John,

Do you have any specific parts you are looking for?

HylaFAX is a client-server system.

The basic flow for sending is something like:
	clients submit jobs -> hfaxd
	hfaxd reads/writes qfiles (sendq/qXXXXX) and documents
	hfaxd communicates with faxq (the fax scheduler) about jobs over a FIFO
	faxq prepares jobs (forks and runs bin/*2ps to render jobs)
	faxq execs faxsend to send jobs
	faxq execs "NotifyCmd" to handle notification for jobs

If you have specific questions about any of them, just ask.
