+simple driver utilities
+=======================
+
+[simple] driver usage examples.
+
+[simple]: ../../../km/src/simple
+
+Usage
+-----
+
+### exchange_ints.exe
+
+```
+Usage: exchange_ints.exe N
+```
+
+Parses its argument as an `unsigned int` and exchanges it with the one stored
+in [simple] driver's memory.
+For example:
+
+```
+> exchange_ints.exe 1
+42
+```
+
+```
+> exchange_ints.exe 32
+1
+```
+
+```
+> exchange_ints.exe 100500
+32
+```
