LI>optimisation</LI>
- <LI>etc.</LI>

- <P>Indeed, for a given physical system, the modeler would need to derive a
- number of models. This process can be viewed as a series of steps; each
- involving a transformation between representations (see section <A href=
- "mtt.html#SEC3">1.2 What is a transformation?</A>.</P>
- <P>In this context, the following considerations are relevant.</P>
- <UL>
- <LI>There is a unique `core' representation of any system. There are many
- routes from this core representation, each leading to an appropriate
- model. There are many possible routes to this core representation from
- the physical system: the route chosen is a matter of convenience.</LI>
- <LI>Because the core representation is unique, it is easy to expand the
- tool-box to include additional transformations from the physical system
- to the core representation and additional transformations from the core
- representation to the mode.</LI>
- <LI>Transformation_1 probably cannot, and certainly should not, be
- completely automated. Engineering insight, knowledge and experience is
- essential to capture the essence (with respect to the particular use) of
- the physical system whilst discarding irrelevant form.</LI>
- <LI>Representation_1 should be `close' in some sense to the Physical
- system.</LI>
- <LI>The core representation, and hence the representations leading to it,
- must contain enough information to generate all of the required
- models.</LI>
- <LI>Representations must be easily extensible: it must be possible to add
- extra components or attributes without restructuring the
- representation.</LI>
- </UL>
- <P>I happen to believe that Bond graphs (see section <A href=
- "mtt.html#SEC4">1.3 What is a bond graph?</A>) provide the most convenient
- and powerful basis for the core representation.</P>

+ <strong>MTT</strong> is a set of Model Transformation Tools based on bond
+ graphs. <strong>MTT</strong> implements the theory to be found in the book
+ "Metamodelling: Bond Graphs and Dynamic Systems" by Peter Gawthrop and
+ Lorcan Smith published by Prentice Hall in 1996 (ISBN 0-13-489824-9).
+ </p>
+ <p>It implements two features not discussed in that book:</p>
+ <ul>
+ <li>bicausal bond graphs and</li>
+ <li>hierarchical bond graphs.</li>
+ </ul>
+ <p>
+ In the context of software, it has been said that one good tool is worth
+ many packages. UNIX is a good example of this philosophy: the user can put
+ together applications from a range of ready made tools. This manual
+ describes the application of this philosophy to dynamic system modeling
+ embodied in <strong>MTT</strong> - a set of Model Transformation Tools
+ each of which implements a single transformation between system
+ representations.
+ </p>
+ <p>System representations have two attributes.</p>
+ <ul>
+ <li>
+ A Form: e.g. acausal bond graph, differential algebraic, linear
+ state-space etc.
+ </li>
+ <li>A Language: e.g. Fig, Matlab, LaTeX, Reduce, postscript etc.</li>
+ </ul>
+ <p>
+ Transformations in <strong>MTT</strong> are accomplished using appropriate
+ software (e.g. Octave/Matlab, Reduce) encapsulated in UNIX Bourne shell
+ scripts. The relationships between the tools are encoded in a Make File;
+ thus the user can specify a final representation and all the necessary
+ intermediate transformations are automatically generated.

+ <p>Physical systems have many representations. These include</p>
+ <ul>
+ <li>a schematic diagram,</li>
+ <li>a block diagram,</li>
+ <li>a bunch of equations,</li>
+ <li>a single differential(-algebraic) equation,</li>
+ <li>simulation code,</li>
+ <li>linearised state-space (or descriptor) equations,</li>
+ <li>transfer function (of the linearised system),</li>
+ <li>frequency response (of the linearised system),</li>
+ <li>etc...</li>
+ </ul>
+ <p>
+ Each of these representations is related to other representations by an
+ appropriate transformation (see section
+ <a href="mtt.html#SEC3">1.2 What is a transformation?</a>. In many cases,
+ a modeler is presented with a physical system and needs to make a model.
+ In particular, a model, in this context, is a representation of the system
+ appropriate to a particular use, for example:
+ </p>
+ <ul>
+ <li>simulation,</li>
+ <li>control system design,</li>
+ <li>optimisation</li>
+ <li>etc.</li>
+ </ul>
+ <p>
+ Indeed, for a given physical system, the modeler would need to derive a
+ number of models. This process can be viewed as a series of steps; each
+ involving a transformation between representations (see section
+ <a href="mtt.html#SEC3">1.2 What is a transformation?</a>.
+ </p>
+ <p>In this context, the following considerations are relevant.</p>
+ <ul>
+ <li>
+ There is a unique `core' representation of any system. There are many
+ routes from this core representation, each leading to an appropriate
+ model. There are many possible routes to this core representation from
+ the physical system: the route chosen is a matter of convenience.
+ </li>
+ <li>
+ Because the core representation is unique, it is easy to expand the
+ tool-box to include additional transformations from the physical system
+ to the core representation and additional transformations from the core
+ representation to the mode.
+ </li>
+ <li>
+ Transformation_1 probably cannot, and certainly should not, be
+ completely automated. Engineering insight, knowledge and experience is
+ essential to capture the essence (with respect to the particular use) of
+ the physical system whilst discarding irrelevant form.
+ </li>
+ <li>
+ Representation_1 should be `close' in some sense to the Physical system.
+ </li>
+ <li>
+ The core representation, and hence the representations leading to it,
+ must contain enough information to generate all of the required models.
+ </li>
+ <li>
+ Representations must be easily extensible: it must be possible to add
+ extra components or attributes without restructuring the representation.
+ </li>
+ </ul>
+ <p>
+ I happen to believe that Bond graphs (see section
+ <a href="mtt.html#SEC4">1.3 What is a bond graph?</a>) provide the most
+ convenient and powerful basis for the core representation.

