Dear Physics 129 students,

You should regularly update your raspberry pi.
This will get you the latest softare fixes as 
well as download the latest class scripts etc 
which are being developed as we progress through
the quarter.

Here is as you do it ("linux>" is the linux prompt)

linux> cd ~/config_physrpi/scripts
linux> ./update_physrpi

When you are done you will be asked to do

linux> . /etc/bash.bashrc

Today's update will copy a couple of example scripts
in ~/physrpi/campagnari/python

C.
