planwhich is mentioned in the SYNOPSIS. The other thing I did was trying GraphViz::ISA, which is a nice module for visualising ISA relations (Actually the whole GraphViz thing is a very nice module for visualising any kind of relation). The problem is that it does not support showing relations for multiple modules but shows only the tree for one module. I wanted it to show the whole Curses::UI Widget set and ended up doing a real nasty hack to make it do so. This actually looks quite nice, but I'd like to do it more cleanly and have it in GraphViz::ISA for later use. So I can add this to my TODO list. Will be fun.
