# AWS Deploy Script for Travis
# Remember to add the env var in the travis configuration
# in order to work, this scripts needs:
# AWS_ACCESS_KEY_ID: user ID
# AWS_SECRET_ACCESS_KEY: user secret
# APP_NAME: EBS application name
# ENV_NAME: EBS application env
# S3_BUCKET: name of the S3 bucket to store deployment archive
# DEPLOY_BRANCH

# Check current git branch
