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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. 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". + +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. + + 1. 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. + +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. + + 2. 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: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) 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. + + c) 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.) + +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. + +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. + +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. + + 3. 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: + + a) 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, + + b) 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, + + c) 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.) + +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. + +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. + + 4. 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. + + 5. 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. + + 6. 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. + + 7. 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. + +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. + +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. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. 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. + + 9. 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. + +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. + + 10. 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. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE 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. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + 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. + + 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. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

These +% are shown in textstyle size, but all characters are also available in +% displaystyle size. All the dimensions are shown as multiples of the +% length of a module which is the length of the short fermion. The +% dimension~$a$ is the height of the maths axis. The~$\circ$ shows the +% reference point of each character. The proper vertex and the +% complete vertex are specified +% in terms of a `blob-radius' which is about half a module. They have +% a width of 2~radii, and a height and depth of 1~radius. +% +% Each of the characters marked with a~$\dag$ in the table has two +% arrowed variants, so that |\feyn{fA + gV}| produces $\feyn{fA + +% gV}$. The `A' variants produce arrows pointing rightwards or +% upwards, and the `V' variants arrows pointing leftwards or +% downwards. The characters marked with a~$\ddag$ also have an +% upside-down variant, thus `flu' is an upside-down variant of the +% fermion loop, and `fluV' an arrowed variant. +% +% The unnassigned positions in the \feynx\ font are filled +% with an obviously wrong dummy character, so that |$\feyn{A}$|, for example, +% produces $\feyn{fs0Afs0}$. +% +% The file \file{feyn.sty} additionally defines a number of macros, +% described here. +% \begin{description} +% \item[\cs{feyn}] Selects the diagram font. This must be used +% within math mode. \cs{Feyn} selects the text-mode diagram font. +% \item[\cs{momentum}\{ch\}\{text\}] sets the character +% ch, which may be a ligature, and puts the given text at the recommended +% annotation position for that character. |\momentum[pos]{ch}{text}| +% is the same, except that the optional argument indicates the +% position relative to the annotation position. It must be one of +% `top', `urt', `lrt', `bot', `llft' or `ulft'. See below for +% examples. Rarely used as such, since the |\feyn| and |\Feyn| +% commands make~`!' a temporarily active character, and define it +% to be |\momentum|. +% \item[\cs{Diagram\{\}}] For building more complicated diagrams. It +% takes one argument, which is like the contents of an \texttt{\{array\}} +% environment---a series of formulae separated by \&'s and \verb-\\-. See +% below for an example. The result is a box on the math-axis. +% \item[\cs{maxis}] Raises a formula to the math-axis, which is +% occasionally useful within in-text equations: eg +% |$\Feyn{fglf} - \maxis{\Feyn{faf}}$| produces +% $\Feyn{fglf} - \maxis{\Feyn{faf}}$. +% \item[\cs{vertexlabel\{p\}\{text\}}] Allows you to label a vertex. If +% the first parameter~$p$ is~$\wedge$, the~\emph{text} is placed above the +% point at which the command is given, if it is~\texttt{\_}, it is +% placed below. For example, |$\feyn{f\vertexlabel^{a}}$| produces +% $\feyn{f\vertexlabel^{a}}$. More often used within |\Diagram| +% than elsewhere. +% \item[\cs{feynstrut\{h\}\{d\}}] For use within an (eqn)array environment, or +% the like. It modifies the control sequence \verb-\strut- to be a strut of +% height~$h$ and depth~$d$ modules, which can therefore be used to +% space the array out. Note that it modifies |\strut|, rather +% than being the strut itself. +% \item[\cs{annotate\{x\}\{y\}\{text\}}] Puts the \emph{text}, between dollars, +% in a zero width box at offset~$(x,y)$ modules from the position of the +% |\annotate| command (which is generally the first command(s) after +% entering math-mode). Because the \emph{text} is in math-mode, anything +% that is not maths should be in an |\mbox|. +% \end{description} +% +% The \feynx\ font is modular, in the sense that all the +% dimensions are in terms of a module of 10pt, and all sizes given +% below are in units of modules. As well as 10pt, the font has +% versions for 11pt, 12pt, 18pt and 24pt text, and the most +% appropriate one is selected depending on the text size declared (or +% defaulted) in the |\documentclass| command. This range of sizes +% seems to be appropriate for the sizes required, but the author would +% welcome comments on this. The distribution +% contains a sample file using the 18pt \feynx\ font in a +% \texttt{foiltex} document. +% +% You draw a diagram by going into math-mode (between \$\dots\$), and selecting +% the diagrams font by the font-changing command \verb-\feyn{}- +% (exactly as you might use \verb-\mathrm- in math-mode). With a couple of +% exceptions, all the characters are obtained by typing a single +% letter, or a couple of letters which form a ligature, so that the +% letter~$f$ in the diagrams font (\verb-$\feyn{f}$-) produces a +% fermion of length~2 (modules), and~$fs$ produces a short fermion of +% length~1. As usual in maths mode, space characters are ignored, so +% you can add whitespace as required to make the expressions more +% legible. Some of the more heavily used characters are available in +% both display size and text size, with the text-size version invoked +% by |\Feyn{...}|, so that |\feyn{fglf}| gives $\feyn{fglf}$ and +% |\Feyn{fglf}| gives $\Feyn{fglf}$. The displaystyle characters +% are all on the math-axis, the textstyle ones are on the text line. +% +% \section{Examples} +% +% \newdimen\halftextwidth +% \halftextwidth=\textwidth +%

\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=installthings}. +% +% If you have not done so already, you need to extract the package +% file from the distribution file using |latex feyn.ins|. The +% resulting \file{feyn.sty} should be installed in the usual location +% for style files -- that is, something like +% \file{texmf.local/tex/latex/feyn.sty}. The \metafont\ source files +% \file{*.mf} should be installed in a directory with a location such as +% \file{texmf.local/fonts/source/feyn/}. That should be all you need +% to do as regards the installation of the fonts -- if your \TeX\ +% setup is installed correctly, then the usual font-generation +% commands (such as \file{mktexpk} for example) should work as normal, +% and these will usually be invoked by default when \LaTeX\ or +% pdf\LaTeX\ is run. +% +% If you are using a teTeX-based system (which is true of most Unix +% installations, and most MacOS\,X installations), then you can +% determine the style-file and \metafont\ search paths using the commands +% \begin{verbatim} +% % kpsepath tex +% % kpsepath mf +% \end{verbatim} +% respectively. After you have installed them, you will probably need +% to give the command \texttt{mktexlsr} to rebuild the paths database, +% and you can confirm that the files are findable with the commands +% \texttt{kpsewhich feyn.sty} and \texttt{kpsewhich feyn10.mf}. +% +% Users of other systems will have similar mechanisms +% for finding and confirming the search paths (and if anyone wishes to +% send me details, I can add the details to this document). +% +% \section{Acknowledgements} +% +% Thanks to Purnendu Chakraborty, Fabio