+//!scoped_lock is meant to carry out the tasks for locking, unlocking, try-locking
+//!and timed-locking (recursive or not) for the Mutex. The Mutex need not supply all
+//!of this functionality. If the client of scoped_lock<Mutex> does not use
+//!functionality which the Mutex does not supply, no harm is done. Mutex ownership
+//!transfer is supported through the syntax of move semantics. Ownership transfer
+//!is allowed both by construction and assignment. The scoped_lock does not support
+//!copy semantics. A compile time error results if copy construction or copy
+//!assignment is attempted. Mutex ownership can also be moved from an
+//!upgradable_lock and sharable_lock via constructor. In this role, scoped_lock
+//!shares the same functionality as a write_lock.