+ <!--docid::SEC10::-->
+ The constitutive relationship of a system component (see section
+ <a href="mtt.html#SEC7">1.6 Components</a>) typically contains symbolic
+ parameters. For example a resistor may have a symbolic resistance r. It is
+ convenient to leave such parameters as symbols when viewing equations or
+ when performing symbolic analysis such as differentiation.
+ <p>
+ However, <strong>MTT</strong> allows replacement of symbolic parameters by

+ <h2>1.8 Switched systems</h2>
+ <!--docid::SEC13::-->
+ <p>
+ Some systems contain switch-like components. For example an electrical
+ system may contain on-off switches and diodes and a hydraulic system may
+ shut-off valves and non-return valves.
+ </p>
+ <p>
+ Such systems are sometimes called hybrid systems. The modelling an
+ simulation of such systems is the subject of current research.
+ <strong>MTT</strong> implements a simple pragmatic approach to the
+ modelling and simulation of such systems via two new Bond Graph
+ components:

- <STRONG>MTT</STRONG> generates a lot of representations in a number of

- actively working with a particular system. These are two versions:
- <OL>
- <LI><CODE>mtt system clean</CODE></LI>
- <LI><CODE>mtt clean</CODE></LI>
- </OL>The first removes all files that can be regenerated with
- <STRONG>MTT</STRONG> associated with system `system'; the second removes
- all such files associated with all systems in the current working
- directory.
- <P>The files which remain after such a clean are the Defining
- representations (see section <A href="mtt.html#SEC53">6.2 Defining

- <H3>2.4.4 Version control</H3><!--docid::SEC27::-->
- <P>When you are working on a modeling project, it is easy to forget what
- changes you made to a system and why you made them. Sometimes, you may
- regret some changes and wish to revert to an earlier version: even if you
- use .old files this may be difficult to achieve safely.</P>
- <P>These are very similar problems to those faced by software developers
- and can be solved in the same way: using version
- control.<STRONG>MTT</STRONG> provides version control using the standard
- GNU Revision Control System (RCS). This is hidden from the user, but is
- fully complementary to direct use of RCS (e.g. via emacs vc commands) to
- the more experienced user who wishes to do so.</P>
- <P>The only files that you should ever change (i.e. the ones never
- overwritten by <STRONG>MTT</STRONG>) are the Defining representations (see
- section <A href="mtt.html#SEC53">6.2 Defining representations</A>).</P>
- <P>All of the files, with the exception of <CODE>system_abg.fig</CODE>, are
- initially created by <STRONG>MTT</STRONG> and contain the RCS header for
- version control.</P>
- <P>The <STRONG>MTT</STRONG> version control will automatically expand this
- part of the text to include all change comments that you give it -- so will
- direct use of RCS (e.g. via emacs vc commands)</P>
- <P>The <STRONG>MTT</STRONG> version commands are as follows:</P>
- <DL compact>
- <DT><A name="IDX93" id="IDX93"></A> <CODE>mtt system representation
- vc</CODE></DT>
- <DD><A name="IDX94" id="IDX94"></A> Apply version control to
- representation `representation' of system `system'.</DD>
- <DT><A name="IDX95" id="IDX95"></A> <CODE>mtt system vc</CODE></DT>
- <DD><A name="IDX96" id="IDX96"></A> Apply version control to all
- representations (under version control) system `system'.</DD>
- </DL>
- <P>The first is appropriate after you have made a revision to a single
- file. It will prompt you for a change comment; this will be automatically
- included in the file header. In addition, enough information will be saved
- to enable any version to be retrieved via RCS.</P>
- <P>The second is appropriate to record the state of the entire model. This
- assumes that all relevant files have been recorded by the first version of
- the command. Once again, old versions of the entire model can be retrieved
- using the relevant RCS commands.</P>
- <P>A subdirectory `RCS' is created to hold this information. You need not
- bother about the contents, except that you must not delete any files within
- `RCS'.</P>

+ <strong>MTT</strong> generates a lot of representations in a number of
+ languages. Some of these you will edit yourself; others can always be
+ recreated by <strong>MTT</strong>. It makes sense, therefore to have a
+ utility that removes all of these other files when you have finished
+ actively working with a particular system. These are two versions:
+ <ol>
+ <li><code>mtt system clean</code></li>
+ <li><code>mtt clean</code></li>
+ </ol>
+ The first removes all files that can be regenerated with
+ <strong>MTT</strong> associated with system `system'; the second removes all
+ such files associated with all systems in the current working directory.
+ <p>
+ The files which remain after such a clean are the Defining representations
+ (see section <a href="mtt.html#SEC53">6.2 Defining representations</a>).

+ <h3>2.4.4 Version control</h3>
+ <!--docid::SEC27::-->
+ <p>
+ When you are working on a modeling project, it is easy to forget what
+ changes you made to a system and why you made them. Sometimes, you may
+ regret some changes and wish to revert to an earlier version: even if you
+ use .old files this may be difficult to achieve safely.
+ </p>
+ <p>
+ These are very similar problems to those faced by software developers and
+ can be solved in the same way: using version control.<strong>MTT</strong>
+ provides version control using the standard GNU Revision Control System
+ (RCS). This is hidden from the user, but is fully complementary to direct
+ use of RCS (e.g. via emacs vc commands) to the more experienced user who
+ wishes to do so.
+ </p>
+ <p>
+ The only files that you should ever change (i.e. the ones never
+ overwritten by <strong>MTT</strong>) are the Defining representations (see
+ section <a href="mtt.html#SEC53">6.2 Defining representations</a>).
+ </p>
+ <p>
+ All of the files, with the exception of <code>system_abg.fig</code>, are
+ initially created by <strong>MTT</strong> and contain the RCS header for
+ version control.
+ </p>
+ <p>
+ The <strong>MTT</strong> version control will automatically expand this
+ part of the text to include all change comments that you give it -- so
+ will direct use of RCS (e.g. via emacs vc commands)
+ </p>
+ <p>The <strong>MTT</strong> version commands are as follows:</p>
+ <dl compact>
+ <dt>
+ <a name="IDX93" id="IDX93"></a>
+ <code>mtt system representation vc</code>
+ </dt>
+ <dd>
+ <a name="IDX94" id="IDX94"></a> Apply version control to representation
+ `representation' of system `system'.
+ </dd>
+ <dt><a name="IDX95" id="IDX95"></a> <code>mtt system vc</code></dt>
+ <dd>
+ <a name="IDX96" id="IDX96"></a> Apply version control to all
+ representations (under version control) system `system'.
+ </dd>
+ </dl>
+ <p>
+ The first is appropriate after you have made a revision to a single file.
+ It will prompt you for a change comment; this will be automatically
+ included in the file header. In addition, enough information will be saved
+ to enable any version to be retrieved via RCS.
+ </p>
+ <p>
+ The second is appropriate to record the state of the entire model. This
+ assumes that all relevant files have been recorded by the first version of
+ the command. Once again, old versions of the entire model can be retrieved
+ using the relevant RCS commands.
+ </p>
+ <p>
+ A subdirectory `RCS' is created to hold this information. You need not
+ bother about the contents, except that you must not delete any files
+ within `RCS'.

