GeneTree
This is a Ruby script which scrapes the Mathemtical Genealogy Project website and creates the genealogy tree for a given name. Obviously the MGP database should have the data for the person, otherwise no tree will be formed. Right now, it uses Graphviz toolkit to create the tree and the output is in PNG format. It requires the mechanize and ruby-graphviz Ruby gems.
The script takes two arguments, the first argument should be "LastName, FirstName" and the second argument should be the number of seconds to wait between page clicks. It is highly recommended that the wait should be atleast 2 seconds. I assume no responsibility for any effects or side-effects it (or its mutations) might have.
