+// Helper Macros for determining silicon revisions, etc.
+//
+// These macros will be used by Driverlib at "run-time" to create necessary
+// conditional code blocks that will allow a single version of the Driverlib
+// "binary" code to support multiple(all) Stellaris silicon revisions.
+//
+// It is expected that these macros will be used inside of a standard 'C'
+// conditional block of code, e.g.
+//
+// if(CLASS_IS_SANDSTORM)
+// {
+// do some Sandstorm-class specific code here.
+// }
+//
+// By default, these macros will be defined as run-time checks of the
+// appropriate register(s) to allow creation of run-time conditional code
+// blocks for a common DriverLib across the entire Stellaris family.
+//
+// However, if code-space optimization is required, these macros can be "hard-
+// coded" for a specific version of Stellaris silicon. Many compilers will
+// then detect the "hard-coded" conditionals, and appropriately optimize the
+// code blocks, eliminating any "unreachable" code. This would result in
+// a smaller Driverlib, thus producing a smaller final application size, but
+// at the cost of limiting the Driverlib binary to a specific Stellaris
+// silicon revision.
