I tried this fdrawgram several times recently. I must say that is a
"slow" tool. For a 45 species tree, it took more than 10 minutes to
generate the png file.
I found a better tool online at http://cgi-www.daimi.au.dk/cgi-chili/
phyfi/go . The cons are: 1. first, 2. colorful, 3. multi-format
(jpg, png, etc) for download.
So if we replace the old PHYLIP drawing program with this new one,
that will be much better.
