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.
