+// A small example that demonstrates how SemiHosting can be used.
+// You could use it with a board that supports GDB, such as the BBC micro:bit:
+// 1. Compile and debug it:
+//      tinygo gdb -target=microbit -ocd-output tinygo.org/x/drivers/examples/semihosting
+// 2. Enable semihosting in the GDB shell:
+//      monitor arm semihosting enable
+// 3. Start the program:
+//      continue
