So I'd like to migrate from gschem to lepton, but that would mean me
re-implementing the --control-fd=3Dstdin facility that has just been
implemented in gschem. You mention that I can do things in "scheme". I
have no frame of reference for what "scheme" is, so I'd appreciate a couple
of pointers for how I'd go about setting up some form of IPC (preferably on
stdin, since that is what my system is geared towards) for remote control
of page saving and reverting.
Any pointers?

Again, and returning to your first post, you could use the Scheme<br>
function `sigaction', installing a handler for it, which could do<br>
the job, instead of hard working on the C side.<br>
