# upgrade your working IDEA to the latest changes.
#
# Before you run the script, ensure you have the following:
# 1. Your project for IntelliJ IDEA CE is fully built (do 'Rebuild Project' if you're not sure)
# 2. WORK_IDEA_HOME points to the directory of IntelliJ IDEA build you want to upgrade
# 3. DEV_IDEA_HOME points to the directory of the project you built at step 1
# 4. You quit IntelliJ IDEA
