it's sad to see that atmel doesn't publish their svn repo or has
a centralized location or even puts proper version/release info
into the library itself

+/// \unit
+///
+/// !!!Purpose
+///
+/// The AT45 Dataflash driver is based on the corresponding AT45 driver.
+/// A AT45 instance has to be initialized using the Dataflash levle function
+/// AT45_Configure(). AT45 Dataflash can be automatically detected using
+/// the AT45_FindDevice() function. Then AT45 dataflash operations such as
+/// read, write and erase DF can be launched using AT45_SendCommand function
+/// with corresponding AT45 command set.
+///
+/// !!!Usage
+///
+/// -# Reads data from the At45 at the specified address using AT45D_Read().
+/// -# Writes data on the At45 at the specified address using AT45D_Write().
+/// -# Erases a page of data at the given address using AT45D_Erase().
+/// -# Poll until the At45 has completed of corresponding operations using
+/// AT45D_WaitReady().
+/// -# Retrieves and returns the At45 current using AT45D_GetStatus().
