+
+  Locate the rte_version.h file and parse out the version information.
+
+  If RTE_SDK is set, then it is used to locate the file. If the
+  RTE_SDK variable is not set then the current working directory
+  is used.
+
+  The default output of the version is 'DPDK Version: YY.MM.MINOR'
+	e.g. 'dpdk-version.sh' gives 'DPDK Version: 17.08.0'
+
+  Options: Only one option can be used at a time.
+
+  '-h' prints usage messages
+
+  '-l' prints out the full version string
+	e.g. 'dpdk-version.sh -l' gives 'DPDK-17.08.0-rc0'
+
+  '-s' prints a shorter version string
+	e.g. 'dpdk-version.sh -s' gives '17.08.0'
+
+  '-m' prints out information is comma delimited format.
+	e.g. 'dpdk-version.sh -m' give 'DPDK,17,08,0,-rc0'
+
+  '-p' prints out a Python readable format of the version.
+	e.g. 'dpdk-version.sh -m' gives
+
+	version = {
+		'prefix': 'DPDK',
+		'year': '17',
+		'month': '08',
+		'minor': '0',
+		'suffix': '-rc'
