A command line program for extracting data from the Mathematics Genealogy Project (http://genealogy.math.ndsu.nodak.edu/index.php).

For example, if Carl Gauss wanted to explore his academic ancestors, he would type

mathgenealogy http://genealogy.math.ndsu.nodak.edu/id.php?id=18231

which will produce a directed acyclic graph in output.pdf. See

mathgenealogy --help

for details. Requires GraphViz to run.
