What I had in mind was what the Parport PPS generator does, only with
output through a GPIO. Since no LPT is there on the rasPi, this doesn't
exist for it unfortunately, but the source code could serve as a

As far as I understand the sources, setting up an echo allows a PPS
client to register a callback function with the PPS device to be called
when a PPS event happens. The default echo function simply outputs
"echo: assert" or "echo: clear". I guess one could indeed toggle a GPIO
from a suitably defined PPS client.
