+##  Provides the following targets:

+##  all:        Wrapper for the elf binary
+##  flash:      Uses GDB to flash the target via Black Magic
+##  debug:      Flashes the target and allows for debugging using gdb and Black Magic
+##  debug-tui:  Flashes the target and allows for debugging using gdb's TUI and Black Magic
