# For setting environment variables, simple relative paths like ".." could lead to unintended references
# due to how they interact with FABRIC_CFG_PATH. It's advised to specify paths more explicitly,
# such as using "../${PWD}", to ensure that Fabric's environment variables are pointing to the correct paths.