+ <h2>3.2 Creating simple models</h2>
+ <!--docid::SEC30::-->
+ <p>
+ For then purposes of this section, simple models are those which are built
+ up from bond graphs involving predefined components. In contrast, more
+ complex systems (see section
+ <a href="mtt.html#SEC31">3.3 Creating complex models</a>) need to be built
+ up hierarchically.
+ </p>
+ <p>The recommended sequence of steps to create a simple model is:</p>
+ <ol>
+ <li>
+ Decide on a name for the system; let us call it `syst' for the purposes
+ of this discussion.
+ </li>
+ <li>
+ Invoke the Bond Graph editor to draw the acausal Bond Graph.
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">
+ <pre>
+ mtt syst abg fig
+</pre
+ >
+ </td>
+ </tr>
+ </table>
+ </li>
+ <li>
+ Draw the Bond Graph (see section
+ <a href="mtt.html#SEC56">6.4.1 Language fig (abg.fig)</a>), including
+ the bonds (see section <a href="mtt.html#SEC6">1.5 Bonds</a>), the
+ components (see section <a href="mtt.html#SEC7">1.6 Components</a>) and
+ any artwork (see section <a href="mtt.html#SEC71">6.4.1.15 Artwork</a>)
+ to make the Bond Graph more readable. The graphical editor xfig is (see
+ section <a href="mtt.html#SEC166">10.2 Xfig</a>) is self-explanatory.
+ The icon library is helpful here (see see section
+ <a href="mtt.html#SEC57">6.4.1.1 Icon library</a>).
+ </li>
+ <li>
+ Add causal strokes (see section
+ <a href="mtt.html#SEC59">6.4.1.3 Strokes</a>) where needed to define
+ causality. As a general rule, use the minimum number of strokes needed
+ to define the problem; this will often be only on the
+ <code>SS</code> components. (see section
+ <a href="mtt.html#SEC62">6.4.1.6 SS components</a>). Save the bond
+ graph.
+ </li>
+ <li>
+ View the corresponding causal bond graph.
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">
+ <pre>
+ mtt syst cbg view
+</pre
+ >
+ </td>
+ </tr>
+ </table>
+ <ol>
+ <li>
+ At this stage, <strong>MTT</strong> will warn you that the labeled
+ components do not appear in the label file - this can safely be
+ ignored.
+ </li>
+ <li>
+ <strong>MTT</strong> will indicate the percentage of components
+ which are causally complete -- ideally this will be 100\%.
+ Components which are not causally complete will be listed.
+ </li>
+ <li>
+ A view of the causal bond graph will be created. The added causal
+ strokes are indicated in blue, undercausal components in green and
+ overcausal components in red.
+ </li>
+ <li>
+ If the bond graph is causally complete, proceed to the next step,
+ otherwise think hard and return to the first step.
+ </li>
+ </ol>
+ </li>
+ <li>
+ At this stage, no constitutive relationships have been defined.
+ Nevertheless, <strong>MTT</strong> will proceed in a semi-qualitative
+ fashion by assuming that all constitutive relationships are unity (and
+ therefore linear). It may be useful at this stage to view various
+ derived representations to check the overall model properties before
+ proceeding further. For example:

+ <h1>4. Simulation</h1>
+ <!--docid::SEC33::-->
+ One purpose of modelling is to simulate the modeled dynamic system. Although
+ this is just another transformation (see section
+ <a href="mtt.html#SEC3">1.2 What is a transformation?</a>) and therefore is
+ covered in the appropriate chapter (see section
+ <a href="mtt.html#SEC51">6. Representations</a>), it is important enough to
+ be given its own chapter.
+ <p>
+ Simulation is typically performed using an appropriate simulation language
+ (which is often inappropriately conflated with modelling tools).
+ <strong>MTT</strong> provides a number of alternative routes to simulation
+ based on the following representations (see section
+ <a href="mtt.html#SEC51">6. Representations</a>):

+ <h1>5. Sensitivity models</h1>
+ <!--docid::SEC50::-->
+ <p>
+ The sensitivity model of a system is a set of equations giving the
+ sensitivity of the system outputs with respect to system parameters.
+ <strong>MTT</strong> has built in methods for assisting with the
+ development of such models.
+ </p>
+ <p>
+ This feature is experimental at the moment, but the following example
+ gives an idea of what can be achieved.

- </TABLE>The sensitivity system src is automatically created from the system
- rc using the predefined sR and sC components together with vector junctions
- (see section <A href="mtt.html#SEC70">6.4.1.14 Vector Components</A>). The

- <P>Each representation is implemented in one or more languages depending on

+ <!--docid::SEC51::-->
+ <p>
+ As discussed in <a href="mtt.html#SEC2">1.1 What is a representation?</a>,
+ a system has many representations. The purpose of <strong>MTT</strong> is
+ to provide an easy way to generate such representation by applying the
+ appropriate sequence of transformations. The representations supported by
+ <strong>MTT</strong> are summarised in
+ <a href="mtt.html#SEC52">6.1 Representation summary</a>.
+ </p>
+ <p>
+ There is a two-fold division of representations into those with which the
+ user defines the system and its various attributes, and those which are
+ derived from these. The <em>defining representations</em> are listed in
+ <a href="mtt.html#SEC53">6.2 Defining representations</a>.
+ </p>
+ <p>
+ Each representation is implemented in one or more languages depending on
+ its use. These languages are discussed in
+ <a href="mtt.html#SEC159">9. Languages</a> and are associated with
+ appropriate tools for modifying or viewing the representations.

