+/*
+Package cl provides a binding to the OpenCL api. It's mostly a low-level
+wrapper that avoids adding functionality while still making the interface
+a little more friendly and easy to use.
+
+Resource life-cycle management:
+
+For any CL object that gets created (buffer, queue, kernel, etc..) you should
+call object.Release() when finished with it to free the CL resources. This
+explicitely calls the related clXXXRelease method for the type. However,
+as a fallback there is a finalizer set for every resource item that takes
+care of it (eventually) if Release isn't called. In this way you can have
+better control over the life cycle of resources while having a fall back
+to avoid leaks. This is similar to how file handles and such are handled
+in the Go standard packages.
