-/* Simple libdrawtext example without freetype.
+/* The "simple" example, modified to use a pre-built glyphmap instead of using freetype.
+ * This can be used when using libdrawtext-noft (built without freetype support/dependency).
+ *
+ * There is only one difference between this, and the regular usage demonstrated in
+ * examples/simple, and it's marked with an XXX comment in the code. For the rest of
+ * the details of libdrawtext usage in this code, refer to examples/simple/simple.c.
