Just BTW, the readme.txt is wrong about where wee_extension is
stored.....as under a deb install it is stored in /usr/share/weewx/
When I run the suggested command, this is what I get.
pi@raspberrypi:~ $ wee_extension --install=/usr/share/weewx/wee_extension
Request to install '/usr/share/weewx/wee_extension'
