+
+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.

+/* managed_pointer.h
+
+These macros allow wrapping an allocator/deallocator into an object that is
+owned and managed by the Lua garbage collector.
+
+Why? It is too easy to leak objects that need to be manually released, especially
+when dealing with the Lua API which can throw errors from many operations.
+
+USAGE
+-----
+
+For example, given an object that can be created or released with the following
+functions:
+
+  fancy_buffer* new_buffer();
+  void free_buffer(fancy_buffer* p_buffer)
+
+You could declare a managed version like so:
+
+  MANAGED_POINTER_ALLOCATOR(new_managed_buffer, fancy_buffer*, new_buffer, free_buffer)
+
+And then, when you need to create a new fancy_buffer in your code:
+
+  fancy_buffer *my_buffer = new_managed_buffer(L);
+
+NOTES
+-----
+
+Managed objects MUST NOT be freed manually. They will automatically be
+freed during the next GC sweep after your function exits (even if via an error).
+
+The managed object is pushed onto the stack, but should generally be ignored,
+but you'll need to bear this in mind when creating managed pointers in the
+middle of a sequence of stack operations.
