env.sh

# This is specific to the GNU/Linux Bourne shell, and different
# shells and/or OSs will have slightly different syntax, but
# essentially this one-line scripts prepend the folder that our
# package lives in to the $PYTHONPATH environmental variable,
# so that we can import modules from our package from an
# arbitrary location in the filesystem---not only the cwd.
#
# Under Linux do
# source env.sh
# and you're ready to go.
#
# Adapt this to your OS and filesystem.
#

# See this stackoverflow question
# http://stackoverflow.com/questions/59895/getting-the-source-directory-of-a-bash-script-from-within
# for the magic in this command
