+Features:
+- CPU-aware parallel processing
+- Multiple backup modes (cluster, single database, sample)
+- Interactive UI and CLI modes
+- Archive verification and restore
+- Progress indicators and timing summaries
+- Robust error handling and logging
+
+Database Support:
+- PostgreSQL (via pg_dump/pg_restore)
+- MySQL (via mysqldump/mysql)
+
+For help with specific commands, use: dbbackup [command] --help`,
