+    """libmnl is a minimalistic user-space library oriented to Netlink
+    developers.There are a lot of common tasks in parsing, validating,
+    constructing of both the Netlink header and TLVs that are repetitive
+    and easy to get wrong.This library aims to provide simple helpers
+    that allows you to re-use code and to avoid re-inventing the wheel."""