+ <!--docid::SEC60::-->
+ <p>
+ Components are represented by a text string in fig. The recommended style
+ is: 20pt, Times-Roman and centre justified.
+ </p>
+ <p>The component text string can be of the following forms:</p>
+ <dl compact>
+ <dt><a name="IDX259" id="IDX259"></a> <code>type</code></dt>
+ <dd>
+ <a name="IDX260" id="IDX260"></a> Just the type of the component is
+ indicated. Components may be either Simple components (see section
+ <a href="mtt.html#SEC61">6.4.1.5 Simple components</a>) or Compound
+ components (see section
+ <a href="mtt.html#SEC64">6.4.1.8 Compound components</a>). For example:
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">
+ <pre>
+R
+</pre
+ >
+ </td>
+ </tr>
+ </table>
+ </dd>
+ <dt><a name="IDX261" id="IDX261"></a> <code>type:label</code></dt>
+ <dd>
+ <a name="IDX262" id="IDX262"></a> Both the type and the label of the
+ component are given. The type must be a valid name (see section
+ <a href="mtt.html#SEC72">6.4.1.16 Valid Names</a>.The name provides a
+ link to more information to be found in See section
+ <a href="mtt.html#SEC83">6.6 Labels (lbl)</a>. For example:
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">

+R:r
+</pre
+ >
+ </td>
+ </tr>
+ </table>
+ </dd>
+ <dt><a name="IDX263" id="IDX263"></a> <code>type:label:cr</code></dt>
+ <dd>
+ <a name="IDX264" id="IDX264"></a> Not only are the type and the label of
+ the component given, but also the component cr argument. The type must
+ be a valid name (see section
+ <a href="mtt.html#SEC72">6.4.1.16 Valid Names</a>.The name provides a
+ link to more information to be found in See section
+ <a href="mtt.html#SEC83">6.6 Labels (lbl)</a>. For example:

+ <a name="IDX265" id="IDX265"></a> <code>type:label:expression</code>
+ </dt>
+ <dd>
+ <a name="IDX266" id="IDX266"></a> Expression is a mathematical
+ expression relating the effort (called mtt_e) to the flow (called
+ mtt_f). For example the following three forms are equivalent
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">
+ <pre>
+R:r:mtt_e=r*mtt_f
R:r:mtt_e-r*mtt_f=0
R:r:mtt_f=mtt_e/r
-</PRE>
- </TD>
- </TR>
- </TABLE>A non-linear example is:
- <TABLE>

- <DT><A name="IDX267" id="IDX267"></A> <CODE>type*n</CODE></DT>
- <DD>
- <A name="IDX268" id="IDX268"></A> The name, together with the number
- `<SAMP>n</SAMP>' of repetitions of the component, are given. This
- repetition only makes sense if the component has an even number of
- ports (see section <A href="mtt.html#SEC67">6.4.1.11 Port labels</A>);
- n copies of the component are concatenated with odd Named ports (see
- section <A href="mtt.html#SEC67">6.4.1.11 Port labels</A>) of the
- component being connected to the even Named ports of the previous
- component in the chain in numerical order. This feature is particularly
- useful if the component is compound and can be used for, example to
- give a lumped approximation of a distributed system. For example:
- <TABLE>

- <TD></TD>
- <TD class="example">

+ <!--docid::SEC67::-->
+ Most multi-port components have ports see section
+ <a href="mtt.html#SEC8">1.6.1 Ports</a>)which display different behaviors;
+ the exception to this is the junction (<code>0</code> and <code>1</code>)
+ components. For this reason, <strong>MTT</strong> provides a method for
+ unambiguously identifying the ports of a multi-port component by port
+ labels.
+ <p>
+ A port label is indicated by a name within parentheses of the form
+ <code>[name]</code>, where `name' is a name consisting of alphanumeric
+ characters and underscore; for example:
+ </p>
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">
+ <pre>
+[Mechanical_1]
+</pre
+ >
+ </td>
+ </tr>
+ </table>
+ This provides a label for corresponding to the component to which the
+ nearest bond-end is attached.
+ <p>The following rules must be be obeyed:</p>
+ <ul>
+ <li>
+ If a component has any port labels at all, there must be one for each
+ port of the component.
+ </li>
+ </ul>
+ <p>
+ Port labels may be grouped into vector port labels (see section
+ <a href="mtt.html#SEC68">6.4.1.12 Vector port labels</a>). Components with
+ compatible (ie containing the same number of ports) vector ports may be
+ connected by a <em>single</em> bond (see section
+ <a href="mtt.html#SEC6">1.5 Bonds</a>); such a bond implies the
+ corresponding number of bonds (one for each element of the vector port
+ label). All such bonds inherit the same direction and any
+ <em>explicit</em> causal strokes (see section

+ <h2>6.6 Labels (lbl)</h2>
+ <!--docid::SEC83::-->
+ Bond graph components have optional labels. These provide pointers to
+ further information relating to the component; this avoids clutter on the
+ bond graph.
+ <p>
+ The label file contains the following non-blank lines (blank lines are
+ ignored)
+ </p>
+ <ul>
+ <li>Summary - lines beginning with #SUMMARY</li>
+ <li>Description - lines beginning with #DESCRIPTION</li>
+ <li>Alias - lines beginning with #ALIAS</li>
+ <li>Comments - lines beginning with #</li>
+ <li>Labels - other non-blank lines</li>
+ </ul>
+ <p>
+ Note, for compatability with old versions, % may be used in place of #;
+ but the use of % is deprecated. Each lable contains three fields (in the
+ following order) separated by white space and on one line:
+ </p>
+ <ol>
+ <li>
+ The component name see section
+ <a href="mtt.html#SEC86">6.6.3 Component names</a>. This must be a valid
+ name (see section <a href="mtt.html#SEC72">6.4.1.16 Valid Names</a>.
+ </li>
+ <li>
+ The component constitutive relationship see section
+ <a href="mtt.html#SEC87">6.6.4 Component constitutive relationship</a>

+ </li>
+ </ol>
+ <p>
+ Not each component see section
+ <a href="mtt.html#SEC60">6.4.1.4 Components</a> needs a label, only those
+ which are explicitly labeled on the Bond Graph see section

+ <strong>MTT</strong> checks whether all components labelled on the bond
+ graph have labels and vice versa.

