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 easily write simple diagrams, within equations or within text, in a +size matching the surrounding text size.</p> + +<p><img class="smallimage" src="sample-massive.png" alt="Massive fermions" +/>The propagators and vertices which are implemented are those which +seem to appear most often in non-figure displays (the practical +definition of ‘appear most often’ is ‘which I wanted’ and ‘which people +asked me for’). I have no current plans to extend the package +further, but I’m willing add other features if you can make a case for +them.</p> + +<p>There is further documentation, plus numerous examples, in the +<a href="feyn.pdf" >package documentation</a>.</p> + +<p><strong>[By the way, I have little idea of how many people actually +use this package.
