OPTIONS:
  --optional       Also create optional directories
  -h, --help       Show this help

DESCRIPTION:
  This script creates the base directory structure for a project
  with hexagonal architecture.

BASE DIRECTORIES (${#PROJECT_DIRECTORIES[@]}):
$(printf "  %s\n" "${PROJECT_DIRECTORIES[@]}")

OPTIONAL DIRECTORIES (${#OPTIONAL_DIRECTORIES[@]}):
$(printf "  %s\n" "${OPTIONAL_DIRECTORIES[@]}")

ENVIRONMENT VARIABLES:
  CREATE_OPTIONAL_DIRS=true    Create optional directories

EXAMPLE:
  $0                    # Base directories only
  $0 --optional         # Base + optional
  CREATE_OPTIONAL_DIRS=true $0  # Base + optional
