+  NAME:
+  Demo sketch for complete printing test of LCD
+
+  DESCRIPTION:
+  The sketch demonstrates capabalities of the LCD by displaying several
+  test.
+  * The sketch is intended preferrably for 16x2 LCD, but can be configured
+    for 20x4 LCDs just by uncommenting and commenting related sections.
+  * The sketch is just for demonstration purposes, so that it is not
+    optimized for memory usage.
