When I bought my Amstrad satellite receiver in the UK,
although the manual had a diagram showing where in UK to
point satellite dish at what angle, there was no diagram
extending to Europe. In Munich. there were no satellite
dishes on roofs to align to (satellite TV had not caught
on with Germans). None of technical friends &
colleagues knew, So a physics friend Chris S. gave me the
geometry, & I wrote the program.
