+Examples of methods for determining the directory path where our executable resides.
+
+-	The `kardianos/osext` package is used for reference. The other methods will
+	require that the executable is located within the OS search path.
+
+-	The first alternative utilizes `exec.LookPath` to find the executable within the
+	OS search path.
