#   Makefile used for building application.                               *
#                                                                         *
#   The default target (all) builds application in two formats :          *
#   *.elf : Image in ELF format.                                          *
#   *.rec : Image in S-record format.                                     *
#                                                                         *
#   The linker also generates a MAP file "*.map".                         *
#                                                                         *
#   Other targets are :                                                   *
#   clean :    Deletes all files generated by makefile.                   *
#   depend :   Builds dependency file.                                    *
#                                                                         *
