The PCB code is commented well at strategic places. Some parts use strange 
paradigms, but most parts are pretty straightforward to understand. At 
least this is my experience hacking pcb-rnd.

Also, most parts of the PCB source doesn't suffer from the spaghetti 
effect and you can go there to check/fix things locally without first 
needing to understand the whole class hierarchy or type system or whatnot. 
Names are good too, so it's usually easy to guess a keyword to search for.
