+//! \brief An abstract interface to a snapshot representing the state of a
+//!     process.
+//!
+//! This is the top-level object in a family of Snapshot objects, because it
+//! gives access to a SystemSnapshot, vectors of ModuleSnapshot and
+//! ThreadSnapshot objects, and possibly an ExceptionSnapshot. In turn,
+//! ThreadSnapshot and ExceptionSnapshot objects both give access to CPUContext
+//! objects, and ThreadSnapshot objects also give access to MemorySnapshot
+//! objects corresponding to thread stacks.

+  //! This method retrieves annotations recorded for a process. These

+  //! “Simple annotations” are structured as a sequence of key-value pairs,
+  //! where all keys and values are strings. These are referred to in Chrome as
+  //! “crash keys.”
+  //!
+  //! Annotations stored here may reflect the process, system, or snapshot

+  //! retrievable by this method. For clients such as Chrome, this includes the
+  //! product name and version.
+  //!
+  //! Additional per-module annotations may be obtained by calling
+  //! ModuleSnapshot::AnnotationsSimpleMap().
+  //
+  // This interface currently returns a const& because all implementations store
+  // the data within their objects in this format, and are therefore able to
+  // provide this access without requiring a copy. Future implementations may
+  // obtain data on demand or store data in a different format, at which point
+  // the cost of maintaining this data in ProcessSnapshot subclass objects will
