+// Version: 2.00
+//
+// History: 1.00 -> 1.01 Change to use msDelay instead of Sleep.
+//
+// 1.01 -> 1.02 Changed to generic OpenCOM/CloseCOM for easier
+// use with other platforms.
+// 1.02 -> 1.03 Removed caps in #includes for Linux capatibility
+// Changed to use Acquire/Release 1-Wire Net functions
+// 1.03 -> 2.00 Reorganization of Public Domain Kit
