Query: Feynman rules for the strong and $\Delta S =1$ weak chiral Lagrangian   We present Feynman rules for the strong and $\Delta S = 1$ weak chiral
Lagrangian which are relevant for calculating $K\to \pi\pi\pi$ decay
amplitudes. Feynman rules for this specific case turn out to be too lengthy to
be included in a research paper. Since they are not standard, we decide to
include them in a separate article, making them available for any one who is
interested in this kind of calculation. Any found mistakes and (/or) comments
are warmly welcome so that corrections can be made.