+ (see section <a href="mtt.html#SEC68">6.4.1.12 Vector port labels</a>) on
+ the bond graph using a short-hand notation. With in a component label file
+ (see section <a href="mtt.html#SEC83">6.6 Labels (lbl)</a>) statements of
+ the following forms can occur
+ <table>
+ <tr>
+ <td></td>
+ <td class="example">
+ <pre>
+%ALIAS short_label real_label
+</pre
+ >
+ </td>
+ </tr>
+ </table>
+ <p>
+ When the component is used within another component, the short_lable may
+ be used in place of the real_label. More than one alias per label can be

+ </p>
+ <table>

+ <h2>7.2 New (DIY) representations</h2>
+ <!--docid::SEC149::-->
+ <p>
+ It may be convenient to create new representations for
+ <strong>MTT</strong>; in particular, it is nice to be able to include the
+ result of some numerical or symbolic computations within an
+ <strong>MTT</strong> report (see section
+ <a href="mtt.html#SEC144">6.16 Report (rep)</a>). Therefore
+ <strong>MTT</strong> provides a mechanism for doing this.
+ </p>
+ <p>
+ Future extensions of <strong>MTT</strong> will use such representations
+ stored in $MTT_REP.
+ </p>
+ <p>There are three parts to creating a DIY representation called myrep</p>
+ <ol>
+ <li>Creating a make file in Make format called myrep_rep.make</li>
+ <li>Optionally creating a shell script called myrep_rep.sh</li>
+ <li>
+ Optionally creating a documentation file in LaTeX format called
+ myrep_rep.tex
+ </li>
+ </ol>

+ <strong>MTT</strong> and the two arguments `SYS' (the system name) and
+ `LANG' (the language) are passed to it by <strong>MTT</strong>. Note that

+ If <strong>MTT</strong> does not recognise a component (eg named
+ MyComponent) as a simple component (see section
+ <a href="mtt.html#SEC61">6.4.1.5 Simple components</a>) or as already
+ existing, it searches the library search path $MTT_COMPONENTS (see section
+ <a href="mtt.html#SEC182">11.4.2 $MTT_COMPONENTS</a>) for a directory
+ called MyComponent containing MyComponent_lbl.txt. It then copies the
+ <em>entire</em> directory into the current working directory. Thus, for
+ example, the directory could contain MyComponent_desc.tex
+ MyComponent_abg.fig MyComponent_lbl.txt and MyComponent_cr.r in addition
+ to MyComponent_lbl.txt.

- <OL>
- <LI>PREAMBLE
- <P>The purpose of this License is to make a manual, textbook, or other
- functional and useful document <EM>free</EM> 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.</P>
- <P>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.</P>
- <P>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.</P>
- </LI>
- <LI>APPLICABILITY AND DEFINITIONS
- <P>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.</P>
- <P>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.</P>
- <P>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.</P>
- <P>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.</P>
- <P>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.</P>
- <P>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".</P>
- <P>Examples of suitable formats for Transparent copies include plain
- ASCII without markup, Texinfo input format, LaTeX input format,
- <SPAN class="c3">SGML</SPAN> or <SPAN class="c3">XML</SPAN> using a
- publicly available <SPAN class="c3">DTD</SPAN>, and standard-conforming
- simple <SPAN class="c3">HTML</SPAN>, PostScript or <SPAN class=
- "c3">PDF</SPAN> designed for human modification. Examples of
- transparent image formats include <SPAN class="c3">PNG</SPAN>,
- <SPAN class="c3">XCF</SPAN> and <SPAN class="c3">JPG</SPAN>. Opaque
- formats include proprietary formats that can be read and edited only by
- proprietary word processors, <SPAN class="c3">SGML</SPAN> or
- <SPAN class="c3">XML</SPAN> for which the <SPAN class="c3">DTD</SPAN>
- and/or processing tools are not generally available, and the
- machine-generated <SPAN class="c3">HTML</SPAN>, PostScript or
- <SPAN class="c3">PDF</SPAN> produced by some word processors for output
- purposes only.</P>
- <P>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.</P>
- <P>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.</P>
- <P>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.</P>
- </LI>
- <LI>VERBATIM COPYING
- <P>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.</P>
- <P>You may also lend copies, under the same conditions stated above,
- and you may publicly display copies.</P>
- </LI>
- <LI>COPYING IN QUANTITY
- <P>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.</P>
- <P>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.</P>
- <P>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 computer-network 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.</P>
- <P>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.</P>
- </LI>
- <LI>MODIFICATIONS
- <P>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:</P>
- <OL>
- <LI>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.</LI>
- <LI>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.</LI>
- <LI>State on the Title page the name of the publisher of the Modified
- Version, as the publisher.</LI>
- <LI>Preserve all the copyright notices of the Document.</LI>
- <LI>Add an appropriate copyright notice for your modifications
- adjacent to the other copyright notices.</LI>
- <LI>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.</LI>
- <LI>Preserve in that license notice the full lists of Invariant
- Sections and required Cover Texts given in the Document's license
- notice.</LI>
- <LI>Include an unaltered copy of this License.</LI>
- <LI>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.</LI>
- <LI>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.</LI>
- <LI>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.</LI>
- <LI>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.</LI>
- <LI>Delete any section Entitled "Endorsements". Such a section may
- not be included in the Modified Version.</LI>
- <LI>Do not retitle any existing section to be Entitled "Endorsements"
- or to conflict in title with any Invariant Section.</LI>
- <LI>Preserve any Warranty Disclaimers.</LI>
- </OL>
- <P>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.</P>
- <P>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.</P>
- <P>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.</P>
- <P>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.</P>
- </LI>
- <LI>COMBINING DOCUMENTS
- <P>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.</P>
- <P>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.</P>
- <P>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."</P>
- </LI>
- <LI>COLLECTIONS OF DOCUMENTS
- <P>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.</P>
- <P>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.</P>
- </LI>
- <LI>AGGREGATION WITH INDEPENDENT WORKS
- <P>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.</P>
- <P>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.</P>
- </LI>
- <LI>TRANSLATION
- <P>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.</P>
- <P>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.</P>
- </LI>
- <LI>TERMINATION
- <P>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.</P>
- </LI>
- <LI>FUTURE REVISIONS OF THIS LICENSE
- <P>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 <A href=
- "http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.</P>
- <P>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.</P>

