Need to go through the bowties and make them
'D' instead, a function, that derives a derived component....
Annoying means I have to go through ALL the dia diagrams as well......
actually producting pdf files.
In each chapter directory, copy.tex
is the source file for the chapter.
A makefile should exist in each of these
directories, and this when supplied the arg copy
will make all images form dia/gnuplot etc
