Trying to make a spip pedigree to dot converted to make marriage node graphs. It is a bit of a spazz at the moment.

It is:
file:///Users/eriq/Documents/eca_code/PRwP/run/Ped2Dot.awk

and I can run it like:

/run/--% spip --command-file HelhayComms.big | grep PEDIGREE | cut -d: -f 3 | awk -f Ped2Dot.awk > Helyar.dot;
/run/--% dot -Tps Helyar.dot > Helyar.eps
/run/--% epstopdf Helyar.eps 
/run/--% open Helyar.pdf 

but it just is not satisfactory at the moment!