+ formats include proprietary formats that can be read and edited only
+ by proprietary word processors, <span class="c3">SGML</span> or
+ <span class="c3">XML</span> for which the
+ <span class="c3">DTD</span> and/or processing tools are not generally

+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ VERBATIM COPYING
+ <p>
+ 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.
+ </p>
+ <p>
+ You may also lend copies, under the same conditions stated above, and
+ you may publicly display copies.
+ </p>
+ </li>
+ <li>
+ COPYING IN QUANTITY
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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 computer-network 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ MODIFICATIONS
+ <p>
+ 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:
+ </p>
+ <ol>
+ <li>
+ 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.
+ </li>
+ <li>
+ 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.
+ </li>
+ <li>
+ State on the Title page the name of the publisher of the Modified
+ Version, as the publisher.
+ </li>
+ <li>Preserve all the copyright notices of the Document.</li>
+ <li>
+ Add an appropriate copyright notice for your modifications adjacent
+ to the other copyright notices.
+ </li>
+ <li>
+ 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.
+ </li>
+ <li>
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+ </li>
+ <li>Include an unaltered copy of this License.</li>
+ <li>
+ 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.
+ </li>
+ <li>
+ 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.
+ </li>
+ <li>
+ 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.
+ </li>
+ <li>
+ 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.
+ </li>
+ <li>
+ Delete any section Entitled "Endorsements". Such a section may not
+ be included in the Modified Version.
+ </li>
+ <li>
+ Do not retitle any existing section to be Entitled "Endorsements" or
+ to conflict in title with any Invariant Section.
+ </li>
+ <li>Preserve any Warranty Disclaimers.</li>
+ </ol>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ COMBINING DOCUMENTS
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ 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."
+ </p>
+ </li>
+ <li>
+ COLLECTIONS OF DOCUMENTS
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ AGGREGATION WITH INDEPENDENT WORKS
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ TRANSLATION
+ <p>
+ 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.
+ </p>
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ TERMINATION
+ <p>
+ 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.
+ </p>
+ </li>
+ <li>
+ FUTURE REVISIONS OF THIS LICENSE
+ <p>
+ 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
+ <a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a
+ >.
+ </p>
+ <p>
+ 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.

