# ortools isn't found by Lamda with this setup, so instead of the line above 
# I also tried the following approach, moving ortools directly into the 
# project root. This works to the extend that it finds the ortools but it is
# still unable to import pywrapcp.
# Hence the following lines are purely included for illustration purposes.
#
# zip -ur $DEST_DIR/dist.zip ./**; -x "ortools*"; 
#
# cd $(find $directory -type d -name "ortools")/..;
# zip -ur $DEST_DIR/dist.zip ortools;