Correa, and Bryan Chen for +% suggestions and testing at various times. +% +% +% \StopEventually{} +% +% \section{Implementation} +% \begin{macrocode} +%<*package> +% \end{macrocode} +% +% Start off with the available options. +% +% A wrinkle is that the |{align}| environment, which is defined +% in the amsmath package, reads its contents before processing them, +% which means that a `!' within the environment has its catcode fixed +% before it can be changed by |\feyn| or |\diagram|. To handle this +% situation, we support \Lopt{globalbang} and \Lopt{noglobalbang} +% options, which cause the `!' character to be redefined globally or +% not. The default depends on whether the amsmath package was loaded +% before this one was. +% \begin{macrocode} +\newif\ifFeyn@globalbang +\@ifpackageloaded{amsmath}{\Feyn@globalbangtrue}{\Feyn@globalbangfalse} +\DeclareOption{globalbang}{\Feyn@globalbangtrue} +\DeclareOption{noglobalbang}{\Feyn@globalbangfalse} +% \end{macrocode} +% +% Now process the options specified in the package command. +% \begin{macrocode} +\ProcessOptions +% \end{macrocode} +% +% Declare the feyn math font family. The |\skewchar| for this font +% (see the \TeX book, p431) can be set to zero, since it's a +% completely upright maths font (the least of its peculiarities). We +% don't have the font in much of a range of sizes. +% \begin{macrocode} +\DeclareFontFamily{OMS}{feyn}{\skewchar\font'000} +\DeclareFontShape{OMS}{feyn}{m}{n}{% + <-10.5>feyn10% + <10.5-11.5>feyn11% + <11.5-15>feyn12% + <15-21>feyn18% + <21->feyn24% + }{} +% \end{macrocode} +% +% Now do the same for the text-size fonts, declaring the textfeyn math +% font family. +% \begin{macrocode} +\DeclareFontFamily{OMS}{textfeyn}{\skewchar\font'000} +\DeclareFontShape{OMS}{textfeyn}{m}{n}{% + <-10.5>feyntext10% + <10.5-11.5>feyntext11% + <11.5-15>feyntext12% + <15-21>feyntext18% + <21->feyntext24% + }{} +% \end{macrocode} +% +% XXX It would be nice to arrange things so that superscripts in +% the feyn font were drawn from cmmi7, or something. The original +% feyn.sty arranged this with |\scriptfont\diagramfam=\ninmi|, but +% it's not clear what the analogue in the FSS is. +% +% Now declare the `feynman' symbol font, and make the command |\feyn| +% set its argument in that font. Similarly have |\Feyn| invoke the +% feynman symbol font for the text sizes. +% \begin{macrocode} +\DeclareSymbolFont{feynman}{OMS}{feyn}{m}{n} +\DeclareSymbolFontAlphabet{\feyn@alphabet}{feynman} +\DeclareSymbolFont{textfeynman}{OMS}{textfeyn}{m}{n} +\DeclareSymbolFontAlphabet{\Feyn@alphabet}{textfeynman} +% \end{macrocode} +% +% Now use these font-setting commands, defining |\feyn| and |\Feyn| to +% switch to the given alphabets, defining ! as a shortcut for +% |\momentum| (so that |!{x}{y}| is interpreted as |\momentum{x}{y}|). +% We have to make sure that the `!' character produces that character +% everywhere except within |\feyn| or |\Feyn|.

You might think that the +% math-axis is obtainable from |\fontdimen22| of the font, but we do +% not load it as an |{operator}| font when we invoke +% |\DeclareSymbolFont|, so it does not have all 22 parameters that a +% symbol font (as the \TeX book uses the term, rather than \LaTeXe's +% NFSS). I confess I don't \emph{really} understand the ins and outs +% of this, but this route is robust and not wrong. +% +% The character |"7F| in the feyn font is blank, but has width +% |module#| and height |a#| (using the dimensions of the font +% file). Use this to set the |\feyn@module| and |\feyn@maxis|. Note +% that the `module' used in this package file is twice the module used +% in the \metafont\ files themselves. +% \begin{macro}{\feyn@module} +% \begin{macro}{\feyn@maxis} +% \begin{macrocode} +\DeclareMathSymbol{\FeynSpaceChar}{\mathord}{feynman}{"7F} +\setbox0=\hbox{$\FeynSpaceChar$} +\newdimen\feyn@mfmodule \feyn@mfmodule=\wd0 +\newdimen\feyn@module \feyn@module=2\wd0 +\newdimen\feyn@maxis \feyn@maxis=\ht0 +% \end{macrocode} +% \end{macro} +% \end{macro} +% +% \begin{macro}{\Diagram} +% Define the |\Diagram| macro, which lays out a semi-complicated +% diagram in 2-d. +% \begin{macrocode} +{\catcode`\!=\active + \gdef\Diagram{% + \begingroup % ends in \Diagram@ + \catcode`\!=\active + \let!\momentum + \Diagram@}} +\def\Diagram@#1{\setbox0=\hbox{\vbox{\offinterlineskip \let\\\cr + \halign{&$\displaystyle\feyn{##}$\cr #1\crcr}}}% +% \end{macrocode} +% At this point, |\box0| has zero depth.