- <H3>A.2.1 Preamble</H3><!--docid::SEC191::-->
- <P>The licenses for most software are designed to take away your freedom to
- share and change it. By contrast, the GNU General Public License is
- intended to guarantee your freedom to share and change free software--to
- make sure the software is free for all its users. This General Public
- License applies to most of the Free Software Foundation's software and to
- any other program whose authors commit to using it. (Some other Free
- Software Foundation software is covered by the GNU Library General Public
- License instead.) You can apply it to your programs, too.</P>
- <P>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 this service
- 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.</P>
- <P>To protect your rights, we need to make restrictions that forbid anyone
- to deny you these rights or to ask you to surrender the rights. These
- restrictions translate to certain responsibilities for you if you
- distribute copies of the software, or if you modify it.</P>
- <P>For example, if you distribute copies of such a program, whether gratis
- or for a fee, you must give the recipients all the rights that you have.
- 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.</P>
- <P>We protect your rights with two steps: (1) copyright the software, and
- (2) offer you this license which gives you legal permission to copy,
- distribute and/or modify the software.</P>
- <P>Also, for each author's protection and ours, we want to make certain
- that everyone understands that there is no warranty for this free software.
- If the software is modified by someone else and passed on, we want its
- recipients to know that what they have is not the original, so that any
- problems introduced by others will not reflect on the original authors'
- reputations.</P>
- <P>Finally, any free program is threatened constantly by software patents.
- We wish to avoid the danger that redistributors of a free program will
- individually obtain patent licenses, in effect making the program
- proprietary. To prevent this, we have made it clear that any patent must be
- licensed for everyone's free use or not licensed at all.</P>
- <P>The precise terms and conditions for copying, distribution and
- modification follow.</P>
- <DIV class="c1">
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
- </DIV>
- <OL>
- <LI>This License applies to any program or other work which contains a
- notice placed by the copyright holder saying it may be distributed under
- the terms of this General Public License. The "Program", below, refers to
- any such program or work, and a "work based on the Program" means either
- the Program or any derivative work under copyright law: that is to say, a
- work containing the Program or a portion of it, either verbatim or with
- modifications and/or translated into another language. (Hereinafter,
- translation is included without limitation in the term "modification".)
- Each licensee is addressed as "you".
- <P>Activities other than copying, distribution and modification are not
- covered by this License; they are outside its scope. The act of running
- the Program is not restricted, and the output from the Program is
- covered only if its contents constitute a work based on the Program
- (independent of having been made by running the Program). Whether that
- is true depends on what the Program does.</P>
- </LI>
- <LI>You may copy and distribute 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
- and disclaimer of warranty; keep intact all the notices that refer to
- this License and to the absence of any warranty; and give any other
- recipients of the Program a copy of this License along with the Program.
- <P>You may charge a fee for the physical act of transferring a copy,
- and you may at your option offer warranty protection in exchange for a
- fee.</P>
- </LI>
- <LI>You may modify your copy or copies of the Program or any portion of
- it, thus forming a work based on the Program, and copy and distribute
- such modifications or work under the terms of Section 1 above, provided
- that you also meet all of these conditions:
- <OL>
- <LI>You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.</LI>
- <LI>You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any part
- thereof, to be licensed as a whole at no charge to all third parties
- under the terms of this License.</LI>
- <LI>If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a notice
- that there is no warranty (or else, saying that you provide a
- warranty) and that users may redistribute the program under these
- conditions, and telling the user how to view a copy of this License.
- (Exception: if the Program itself is interactive but does not
- normally print such an announcement, your work based on the Program
- is not required to print an announcement.)</LI>
- </OL>
- <P>These requirements apply to the modified work as a whole. If
- identifiable sections of that work are not derived from the Program,
- and can be reasonably considered independent and separate works in
- themselves, then this License, and its terms, do not apply to those
- sections when you distribute them as separate works. But when you
- distribute the same sections as part of a whole which is a work based
- on the Program, the distribution of the whole must be on the terms of
- this License, whose permissions for other licensees extend to the
- entire whole, and thus to each and every part regardless of who wrote
- it.</P>
- <P>Thus, it is not the intent of this section to claim rights or
- contest your rights to work written entirely by you; rather, the intent
- is to exercise the right to control the distribution of derivative or
- collective works based on the Program.</P>
- <P>In addition, mere aggregation of another work not based on the
- Program with the Program (or with a work based on the Program) on a
- volume of a storage or distribution medium does not bring the other
- work under the scope of this License.</P>
- </LI>
- <LI>You may copy and distribute the Program (or a work based on it, under
- Section 2) in object code or executable form under the terms of Sections
- 1 and 2 above provided that you also do one of the following:
- <OL>
- <LI>Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections 1
- and 2 above on a medium customarily used for software interchange;
- or,</LI>
- <LI>Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your cost
- of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,</LI>
- <LI>Accompany it with the information you received as to the offer to
- distribute corresponding source code. (This alternative is allowed
- only for noncommercial distribution and only if you received the
- program in object code or executable form with such an offer, in
- accord with Subsection b above.)</LI>
- </OL>
- <P>The source code for a work means the preferred form of the work for
- making modifications to it. For an executable work, complete source
- code means all the source code for all modules it contains, plus any
- associated interface definition files, plus the scripts used to control
- compilation and installation of the executable. However, as a special
- exception, the source code distributed need not include anything that
- is normally distributed (in either source or binary form) with the
- major components (compiler, kernel, and so on) of the operating system
- on which the executable runs, unless that component itself accompanies
- the executable.</P>
- <P>If distribution of executable or object code is made by offering
- access to copy from a designated place, then offering equivalent access
- to copy the source code from the same place counts as distribution of
- the source code, even though third parties are not compelled to copy
- the source along with the object code.</P>
- </LI>
- <LI>You may not copy, modify, sublicense, or distribute the Program
- except as expressly provided under this License. Any attempt otherwise to
- copy, modify, sublicense or distribute the Program 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.</LI>
- <LI>You are not required to accept this License, since you have not
- signed it. However, nothing else grants you permission to modify or
- distribute the Program or its derivative works. These actions are
- prohibited by law if you do not accept this License. Therefore, by
- modifying or distributing the Program (or any work based on the Program),
- you indicate your acceptance of this License to do so, and all its terms
- and conditions for copying, distributing or modifying the Program or
- works based on it.</LI>
- <LI>Each time you redistribute the Program (or any work based on the
- Program), the recipient automatically receives a license from the
- original licensor to copy, distribute or modify the Program subject to
- these terms and conditions. You may not impose any further restrictions
- on the recipients' exercise of the rights granted herein. You are not
- responsible for enforcing compliance by third parties to this
- License.</LI>
- <LI>If, as a consequence of a court judgment or allegation of patent
- infringement or for any other reason (not limited to patent issues),
- 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 distribute
- so as to satisfy simultaneously your obligations under this License and
- any other pertinent obligations, then as a consequence you may not
- distribute the Program at all. For example, if a patent license would not
- permit royalty-free redistribution of the Program by all those who
- receive copies directly or indirectly through you, then the only way you
- could satisfy both it and this License would be to refrain entirely from
- distribution of the Program.
- <P>If any portion of this section is held invalid or unenforceable
- under any particular circumstance, the balance of the section is
- intended to apply and the section as a whole is intended to apply in
- other circumstances.</P>
- <P>It is not the purpose of this section to induce you to infringe any
- patents or other property right claims or to contest validity of any
- such claims; this section has the sole purpose of protecting the
- integrity of the free software distribution system, which is
- implemented by public license practices. Many people have made generous
- contributions to the wide range of software distributed through that
- system in reliance on consistent application of that system; it is up
- to the author/donor to decide if he or she is willing to distribute
- software through any other system and a licensee cannot impose that
- choice.</P>
- <P>This section is intended to make thoroughly clear what is believed
- to be a consequence of the rest of this License.</P>
- </LI>
- <LI>If the distribution and/or use of the Program is restricted in
- certain countries either by patents or by copyrighted interfaces, the
- original copyright holder who places the Program under this License may
- add an explicit geographical distribution limitation excluding those
- countries, so that distribution is permitted only in or among countries
- not thus excluded. In such case, this License incorporates the limitation
- as if written in the body of this License.</LI>
- <LI>The Free Software Foundation may publish revised and/or new versions
- of the 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.
- <P>Each version is given a distinguishing version number. If the
- Program specifies a version number of this License which applies to it
- and "any later version", you have the option of following the terms and
- conditions either of that version or of any later version published by
- the Free Software Foundation. If the Program does not specify a version
- number of this License, you may choose any version ever published by
- the Free Software Foundation.</P>
- </LI>
- <LI>If you wish to incorporate parts of the Program into other free
- programs whose distribution conditions are different, write to the author
- to ask for permission. For software which is copyrighted by the Free
- Software Foundation, write to the Free Software Foundation; we sometimes
- make exceptions for this. Our decision will be guided by the two goals of
- preserving the free status of all derivatives of our free software and of
- promoting the sharing and reuse of software generally.

