Administration:
 R_FDL_GetVersionString
The following sub-chapters describe the Flash operations that can be initiated and controlled by the
library. The operations are initiated by a library function R_FDL_Execute and later on controlled by the
library function R_FDL_Handler.
All FDL interface functions are prototyped in the header file r_fdl.h.
