[OPEN-ILS-DEV] documentation request

[Doug Kyle]

My library is trying to get this working, and after digging through 
numerous config files, logs, code, list archives, web docs, and blogs, I 
realized what I really want is a low level map of how all this should 
fit together.  What all the various applications are, their purpose, 
intputs, outputs, what other parts they interact with, etc.  Are there 
any such docs from the development process you could share?
