+within LaTeX with minimal user instructions and without the need of external
+programs.  It builds upon the TikZ package and leverages the graph placement
+algorithms from TikZ in order to automate the placement of many vertices.
+@code{tikz-feynman} allows fine-tuned placement of vertices so that even
+complex diagrams can still be generated with ease.")