+ <h3>A.2.1 Preamble</h3>
+ <!--docid::SEC191::-->
+ <p>
+ The licenses for most software are designed to take away your freedom to
+ share and change it. By contrast, the GNU General Public License is
+ intended to guarantee your freedom to share and change free software--to
+ make sure the software is free for all its users. This General Public
+ License applies to most of the Free Software Foundation's software and to
+ any other program whose authors commit to using it. (Some other Free
+ Software Foundation software is covered by the GNU Library General Public
+ License instead.) You can apply it to your programs, too.
+ </p>
+ <p>
+ 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 this service
+ 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.
+ </p>
+ <p>
+ To protect your rights, we need to make restrictions that forbid anyone to
+ deny you these rights or to ask you to surrender the rights. These
+ restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+ </p>
+ <p>
+ For example, if you distribute copies of such a program, whether gratis or
+ for a fee, you must give the recipients all the rights that you have. 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.
+ </p>
+ <p>
+ We protect your rights with two steps: (1) copyright the software, and (2)
+ offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+ </p>
+ <p>
+ Also, for each author's protection and ours, we want to make certain that
+ everyone understands that there is no warranty for this free software. If
+ the software is modified by someone else and passed on, we want its
+ recipients to know that what they have is not the original, so that any
+ problems introduced by others will not reflect on the original authors'
+ reputations.
+ </p>
+ <p>
+ Finally, any free program is threatened constantly by software patents. We
+ wish to avoid the danger that redistributors of a free program will
+ individually obtain patent licenses, in effect making the program
+ proprietary. To prevent this, we have made it clear that any patent must
+ be licensed for everyone's free use or not licensed at all.
+ </p>
+ <p>
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+ </p>
+ <div class="c1">
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+ </div>
+ <ol>
+ <li>
+ This License applies to any program or other work which contains a
+ notice placed by the copyright holder saying it may be distributed under
+ the terms of this General Public License. The "Program", below, refers
+ to any such program or work, and a "work based on the Program" means
+ either the Program or any derivative work under copyright law: that is
+ to say, a work containing the Program or a portion of it, either
+ verbatim or with modifications and/or translated into another language.
+ (Hereinafter, translation is included without limitation in the term
+ "modification".) Each licensee is addressed as "you".
+ <p>
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running the Program is not restricted, and the output from the Program
+ is covered only if its contents constitute a work based on the Program
+ (independent of having been made by running the Program). Whether that
+ is true depends on what the Program does.
+ </p>
+ </li>
+ <li>
+ You may copy and distribute 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 and
+ disclaimer of warranty; keep intact all the notices that refer to this
+ License and to the absence of any warranty; and give any other
+ recipients of the Program a copy of this License along with the Program.
+ <p>
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a
+ fee.
+ </p>
+ </li>
+ <li>
+ You may modify your copy or copies of the Program or any portion of it,
+ thus forming a work based on the Program, and copy and distribute such
+ modifications or work under the terms of Section 1 above, provided that
+ you also meet all of these conditions:
+ <ol>
+ <li>
+ You must cause the modified files to carry prominent notices stating
+ that you changed the files and the date of any change.
+ </li>
+ <li>
+ You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any part
+ thereof, to be licensed as a whole at no charge to all third parties
+ under the terms of this License.
+ </li>
+ <li>
+ If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive
+ use in the most ordinary way, to print or display an announcement
+ including an appropriate copyright notice and a notice that there is
+ no warranty (or else, saying that you provide a warranty) and that
+ users may redistribute the program under these conditions, and
+ telling the user how to view a copy of this License. (Exception: if
+ the Program itself is interactive but does not normally print such
+ an announcement, your work based on the Program is not required to
+ print an announcement.)
+ </li>
+ </ol>
+ <p>
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Program,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Program, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote
+ it.
+ </p>
+ <p>
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Program.
+ </p>
+ <p>
+ In addition, mere aggregation of another work not based on the Program
+ with the Program (or with a work based on the Program) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+ </p>
+ </li>
+ <li>
+ You may copy and distribute the Program (or a work based on it, under
+ Section 2) in object code or executable form under the terms of Sections
+ 1 and 2 above provided that you also do one of the following:
+ <ol>
+ <li>
+ Accompany it with the complete corresponding machine-readable source
+ code, which must be distributed under the terms of Sections 1 and 2
+ above on a medium customarily used for software interchange; or,
+ </li>
+ <li>
+ Accompany it with a written offer, valid for at least three years,
+ to give any third party, for a charge no more than your cost of
+ physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+ </li>
+ <li>
+ Accompany it with the information you received as to the offer to
+ distribute corresponding source code. (This alternative is allowed
+ only for noncommercial distribution and only if you received the
+ program in object code or executable form with such an offer, in
+ accord with Subsection b above.)
+ </li>
+ </ol>
+ <p>
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete source
+ code means all the source code for all modules it contains, plus any
+ associated interface definition files, plus the scripts used to
+ control compilation and installation of the executable. However, as a

+ Each time you redistribute the Program (or any work based on the

+ <!--docid::SEC192::-->
+ <p>
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these
+ terms.
+ </p>
+ <p>
+ To do so, attach the following notices to the program. It is safest to
+ attach them to the start of each source file to most effectively convey
+ the exclusion of warranty; and each file should have at least the
+ "copyright" line and a pointer to where the full notice is found.
