Feyn: a Metafont for Feynman diagrams ------------------------------------- %%VERSION%% 0.1 This describes the font `feyn', which can be used to produce relatively simple Feynman diagrams within equations in a LaTeX document. The other Feynman diagram package which exists is Thorsten Ohl's `feynmf/feynmp' package. That works by creating Metafont or MetaPost figures using a preprocessor. It's more general than this package, but is at its best when creating relatively large diagrams, for figures. In contrast, the present system consists of a carefully-designed font with which you can write simple diagrams, within equations or within text, in a size matching the surrounding text size. Status ------ The font, and this associated style file, should be regarded as beta software at present. The propagators and vertices which are implemented are those which _I_ needed. I'd be delighted to add more if folk feel they would be useful. Installation ------------ Extract the package file from the distribution file using `latex feyn.ins'. The resulting `feyn.sty' should be installed in the usual location for style files -- that is, something like `texmf.local/tex/latex/feyn.sty'. The Metafont source files `*.mf' should be installed in a directory with a location such as `texmf.local/fonts/source/feyn/' (on a system which has the command, `kpsepath mf' will indicate the possibilities here, but these typically include the current directory). 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 `mktexpk' for example) should work as normal, and they should be invoked by default when you LaTeX the feyn.dtx file.
