+/**
+ * @defgroup pkg_flashdb    FlashDB: Database for Flash
+ * @ingroup  pkg
+ * @brief    An ultra-lightweight embedded database
+ * @see      http://armink.gitee.io/flashdb/
+ *
+ * This package provides a Key-Value database and a Time series database
+ * that can be used with a MTD or a file system backend.
+ *
+ * It is recommended to use the use the MTD backend for performance reasons,
+ * but if you have a filesystem anyway or want to store the database as a file
+ * there is also a VFS backend that can be used instead.
+ *
+ * MTD Backend
+ * ===========
+ * To enable the MTD backend, select the `flashdb_mtd` module.
+ *
+ * FlashDB can only use a single MTD device. To assign a MTD device for FlashDB
+ * to use, call
+ *
+ * ```C
+ * fdb_mtd_init(MTD_0);
+ * ```
+ *
+ * FlashDB allows for multiple partitions on the device. They have to configured
+ * at compile time:
+ *
+ * ```
+ * CFLAGS += -DFAL_PART0_LABEL=\"part0\"
+ * CFLAGS += -DFAL_PART0_LENGTH=8*1024
+ *
+ * CFLAGS += -DFAL_PART1_LABEL=\"part1\"
+ * CFLAGS += -DFAL_PART1_LENGTH=4*1024
+ * ```
+ *
+ * The partition names have to be used in `fdb_kvdb_init()` / `fdb_tsdb_init()`.
+ *
+ * VFS Backend
+ * ===========
+ * To enable the VFS Backend, select the `flashdb_vfs` module.
+ *
+ * Here instead of partitions, FlashDB uses directories to store the data.
+ * The directory names are used instead of the partition names in `fdb_kvdb_init()` /
+ * `fdb_tsdb_init()` and you have to enable file mode by calling
+ *
+ * ```C
+ * bool file_mode = true;
+ * fdb_kvdb_control(&kvdb, FDB_KVDB_CTRL_SET_FILE_MODE, &file_mode);
+ * ```
+ *
+ * for the Key-Value database and
+ *
+ * ```C
+ * bool file_mode = true;
+ * fdb_tsdb_control(&tsdb, FDB_TSDB_CTRL_SET_FILE_MODE, &file_mode);
+ * ```
+ *
+ * for the time-series database.
+ *
+ * Key-Value database
+ * ==================
+ * To enable the Key-Value database, select the `flashdb_kvdb` module.
+ *
+ * For use of the FlashDB API, reffer to the [FlashDB documentation](http://armink.gitee.io/flashdb/#/sample-kvdb-basic).
+ *
+ * Time series database
+ * ====================
+ * To enable the Key-Value database, select the `flashdb_tsdb` module.
+ *
+ * For use of the FlashDB API, reffer to the [FlashDB documentation](http://armink.gitee.io/flashdb/#/sample-tsdb-basic).