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. - -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. - -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. - -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. - -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. - -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. - -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. - -The precise terms and conditions for copying, distribution and modification -follow. - -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - -0. 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". - -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. - -1. 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. - -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. - -2. 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: - - * a) You must cause the modified files to carry prominent notices stating - that you changed the files and the date of any change. - - * b) 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. - - * c) 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.) - -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. - -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. - -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. - -3. 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: - - * a) 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, - - * b) 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, - - * c) 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.) - -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. - -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. - -4. 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. - -5. 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. - -6. 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. - -7. 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. - -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. - -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. - -This section is intended to make thoroughly clear what is believed to be a -consequence of the rest of this License. - -8. 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. - -9. 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. - -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. - -10. 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. - -NO WARRANTY - -11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.

This must be used -% within math mode. \cs{Feyn} selects the text-mode diagram font. -% \item[\cs{Diagram\{\}}] For building more complicated diagrams. It -% takes one argument, which is like the contents of an \texttt{\{array\}} -% environment---a series of formulae separated by \&'s and \verb-\\-. See -% below for an example. The result is a box on the math-axis. -% \item[\cs{maxis}] Raises a formula to the math-axis, which is -% occasionally useful within in-text equations: eg -% |$\Feyn{fglf} - \maxis{\Feyn{faf}}$| produces -% $\Feyn{fglf} - \maxis{\Feyn{faf}}$. -% \item[\cs{vertexlabel\{p\}\{text\}}] Allows you to label a vertex. If -% the first parameter~$p$ is~$\wedge$, the~\emph{text} is placed above the -% point at which the command is given, if it is~\texttt{\_}, it is -% placed below. For example, |$\feyn{fa\vertexlabel^{p}f}$| produces -% $\feyn{fa\vertexlabel^{p}f}$. -% \item[\cs{feynstrut\{h\}\{d\}}] For use within an (eqn)array environment, or -% the like. It modifies the control sequence \verb-\strut- to be a strut of -% height~$h$ and depth~$d$, which can therefore be used to space the array -% out. -% \item[\cs{annotate\{x\}\{y\}\{text\}}] Puts the \emph{text}, -% between dollars, -% in a zero width box at offset~$(x,y)$ modules from the position of the -% |\annotate| command (which is generally the first command(s) after -% entering math-mode). Because the \emph{text} is in math-mode, anything -% that is not maths should be in an |\mbox|. -% \end{description} -% \caption{\label{macros} The macros defined in \file{feyn.sty}} -% \end{table} -% -% The \feynx\ font is modular, in the sense that all the -% dimensions are in terms of a module of 10pt, and all sizes given -% below are in units of modules. As well as 10pt, the font has 11pt -% and 12pt versions, and the correct one is selected depending on the -% text size declared (or defaulted) in the |\documentclass| command.. -% -% You draw a diagram by going into math-mode (between \$\dots\$), and selecting -% the diagrams font by the font-changing command \verb-\feyn{}- -% (exactly as you might use \verb-\mathrm- in math-mode). With a couple of -% exceptions, all the characters are obtained by typing a single -% letter, or a couple of letters which form a ligature, so that the -% letter~$f$ in the diagrams font (\verb-$\feyn{f}$-) produces a -% fermion of length~2 (modules), and~$fs$ produces a short fermion of -% length~1. As usual in maths mode, space characters are ignored, so -% you can add whitespace as required to make the expressions more -% legible. Some of the more heavily used characters are available in -% both display size and text size, with the text-size version invoked -% by |\Feyn{...}|, so that |\feyn{fglf}| gives $\feyn{fglf}$ and -% |\Feyn{fglf}| gives $\Feyn{fglf}$.
