"""
Create a directed graph, allowing multiple edges and self loops, from
a unix mailbox. The nodes are email addresses with links
that point from the sender to the recievers. The edge data
is a Python email.Message object which contains all of
the email message data.
This example shows the power of XDiGraph to hold edge data
of arbitrary Python objects (in this case a list of email messages).
By default, load the sample unix email mailbox called "unix_email.mbox".
You can load your own mailbox by naming it on the command line, eg
python unixemail.py /var/spool/mail/username
