+This file provides a shim abstraction over LuaSec, consolidating some code
+which was previously spread between net.server backends, portmanager and
+certmanager.
+
+The goal is to provide a more or less well-defined API on top of LuaSec which
+abstracts away some of the things which are not needed and simplifies usage of
+commonly used things (such as SNI contexts). Eventually, network backends
+which do not rely on LuaSocket+LuaSec should be able to provide *this* API
+instead of having to mimic LuaSec.
