This module is a layer between the perl-internals-examining parts of Malcolm Beattie's perl compiler (the B::* classes) and your favorite graph layout tool (currently Dot and VGC are supported, but adding others would be easy). It examines the internal structures that perl builds to represent your code (OPs and SVs), and generates specifications for multicolored boxes and arrows to represent them.
