[PD] Comments on pd as a library to be used in game

[marius schebella]

that sounds promising!
maybe still a little too ambitious for someone who does not know the pd 
source at all (aka me). is there an overall introductory explanation of 
how the various source codes components work together besides the source 
code and in code documentation itself?
