%global _description %{expand:
hfsynpy is a Python translation of the transmission-line calculator in
KiCad's PCB calculator: it synthesizes and analyzes microstrip and related
lines (width from impedance, impedance and effective permittivity from
geometry). Hertzon uses it in its filter and antenna design tools.}
