+ */
+
+/**
+ * The raw32 GOS implementation supports any 32 bit processor with or without an
+ * underlying operating system. It uses cooperative multi-tasking. Be careful
+ * when writing device drivers not to disturb the assumptions this creates by performing
+ * call-backs to uGFX code unless you define the INTERRUPTS_OFF() and INTERRUPTS_ON() macros.
+ * It still requires some C runtime library support...
+ * enough startup to initialise the stack, interrupts, static data etc and call main().
+ * setjmp() and longjmp() - for threading
+ * memcpy() - for heap and threading
+ * malloc(), realloc and free() - if GOS_RAW_HEAP_SIZE == 0
+ *
+ * You must also define the following routines in your own code so that timing functions will work...
+ * systemticks_t gfxSystemTicks(void);
+ * systemticks_t gfxMillisecondsToTicks(delaytime_t ms);
