""" minimalstartup.py
A minimalist python startup file that sets up tab completion and command history
Author: Asa Ben-Hur

It's very easy to add tab completion and command-line history to your
python shell, and make it behave a lot like your unix command line.

All you need is a pythonstartup file, which is a file that the
interpreter calls when it starts up.  You need to tell your shell
where the file is located by setting the PYTHONSTARTUP environment
variable to the location of your python startup file.  This is done
by adding the following lines to your .bashrc file, which is located
in your home directory:

PYTHONSTARTUP=/home/asa/python/minimalstartup.py
export PYTHONSTARTUP

Adjust the location according to where you want to put your
startup file, and change this if you use a different shell.
