HOWTO automate tree drawing
I updated the Trees HowTo with some code demonstrating how to automatically generate postscript trees from newick or nexus tree files. This uses the Bio::Tree::Draw::Cladogram module that will draw Phylograms or Cladograms. With a few unix tools (eps2png and epstopdf [part of TeX]) you can generate png and pdf files automatically making this an easy addition to phylogenetic pipelines that generate webpages as well as stand alone applications.
