# docker filesystem.  For this script to work, you must have the
# code base fully installed (composer install must have been run) on your 
# local machine. Adjust the 'LOCALHOST_CODE_SOURCE_DIR' variable
# below to point to your local copy. You should also have a mysqldump
# file of your database to load into the mysql container.  If you
# are so inclined, use an old dump, and the docker-compose
# process will run your doctrine migrations for you when
# spinning up the containers. Adjust 'LOCALHOST_DATABASE_DUMP_FILE'
# varibale below to point to your local datavase dump file.
