Edit env

You have to add to your .bashrc :

# Passcal
export PASSCAL=/usr/local/passcal
export PASSOFT=${PASSCAL}
source ${PASSCAL}/setup/setup.sh

Be sure to logout and log back in!

Do some simple tests:

% which picpython

This should return:
/opt/passcal/other/bin/picpython

% lopt

This should display a simple digital clock.
