#
# Makefile used for building application.
# 
# The default target (all) builds application in two formats :
#
# appl.rec :     Image in S-record format used by the "load" command.
# appl.bin :     Image in binary format.
# appl.elf :     Image in ELF format.
# appl.map :     Linker generated map file.
# appl.dis :     Disassembly of image.
#
# Other targets are : 
#
# clean :    Deletes all files generated by makefile.
# depend :   Builds dependency file.
